Ensure cargo tank safety with the DMP 331 SIL2 approved pressure transmitter. Intrinsically safe for hazardous environments, this sensor accurately measures both vacuum and positive pressure in inert gas systems.
The DMP 331 pressure transmitter is a crucial component in maintaining the safety and integrity of cargo tanks, particularly those carrying flammable liquids. These tanks utilize inert gas systems to prevent the formation of explosive atmospheres within the tank. To ensure safe operation, it’s essential to meticulously control the pressure within these tanks, preventing it from exceeding safe limits. The DMP 331 is specifically designed to monitor this pressure, accurately measuring both vacuum and positive pressure relative to atmospheric pressure. This dual measurement capability eliminates the need for separate sensors, simplifying installation and reducing costs.
A key feature of this version of the DMP 331 is its intrinsic safety approval for hazardous environments. This certification, combined with a Zone IS barrier, allows for safe operation in areas where flammable gases or vapors may be present, such as cargo tanks containing volatile liquids. The sensor’s electronics are SIL2 approved, providing a high level of reliability and functional safety, which is critical in preventing accidents and ensuring the integrity of the inert gas system.
The robust construction of the DMP 331 ensures long-term reliability and performance in demanding marine environments. The use of 316L stainless steel for both the process connection and the diaphragm provides excellent corrosion resistance, extending the sensor’s lifespan and reducing maintenance requirements. The FKM seals offer broad chemical compatibility, making the DMP 331 suitable for a wide range of cargo types.
This pressure transmitter is commonly employed on tankers, barges, and other vessels transporting flammable liquids, as well as in shore-based storage facilities. Its compact design and variety of process connections make it adaptable to different tank configurations and installation requirements. The 4-20mA output signal allows for easy integration with existing control systems, providing real-time pressure data for monitoring and automated control.
