Dwyer Differential Pressures Transmitter

616W Dwyer Differential Pressures Transmitter

616W Dwyer Differential Pressures Transmitter (Positive, negative, and differential pressures) can be measured within a full span accuracy of ±0.25 with the Series 616W Differential Pressure Transmitter. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases and then sending a standard 4-20 mA output signal. Design enables operation in 2-wire current loops. A wide range of models is available factory calibrated to specific ranges. The span and zero controls are for use when checking calibration. They are not intended for re-ranging to a significantly different span. The LCD display allows local indication of pressure.
