New DMP304 ultra-high pressure transmittersImpress Sensors & Systems is launching the DMP304 ultra-high pressure transmitters that are suitable for a wide range of high-pressure applications, including hydraulic circuits, water jet spraying and other high-pressure chemicals, pharmaceuticals, oil, gas and petrochemical applications.

The design of the DMP304 ultra-high pressure transmitter is based on a compensated strain gauge, bonded onto a stainless steel diaphragm. With its rugged, stainless steel housing, the sensor offers a maximum nominal pressure of 6000bar, making it suitable for use in a variety of harsh, high-pressure industrial applications.

Sam Drury, the Sales & Marketing Director at Impress Sensors & Systems, comments: "The DMP 304 is ideal for applications where the customer is looking for a robust, high-precision, high-reliability pressure transmitter that also offers very high nominal pressures. A version of the sensor is also available for intrinsically-safe, hazardous gas and dust applications."

Special characteristics of the sensor include the ability for the user to adjust the offset and span (difference between FSO and zero) via front-sided potentiometers. This means engineers can take out sensor drift or any residual pressures in the system and scale the output to their preferred pressure range.

The DMP 304 is accurate to 0.5 per cent FSO according to IEC 60770. An optional 0.25 per cent FSO version is also available. For users wishing to calibrate the transmitter after installation, an MIL/Bendix connector plug option is supplied as standard, enabling shunt calibrations to be carried out, simulating up to 80 per cent of FSO.

DMP 304 transmitters are available in nominal pressure ranges from 0-2500bar up to 0-6000bar. Output signal is two-wire, 4-20mA or a three-wire 0-10V version is available on request. The response time of the sensor is less than 2.5ms.
