With two versions available for three or six K- or T-Cubes, these USB hubs are designed specifically for communication between multiple controllers and the host control PC. With the help of the Thorlabs support team I found a working solution which I want to share here. Although the PSD has only one sensor input it does have two ranges. To determine the three independent components of plane strain, three linearly independent strain measures are needed, i.e., three strain gages positioned in a rosette-like layout.. The Strain Gauge sensor can be purchased in 3 ranges: a range of 2000 ppm, 5000 ppm and 10000 ppm. What is a Strain Gauge? When used in isolation, it can measure the deflection/extension in a strain gauge with nanometer level resolution. This K-Cube unit can be used for position, force, or voltage strain-gauge reading. The FSU-SSB is a fast, compact, high precision strain bridge input module delivering high resolution readings over USB and communicated directly to a PC. On this product, or any T-cube product i would expect to be able to get a very concise overview of the entire line. BTW, why do you force me to enter an email just to make a comment for your benefit, the Security Code okay that makes a little sense, but perhaps a little explanation under the box "To Prevent Website Spamming" or some such thing. Watch the videos now to see what we mean. The basic premise of this line is the functionality offered by the entire family and the inter-play between the various modules, without the overview this presentation fails. A strain gauge is a sensor whose measured electrical resistance varies with changes in strain. In order to use a strain gauge reader like the KSG101 to monitor the feedback, the strain gauge must first be connected to a pre-amplification circuit like the AMP002 listed below. System: Windows 10 64 bit Thorlabs Kineses 32bit for 64 bit installed Python 3.7.4 32bit Response from Mike at Thorlabs: In your screenshot you are trying to use the MG17Motor ActiveX object, however the TSG001 requires the piezo control ActiveX object therefore your program will not detect the strain gauge. I'm using this as shown on this page in conjunction with the TPZ001. Response from Jeremy at Thorlabs: There is already a method for reading the output of the TSG001. The TSG unit is powered and lit up, and the device driver installs correctly and is recognized as connected by the APT firmware, but the APT user program opens to an empty window and does not allow control. Hi, The time when an external force is applied to anything. Kinesis USB Controller HubsMultiple units can be mounted and connected to a single PC by using the KCH301 or KCH601 USB Controller Hubs. It is aimed at dynamic applications that require high speed measurement. When I change the voltage, it went to the end (e.g. It enables the system to identify the piezo extension associated with the actuator. The TSG001 provides immediate 'out of the box' operation with the complete Thorlabs range of strain-gauge- Strain Gauge or Strain Gage was invented in 1938 by Edward E. Simmons and Arthur C. Ruge. Artwork: A simple example of a hydraulic strain gauge. 3.3 Input Connectors The input connectors connect the strain gage or transducer to the Model P3. Such information would be very helpful. Wire data to the Vsg input to determine the polymorphic instance to use or manually select the instance. The KSG101 K-Cube Strain Gauge Reader is designed for use with our range of strain-gauge-equipped bare piezo stacks, actuators, stages, and force sensors. *The TPS002 can only support one KNA-VIS or KNA-IR controller or one KLD101 driver and should not be used to power any additional units as that may exceed current limitations. Strain can be caused by forces, pressures, moments, heat, structural changes of the material and the like. Compatible power supplies are listed below. Thorlabs' K-Cube™ Strain Gauge Reader is a part of Thorlabs' new and growing Kinesis® line of high-end, compact motion controllers. Strain gauge directly is used for the measurement of load and indirectly it is used for the measurement of displacement. Two units of measure are able to be read and displayed such as kg & lbs. The Wheatstone Bridge is the electrical equivalent of two parallel voltage divider circuits with R 1 and R 2 as one of them and R 3 and R 4 as the other one.. Definition: A strain gauge is one of the imperative devices used in the field of geotechnical engineering to measure strain on diverse structures. Optical Table Mounting PlateEach K-Cube unit comes with a mounting plate that clips onto the base of the controller, as shown in the animation below. Details . System: Windows 10 64 bit Thorlabs Kineses 32bit for 64 bit installed Python 3.7.4 32bit The metallic strain gage consists of a very fine wire or, more commonly, metallic foil arranged in a grid pattern. It delivers high speed measurements of 4800 samples per second at 13 bits noise free resolution. Strain can be measured using various types of devices classified depending upon their principle of operation. Still not sure why v3.3 does not work. A strain gauge (also spelled strain gage) is a device used to measure strain on an object. The little stuff really does matter. If the evacuation siren sounds leave your bags and follow the instructions of your demonstrator and proceed to the evacuation area. The differential voltage of the bridge produced by variation in strain gauge resistance is amplified using the INA333. Is there anyway to solve the problem? PANEL METERS with Relays and Analog Output The popular DP25B series are accurate, economical, and easy to program.

