Benefits Introduce In Detail

Hydrostatic pressure transmitter for level detection applications

The ifm PS3 series hydrostatic pressure transmitter can indicate the liquid level pressure in tanks, containers, pits, and wells.

This 2-wire stainless steel transmitter can be directly immersed into the medium to provide a 4…20 mA analog signal. Its polyurethane waterproof vent tube cable can withstand over 220 newtons of force. The transmitter measures the liquid level through the principle of static pressure. The weight of the liquid applies pressure to the transmitter’s measuring element. As the liquid level changes, the output also changes. The transmitter’s accuracy reaches 0.5% of the full scale, and its repeatability is 0.1%, ensuring very high operational reliability.

Models with selectable measuring ranges of 0.25 bar, 0.6 bar, and 1 bar are available, as well as various cable lengths.

Leveraging analog output signals, 2-wire technology, and a wealth of accessories, it can be easily integrated into existing applications.
