The GSV-11H is a measuring amplifier with analogue output for strain gauge full bridges.
In addition to the current output 4...20mA, voltage outputs 0.0...10.0V or 0.0V...5.0 volt are also available as an option.
The particular features of GSV-11H are
- the automatic zero adjustment across 2 mV/V (100% of the largest) of measuring range
- the low current consumption of just 38mA (plus output current),
- the optional amplification levels via jumpers, and
- the option to set the amplification in a continuously variable manner.
The zero adjustment is triggered by means of a control signal from the PLC or via a microswitch on the printed circuit board. The control level at the “tare” taring input should lie in the range of 10 volt to 30 volt.
The zero adjustment is triggered with the falling edge of a control level of at least 4ms at the tare input.
The GSV-11H is also available in another version as a printed circuit board (GSV.11L).
Even for a high input sensitivity of 0.5 mV/V, the range for the zero adjustment is a full 2mV/V so that even the smallest load changes are shown for a preload of e.g. 80% (magnify function).
The GSV-11H can supply up to 4 parallel weighing cells with a 350 ohm bridge resistance each and is therefore also perfectly suitable for applications in weighing technology.
