DMP 331 P Pressure Transmitter Core Product Features
The DMP331P Pressure Transmitter offers a versatile solution for pressure measurement across a wide range of applications. With a nominal pressure range starting from 0 … 100 mbar and going up to 0 … 40 bar, it ensures accurate and reliable readings. The transmitter provides output signals in both 2-wire (4 … 20 mA) and 3-wire (0 … 10 V) configurations, with the flexibility to accommodate other signal options upon request. One of its notable features is the availability of a hygienic version, making it suitable for use in industries with strict cleanliness requirements. The diaphragm of the transmitter boasts low surface roughness, ensuring precise measurements and reducing the risk of contamination.
Additionally, the DMP331P can be subjected to CIP (Clean-In-Place) and SIP (Sterilise-In-Place) cleaning processes at temperatures of up to 150 °C. It is also capable of withstanding vacuum conditions. Optional versions of the transmitter include an IS-version (Ex ia) that is intrinsically safe for gases and dust, a SIL 2 version compliant with IEC 61508 / IEC 61511 safety standards, a diaphragm made of Hastelloy® or Tantalum for enhanced chemical resistance, and a cooling element designed to handle media temperatures of up to 300 °C. Overall, the DMP331P Pressure Transmitter combines precision, adaptability, and advanced features to meet the diverse needs of pressure measurement applications.
Applications
In the food and beverage industry, the DMP 331 P Pressure Transmitter is used to monitor and control pressure in processes where hygiene and cleanliness are critical. Its flush stainless steel diaphragm prevents product residues from accumulating, which is essential for maintaining sanitary conditions during the production of items like dairy products, beverages, and processed foods. The transmitter’s design allows for easy cleaning and sterilization, supporting compliance with strict food safety regulations and ensuring that the final products are safe for consumption.
For the pharmaceutical industry, the DMP 331 P is applied in environments where precise and reliable pressure measurement is vital for product quality and safety. Pharmaceutical manufacturing often involves processes such as mixing, filtration, and filling, all of which require accurate pressure control. The transmitter’s robust and hygienic construction allows it to withstand aggressive cleaning agents and sterilization procedures, making it suitable for use in cleanrooms and other controlled environments. This helps pharmaceutical companies maintain the purity and consistency of their products while meeting stringent regulatory standards.
