Description
- Wide no-load zero adjustment range (±2 mV/V)
- High/low limit comparators
- Indicated value is output in a voltage range of 0 to 10 V or in a current range of 4 to 20 mA.
- Up to 4 transducers with 350 Ω bridge resistance connected in parallel.
The WGA-650B is an Instrumentation Amplifier which can display the physical quantity of an input sensor.
It is compact and moderate price.
