Technical overview

Grundfos Direct Sensors™, type RPI, is a series of

industrial strength relative-pressure transmitters

designed to be mounted directly on the unit, for

example a pump. In addition to pressure, the RPI+T

version is able to measure temperatures ranging from

0 to 100 °C.

The RPI has a standard M12 connector.
