Model WGT-420 Differential Pressure Transducers
Differential Pressure Transducers Model WGT-420 have been developed primarily for HVAC and similar applications. Model WGT-420 Differential Pressure Transducers convert a differential or gauge air pressure signal to a 4-20 mA signal.
The new silicone sensor offers excellent performance characteristics at a low cost. A signal conditioning circuit runs as a two wire 4-20mA device.
The input pressure signals are mechanically dampened to reduce sensitivity to turbulence and short duration pressure fluctuations.
Integral zero and span adjustments are factory calibrated to specified output signal levels and may be field adjusted if required. The circuit design produces very little interaction between span and zero pots.
Differential Pressure Transducers Model WGT-420 typical applications include HVAC monitoring of filter differential pressures, fan static pressures, clean room pressures, variable air volume systems and velocity pressures.
