    Strain gauge: 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 EMGZ300 consists of the following components (refer also to fig. 1): Force sensors •...

  • Page 5: System Description

    The force sensors measure the tension force in the material and transmit the measuring value as a mV signal to the hybrid module in the electronic unit EMGZ300. The electronic unit amplifies the mV signal depending on configuration. The resulting feedback value can be transmitted to an analog instrument, a PLC or equivalent devices.

    Operating manual EMGZ300 6.3 Wiring fig. 4: Wiring diagram E300004e There can be connected 1 or 2 force sensors to each channel. Using 2 force sensors in 1 channel, the connection cables will be wired parallel. The output signal of the measuring amplifier then will correspond to the average value of the 2 sensors.

    Operating manual EMGZ300 7.3 Configuring the outputs Each channel provides a tension output (±10V) and a current output (0...20mA resp. 4...20mA) which are active simultaneously. The signal of the current output is configured as follows: Current output 0...20mA The jumpers will be set to „0...20mA“ (fig.
