    The DS201 pressure meter uses 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 a 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.

    IS-versions EX is intrinsically safe versions of this pressure meter for use in hazardous environments can also be offered.

    We are able to customise the DS201 pressure meter to suit your exact requirements if necessary whilst ensuring a minimal effect on price and availability.
