Q&A

Q1: What is the pressure measurement range of the PMP51-BA21JA1SGBRKJA1+AA?

A: This transmitter is configured with a sensor cell capable of measuring 0 to 400 bar (0 to 6,000 psi) gauge or absolute pressure . The "S" in the order code corresponds to the 400 bar sensor cell. It can withstand an overload limit of 600 bar (9,000 psi) without damage .

Q2: What are the accuracy specifications for the Cerabar PMP51 series?

A: The standard Cerabar PMP51 provides ±0.1% reference accuracy . For applications requiring higher precision, a "Platinum" version with ±0.075% accuracy is optionally available . The device also features excellent long-term stability of less than 0.1% of URL per year .

Q3: Is the Cerabar PMP51 suitable for use in safety instrumented systems and hazardous areas?

A: Yes. The PMP51 series is SIL2 certified according to IEC 61508 and IEC 61511, making it suitable for process pressure monitoring in safety instrumented systems . Additionally, the "B" approval code in this model indicates ATEX/IECEx Ex ia certification for intrinsic safety in hazardous (explosive) areas
