General Description

Ideal for jockey pumps, air compress, and fire pumps, the model ADPS is an Adjustable Deadband Pressure Switch with independent set and reset points which are adjustable throughout the entire operating range of the switch.  The minimum deadband (minimum span between set and reset points) may be obtained at any point in the operating range of the switch.  A change in pressure greater than the high setting will reposition the switch mechanism to open or close a single snap-action electrical switch.

This control device is designed for use as an operating control in applications sensing air, water, or any fluid not harmful to the pressure connection, diaphragm or nitrile pressure-sealing o-ring.  Where an operating control would result in personal injury and/or loss of property, it is the responsibility of the installer to add devices (safety, limit controls) that protect against, or systems (alarm, supervisory systems) that warn of control failure.

This device is not intended for applications in explosive environments or use with hazardous fluids.

Construction:
  • NEMA Type 4X Enclosure for indoor or outdoor use. (To maintain 4X rating, use appropriate Type 4 conduit hub.) 
  • Forged Brass or 316S.S. Pressure Connections (1/2 HP Brass only)
  • Aluminum Diecast Base with Polymer Enclosure
  • Beryllium Copper Diaphragm (Stainless steel isolator diaphragm included for protection of beryllium copper diaphragm on models with stainless steel pressure connection.)
  • Nitrile Pressure Sealing O-ring

Switch Contact:  Snap-Action SPDT (Form C)     

  • 15 Amps @ 125/250/480 VAC

DPS-50

$169.99 EACH

UL listed and CSA Approved

Maximum Rated Pressure:  250 PSI

Maximum Working Pressure:  180 PSI

Pressure Connections:  Brass 1/4-18 NPT Female

General Description

The Model DPS-50 is a differential pressure switch used to monitor the difference in pressure between two pressure sources.  A change in pressure between the high and low pressure ports greater than the differential pressure setting (8-50 PSID range) will reposition the switch mechanism to open or close a single electrical circuit by means of a snap-action electrical switch.  This control device is designed for applications sensing air, water or any fluid not harmful to brass or silicone and not classified as a hazardous fluid.

This control device is designed for use only as an operating control.  Where an operating control failure would result in personal injury and/or loss of property, it is the responsibility of the installer to add devices (safety, limit controls) that protect against, or systems (alarm, supervisory systems) that warn of control failure.

Ambient Temperature Range:  -40/180F (40/82C)

Media Temperature Range:  32/250F (0/121C)
