Dwyer Instruments Inc. has announced the release of its new series EDPS ETL Listed Adjustable Differential Pressure Switch. The pressure switch is designed for pressure, vacuum, and differential pressures. The scaled adjustment knob allows changes to the switching pressure to be made without a pressure gage.

The EDPS is available with settings from 0.08in w.c. up to 16in w.c. The silicone diaphragm and PA 6.6 body make the Series EDPS suitable for use with air and other noncombustible gases. The Series EDPS can be used in monitoring air filters, ventilators, and industrial cooling-air circuits along with controlling air and fire-protection flaps and many other applications.

The compact size, adjustment knob and meeting the UL508 standard make the Series EDPS a suitable choice for HVAC applications.
