Dwyer Instruments 616W Specifications

SERIES 616W | DIFFERENTIAL PRESSURE TRANSMITTER

®

FEATURES/BENEFITS

• NEMA 4X rated enclosure provides protection in harsh environments

permitting outdoor monitoring or in areas where dust and particulate
matter exists

• Easy to read LCD display provides immediate local alerts allowing

corrective action to be taken quicker to eliminate the problem from
becoming widespread

• Zero and span controls provides easy calibration checks and shorter

installation time to get device running and monitoring

APPLICATIONS

• Dust collection

• Outdoor HVAC

• Roof-top equipment

DESCRIPTION

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 then sending a standard 4-20 mA output signal. Design enables
operation in 2-wire current loops. A wide range of models are available factory calibrated

to specic ranges. The span and zero controls are for use when checking calibration. They
are not intended for re-ranging to a signicantly different span. The LCD display allows local

indication of pressure.