See Figures C through F. For example, if a positive (tensile) strain is applied to gauges 1 and 3, and a negative (compressive) strain to gauges 2 and 4, the total strain would be 4 times the strain on one gauge. Whether it is in structural durability testing, structural health monitoring, or for the production of OEM transducers, HBM's optical and electrical strain gauges are the first choice. Each port can be independently configured to control the logic level or to set the trigger as an input or output. Therefore, the strain has little effect on the second gauge, called the dummy gauge. As the article tries to show in figure 4 the classical quarter bridge configuration is in fact a 3 wire system. By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and APT controllers in a single application, while only having to learn a single set of software tools. The OMEGA DP25B series Digital Panel Meters feature the biggest brightest display of any 1/8 DIN panel meter. This value is contained within brackets. The KSG101 is also compatible with the KCH301 and KCH601 USB Controller Hubs, available below. When an object deforms within the limit of elasticity, either it becomes narrower and longer or it become shorter and broadens. A Wheatstone bridge is a divided bridge circuit used for the measurement of static or dynamic electrical resistance. 1 year warranty with accessory options of a black leather carry case with shoulder strap which allows full operation of the PSD232 whilst being carried in the case. Please let me know if this force sensor can be used with TSG001 Write EPC to tag.

It measures tensile, compression, and torsional forces. By providing functionality with this common software platform, Thorlabs has ensured that users can easily mix and match any of the Kinesis controllers in a single application, while only having to learn a single set of software tools. The Case is Registered Design No. In summary, the ideal strain gauge is small in size and mass, low in cost, easily attached, and highly sensitive to strain but insensitive to ambient or process temperature variations. Alternatively, strain gauge conductors may be thin strips of the metallic film deposited on a nonconducting substrate material called the carrier. Up to 450 hours battery life can be achieved whilst in power save mode with powering via 2 x AA Alkaline batteries (not included). K-Cubes simply clip into place using the provided on-unit clips, while current- and previous-generation T-Cubes require the KAP101 Adapter Plate, shown in the animation to the below right. The strain gauge reader is also equipped with a low-voltage monitor output (0-10 V) that is proportional to the strain gauge extension, thus providing a conditioned feedback/monitoring signal for third party systems. The PSD232 sends the displayed value to the RS232 port at 9600 baud in an ASCII format, terminated by a carriage return and line-feed making it suitable for stand alone data loggers, larger serial displays as well as interfacing onto a PC for logging which can provide a useful record during a calibration or load cell test. When external forces are applied to a stationary object, stress and strain â¦ Thorlabs' K-Cube™ Strain Gauge Reader is a part of Thorlabs' new and growing Kinesis® line of high-end, compact motion controllers. The strain gage is suitable for embedment in soil or concrete. LabVIEWLabVIEW can be used to communicate with any Kinesis- or APT-based controller via .NET controls. The LabVIEW tutorial, provided below, provides some information on using the .NET controls to create control GUIs for Kinesis- and APT-driven devices within LabVIEW. The most widely used strain gage is the bonded metallic strain gage. The strain gauge or load cell handheld display with RS232 interface enables the connection to many devices whether a PC or simple data logger. However, it crashes very often. This signal is applicable to Thorlabs piezo actuators fitted with an ID resistor. The active gauge R 1 is remote from the instrumentation, and both it and its associated wiring are subject to resistance changes brought about by any variation in temperature. These videos illustrate some of the basics of using the APT System Software from both a non-programming and a programming point of view. Metal strain gauges have a gauge factor of about 2; thus, a strain of 0.1% will cause a 0.24 Ω change in a 120 Ω strain gauge. Response from Jeremy at Thorlabs: The ActiveX methods are described in detail under the APT Server Help file. This is partially due to the latency of the USB messaging scheme and partially a result of the relatively slow analogue to digital data conversion process that takes place inside the TSG001. Our legacy APT software allows the user to quickly set up complex move sequences with advanced controls made possible via the ActiveX, programming environment. One of the smaller projects that I took to Maker Faire last month was a strain gauge reading circuit for Arduino. strain gauge with Wheatstone bridge. Reportar. Click to EnlargeKSG101 K-Cube Kinesis Piezo Controller. Closed loop positioning can be achieved by using the KSG101 and KPZ101 together with the CA2906 SMA to SMA cable, which is not supplied with the KSG101 but is available separately. T, and two strain gages mounted on the bottom of the beam, labeled as a resistor C. These are wired to a strain indicator which will measure the strain of each gage, given by equation 4. The OLED display includes a backlight that can be dimmed or turned off using the top panel menu options. C#This programming language is designed to allow multiple programming paradigms, or languages, to be used, thus allowing for complex problems to be solved in an easy or efficient manner. A strain gauge is a device that measures electrical resistance changes in response to, and proportional of, strain (or pressure or force or whatever you so desire to call it) applied to the device. If you use channel A, you set the gain with switches 8,9, and 10. I have developped specific software under Excel VBA to pilot the four DC motor and to simultaneously acquire two strain gauges so I used active X control to developed my soft and I have noticed that strain gauge reading function (SG_GetReading()) is not able to work at 500Hz as specified on the help, in fact when I'm pulling on the get_reading function the maximum sampling rate available is just 5Hz(200ms). The enclosure is sealed to IP65 / NEMA 4 and a carry case option is available. It is the method SG_GetReading in the ActiveX control MG17Piezo.ocx. The bridge excitation voltage and INA333 reference voltage is supplied using the REF5025. TEDS works in a similar way in which USB computer peripherals immediately work as they are connected.
