Strain gauge: The electronic component that will change its resistance while its length has changed. Strain gauges are used in the FMS force sensors for acquisition of the feedback value. 3 System Components The EMGZ306A consists of the following components (refer also to Fig. 1): Force sensors •... -
Page 5: System Description
Due to the wheatstone wiring of the strain gauges, the measured value is according also to the power supply. So, the force sensors are supplied from the EMGZ306A by a very accurate power supply. -

6.6 Calibrating the Measuring Amplifier without a Weight (EMGZ306A.CAL only) The EMGZ306A.CAL has a calibration button on the front side. Pushing this button simulates an input of 4.5mV at the amplifiers. This is used as reference point for the calibration without weight. - Page 13 The Gain Calculator is a tool for easy weightless calibration of FMS digital amplifiers and FMS analogue amplifier EMGZ306A.CAL. 1. First go through step 1 to 4 in the FMS-calculator and fill-in all relevant data. 2. Choose the appropriate sensor type.
