DMD 331 Differential Pressure Transmitter for Liquids and Gases

Introducing the DMD 331: an advanced and versatile differential pressure transmitter designed specifically for industrial use. Built with a high-performance piezoresistive stainless steel sensor, this transmitter enables precise measurements in challenging environments. With the ability to handle both fluid and gas pressures, compatible with SST 1.4404 (316L) and 1.4435 (316L), the DMD 331 offers exceptional flexibility.

Its compact design allows for seamless integration into space-constrained machinery and applications. By accurately calculating the pressure difference between the positive and negative sides, this transmitter converts it into a proportional electrical signal, ensuring reliable and consistent readings. Experience exceptional performance and reliability with the DMD 331 differential pressure transmitter.

  • Range: from 20 mbar up to 16 bar
  • Outputs: 4 … 20 mA/ 0 … 10 V
  • Main Features: IS-Version Ex ia, permissible static pressure -onesided- up to 30 times of differential pressure range

Product Highlights

The DMD331 Pressure Transmitter is a versatile and high-performance device designed to measure differential pressure ranging from 0 … 20 mbar up to 0 … 16 bar. It offers 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 … 10 V. One of its special characteristics is its ability to handle differential pressure wet/wet applications. It can withstand a permissible static pressure (one-sided) of up to 30 times the range of the differential pressure. The transmitter boasts a compact design and is known for its mechanical robustness and reliability, even in dynamic pressure conditions as well as situations involving shock and vibration. Additionally, the DMD331 Pressure Transmitter offers various optional versions, including an IS-version (Ex ia) that ensures intrinsic safety for gases and dust. It also provides different electrical and mechanical connection options, catering to diverse customer needs.
