Pressure Switches

United Electric Controls (UE)

Pressure switches, manufactured by United Electric Controls (UE), are designed for rugged, industrial and hazardous environments. Our pressure switch products measure pressure in applications ranging from hazardous locations, corrosive atmospheres and explosion-proof areas. Many of our products principally perform alarm and shutdown functions, while others provide critical sensor inputs into control systems. We supply a broad line of pressure switches from the simple skeleton frame type for OEM applications to legacy electromechanical products, as well as state-of-the-art full digital field configurable pressure switches.

If you need to replace your mechanical pressure switches and your customers are struggling with Management of Change (MoC) requirements, then this is a must-read for you and your customers.

One Series Pressure Switch

One Series
Pressure Switch for Hazardous Locations
With an integral solid-state relay, the One Series can do much more than a typical process transmitter! In addition to monitoring the process, the application may call for providing an alarm or shutting down a pump or compressor, even actuating a valve. The One Series 1XSW electronic switch drops in place of any mechanical pressure or temperature switch that is connected to the plant control system, PLC or DCS, including 24 VDC, 48 VDC, 120 VAC, 125 VDC and 230 VAC inputs.
