With a product range of over 1,000 designs and strain gauge measurement technologies including weight measurement, force measurement, temperature, pressure, voltage, current, potentiometer, rate, flow, LVDT, displacement, inclination, vibration and torque in either analogue, digital or wireless technologies. Basic working principle of strain gauges : In 1856, Kelvin observed that resistance of the conductor is directly proportional to the length and inversely proportional to the area of the conductor. capabilities of instruments for strain measurement are not static but tend to develop over time. Because the modular plug is attached to the end of the leadwire, neither soldering nor screwing is necessary when connecting the strain gauge to a measuring instrument. Strain gauge, device for measuring the changes in distances between points in solid bodies that occur when the body is deformed.Strain gauges are used either to obtain information from which stresses (internal forces) in bodies can be calculated or to act as indicating elements on devices for measuring such quantities as force, … Board Flexure 8 Intel® Manufacturing Enabling Guide March 2016 Strain can be calculated by: ε = ΔL / L1 This value is dimensionless (the units of length cancel out). For example, suppose a test specimen undergoes a substantial strain of 500 µε. 4-wire strain measurement method. For isotropic materials, stress distributions are measured from the strain distributions. Strain measurement systems ZETLAB data acquisition modules can be connected to any kind of strain sensors (torque sensors, compression sensors, tensile and compression sensors, resistive strain gauges, etc.) force). To measure strain, virtual strain gauges are placed at each edge of a triangulated measurement grid. A cantilever beam was loaded at the tip, and data was recorded from base-mounted strain gages. Whether it is a noninvasive flow sensor for medical device manufacturers, a rugged pressure sensor for oil and gas exploration, or a miniature load cell for aerospace applications, our customers need the utmost … In this project, students will use methodologies outlined in the previous labs to design and implement their own strain measurement system for a given measurement need..
