Product Description

The DMP 304 is specically designed for extreme high pressure and utilises a highly trusted foil strain gauge technology which is bonded to an all welded stainless steel 17-14PH sensing diaphragm.  This high pressure sensing assembly provides a mechanically robust construction to withstand hydraulic pressures up to 600 megapascals.

A choice of 3 high pressure hydraulic connections including metric and UNF female threads which rely on a internal metal to metal seal to provide a high integrity hydraulic seal.  A selection of standard universal electrical connections of DIN and Binder are available for compatibility with most electrical installations.

The DMP-304 has a 4-20mA with or without IS approval output signal for transmitting the measured hydraulic pressure.  To aid calibration, zero and span adjustment screws are provided to tare zero reading and adjust gain over the service life of the transducer to ensure more precise hydraulic measurements.
