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. The control levels may be in between 3.5 and 30 volts.

The GSV-1 is available in many housing variants and many options, e.g. threshold value 
sensor, peak value store, amplification selection by means of jumpers, stepless 
amplification adjustment, plug connections etc.

The maximum range for the zero balancing is 100% of the sensitivity range with an output 
signal ±5V at the GSV-1L. The GSV-1L with an output signal 0-10V is the zero balancing 
±50% of the sensitivity range.

With options GSV-1H and GSV-1A the zero balancing accounts for ±100% of the nominal 
sensitivity in every amplification level (2mV/V or 3.5mV/V).
The range for the zero balancing does not get reduced when the amplification is 
increased.
 
The GSV-1 can supply up to 4 parallel-connected weighing cells with 350 ohm bridge 
resistance each and is therefore eminently suitable for applications in weighing 
technology. The option GSV-H can supply for 8 weighing cells with 350 ohm bridge 
resistance.

Die Leiterkarte GSV-1L misst nur 30mm x 40mm x 6,5mm und kann aufgrund der 
Stiftleisten leicht als Aufsatz in größere Leiterplatten integriert werden.

The GSV-1L printed circuit board measures just 30mm x 40mm x 6.5mm and can easily 
be integrated as an add-on in larger PCBs thanks to the the pin strips.

The top hat rail housing GSV-1H for mounting rails according to EN50022 is just 12.5mm 
wide and 114.5mm long. 

The measuring amplifier GSV-1HSW additionally contains two threshold value sensors 
with a relay and a peak value store. The thresholds are set either from front-side spindle 
trimmers or connectable remote potentiometers.

The measuring amplifier GSV-1A has a robust aluminum pressure-cast housing in 
environmental protection rating IP66. There is a light cast-plastic housing GSV-1M in IP66 
available for portable applications. 

For multi-channel applications for stress analysis with strain gages, in addition, we also 
offer affordable 8-channel devices with analog outputs.
