Product Highlights

The DMK331 offers a nominal pressure range from 0 … 400 mbar up to 0 … 600 bar. It provides two output signal options: a 2-wire configuration with a range of 4 … 20 mA, and a 3-wire configuration with a range of 0 … 20 mA or 0 … 10 V. Customised output signals can be accommodated upon request. One of its special characteristics is the pressure port G 1/2″ flush design, which is specifically suited for handling pasty and polluted media. This ensures accurate pressure measurements even in challenging environments. Additionally, it features a pressure port G 1/2″ open port made of PVDF, which enables compatibility with aggressive media. This allows for reliable pressure readings in applications involving corrosive substances. Moreover, this pressure transmitter offers an optional oxygen application version, making it suitable for use in oxygen-rich environments. For specific requirements, the transmitter is available in various optional versions. The IS-version (Ex ia) is intrinsically safe and designed for gases and dusts. It complies with the SIL 2 standards according to IEC 61508 / IEC 61511, ensuring high safety integrity. Furthermore, the DMK331 can be customised to meet customer-specific needs, providing flexibility and adaptability to different applications
