      Is the sensor defective?

      Instructions for troubleshooting for sensors with strain gauge

      • Test the Sensor without amplifier by measuring:
        • Measure the input resistance and compare the measured value with the value in data sheet; Measure the resistance between +Excitation and -Excitation; typical values ​​of sensors with Straingages are 350Ohm, 1000Ohm, 370Ohm, 390Ohm, 700Ohm
        • Measure the output resistance and compare it with the value in the data sheet; Measure the resistance between +bridge output and - bridge output; typical values ​​of sensors with straingages are 350Ohm, 1000Ohm, 700Ohm;
        • Measure the insulation resistance. Measure the resistance between bridge output and sensor housing. The resistance should be greater than 200 MOhm.
      • Connect sensor to amplifier and switch on
        • Supply voltage measured between +Excitation and -Excitation. Typical values ​​are 2.5V or 5V or 10V or 8.75V
        • Measire the differential voltage at the bridge output (select multimeters range "mV"). Typical values ​​are -1mV to + 1mV. If a value of the order of 10mV is measured, then the sensor is probably overloaded. If a value of half the supply voltage is measured, then within the sensor is a cable break.
