Pressure Transmitters & Sensors

Truly Uninterrupted Display

Equipped with a cinema-grade LED display you’ll have to see to believe, along with a reading that will change from Green to Red when a Relay is active.

Pressure Transmitter Relays allow the user to stop or start pumps and alarms when the pressure hits set relay points. Get visual indication when it is time for a filter or strainer change out and protect all elements of your pipping system.

Wide Range of Options

Find the perfect fit for your application. Along with local display or blind units, we can offer our sensors with ceramic, Teflon^® or stainless diaphragms, as well as various end connections.

Pressure or Level Measurement

In some applications where Level sensors cannot be installed in the top of a tank, pressure transmitters have the ability to also measure tank level.
