Critical Technical Advantages
-
High-Pressure Capability: The piezo-resistive metallic sensor allows the PMP21 to measure pressures up to 400 bar (6,000 psi). This makes it suitable for high-pressure hydraulic systems and gas storage applications where ceramic sensors typically reach their limit.
-
Extreme Compactness: Its small footprint is designed for installations where space is a critical constraint, such as in compact machinery, skid building, or dense piping manifolds.
-
Robust Material Quality: The device is constructed using high-quality 316L stainless steel for all wetted parts and the housing, ensuring durability against external environmental factors and internal process media.
-
Submersible Capabilities: With available ingress protection up to IP68, the PMP21 can be used in wash-down areas or as a submersible version for level monitoring in wells or sumps.
-
Broad Environmental Range: Operating reliably down to -40°C, it is well-suited for outdoor installations in cold climates or cryogenic gas monitoring (within the specified temperature limits).
-
Certified Safety and Traceability: The PMP21 supports plant safety requirements with international explosion protection certificates and marine approvals. It also offers optional EN10204 3.1 material certificates for full component traceability.
