DMP 331 Industrial Pressure Transmitter for Low Pressure

The DMP 331 precision pressure transmitter is based on a silicon strain gauge sensing device with media Isolated diaphragm. This offers high repeatability and low-pressure hysteresis measurements. A thin stainless steel membrane and the internal oil filling separate the media from the silicon chip, meaning the sensor can be used with non-corrosive gases and liquids.

Product Highlights

The DMP331 pressure transmitter is a versatile and reliable device designed to accurately measure pressure in a wide range of applications. It offers a nominal pressure range from 0 … 100 mbar up to 0 … 60 bar, providing flexibility for various pressure requirements. The transmitter offers two output signal options: a 2-wire configuration with a 4 … 20 mA signal and a 3-wire configuration with a range of 0 … 20 mA or 0 … 10 V. Additionally, the transmitter can be customised to accommodate other output signals upon request. One of the standout features of the DMP331 is its perfect thermal behaviour, ensuring accurate measurements even in varying temperature conditions. It also boasts excellent long-term stability, ensuring consistent performance over time. The pressure port is designed with a flush G 1/2″ connection from 100 mbar, allowing for precise measurements in applications where a flush mount is necessary. The DMP331 offers optional versions to cater to specific needs, such as an IS-version for intrinsic safety in gas and dust environments, SIL 2 compliance according to IEC 61508/IEC 61511, a welded pressure sensor, and customer-specific versions for specialised requirements. Overall, the DMP331 pressure transmitter combines reliability, flexibility, and advanced features to meet the demands of diverse industrial applications.
