IQ Sensor Net System WTW IQ Sensor Net EX-Isolated Amplifier

Overview Specifications Documentation & Tools


The WTW IQ Sensor Net EX-Isolated amplifier is installed outside the zone and supplies the monitor within the zone with it's own intrinsic power circuit. In addition, it transfers the meaured value via an mA output or via HART (optional).

Product Features
  • Supplies the monitor with auxiliary energy and transfers the measured value
  • Can be integrated with WTW IQ Sensor Net System
  • Highest safety, even at high ambient temperatures
  • Safe separation and isolation of input, output and auxiliary power
  • Can be connected to the IQ SENSOR NET

The WG 21 is also available with a 24 V AC/DC auxiliary voltage and can therefore be integrated into the IQ SENSOR NET.
