Page 4: Description
Description The GSV-1 is a precise bridge amplifier with an analog output for strain gage full bridges. The special feature of the GSV-1 is the automatic zero balancing within just 90 milliseconds across 100% of the measurement range. The zero balancing is triggered by means of a control signal from the PLC or with a pushbutton. -

Page 7: Top Hat Rail Housing Gsv-1H
Top hat rail housing GSV-1H The measuring amplifier GSV-1H is available with voltage outputs ±5V, ±10V and current output 4...20mA. The force sensor is connected to terminals 1 to 4. The voltage supply (11-28V) is connected to terminal 5 and 8 (ground). For zero setting, terminal 6 is connected to the mains supply or a control signal between 5 and 24 volts is applied. -
Page 8: Adjustment Of Input Sensitivity
Adjustment of Input Sensitivity Input sensitivity can be adjusted by relocating the jumper. Input sensitivity for position 1 is given in the type designation. With position 5 amplification can be adjusted continously by the trimmer "TR". Position Amplification Output voltage at sensitivity Output voltage at sensitivity factor option 2 mV/V... -
Page 9: Top Hat Rail Housing Gsv-1Hsw
Top Hat Rail Housing GSV-1HSW The measuring amplifier GSV-1H is equipped with a voltage output and a current output. It is provided with two threshold switches with a relay and a very fast peak value storage for signals up to 2.5kHz (optionally 10kHz) The bridge excitation of the measuring amplifier (terminal 1 and 2) is connected with the sensor input. -
Page 10: Functional Diagram
hysteresis is 2.5% of the measurement range. At outputs F1 and F2 voltages of 0.03 volts up to 1 volts are detected. Below the switching thresholds the relays are in the working state, the relay contacts are opened. The corresponding light-emitting diodes (LED) light below the switching thresholds. -
