Submersible pressure transmitters

Turck has introduced the PT4500 and PT4510 submersible pressure transmitters, optimised for detecting the level of water or other media with similar density in challenging industrial environments - including in wastewater and irrigation systems, as well as tanks containing liquids such as gas and diesel.

Turck’s PT4510 submersible pressure transmitter is designed for low-level applications of up to 1 m, while the PT4500 is available in ranges up to 100 psig.

To deliver accurate level detection, a transmitter is placed at the bottom of the tank holding the liquid, and the transmitter then converts the pressure reading to an analog 4-20 mA output signal. The electrical connection to the transmitter is routed through the top of the tank and contains power and signal wires. It additionally includes a breathing tube that is used as a reference port to determine the atmospheric pressure outside of the tank.

These IP68-rated, stainless steel pressure transmitters may be used in industrial applications, as well as hazardous classified areas. The transmitters carry UL/cUL 913 approval for use in Class I, Division 1, Groups C and D locations when installed with an approved barrier, such as Turck’s IM33 series.
