Description

The DS201 pressure meter is a pressure switch with a 4 digit LED display providing a local digital readout of the measured pressure.

As standard, the DS201 pressure meter features 1 PNP contact and rotatable display for easy reading in awkward installations. 2 independent and 4 independent PNP contacts can be offered, which are freely configurable.

A wide variety of electrical connections and mechanical connections are available, including flush pressure ports for pressure measuring in highly polluted, viscous and pasty media.
