The Argus Digital Pressure Switch - The Next Generation of Pressure Control

The Argus Digital Pressure Switch is the next generation of pressure control at the wellhead.

The DPS provides on or off control to your artificial lift pumps in the event of a Hi or Low pressure fluctuation. The DPS utilizes an interactive digital display for precise and real time pressure monitoring and control. With a 4-20 mA feedback you can now identify what the wellhead pressure is remotely.

Two independent relays and a 99 second variable delay provide flexibility like you have never had before.

Pressure Switch, Gauge and Transmitter all in one rugged device built to be installed at the wellhead.


  • Ability to program dual high and low set points
