Baumer’s pressure transmitter PFSX with SIL2 certification (Safety Integrity Level 2) has been developed according to the IEC 61508 standard. It is suitable for water treatment and energy generation applications as well as for applications in the chemical, petrochemical, pharmaceutical, and food & beverage industries. The measuring instrument comes with a 4…20 mA analogue output and two galvanically insulated relay outputs with integrated test functions for alarm purposes.
The PFSX can measure pressure ranges from 0…1 up to 0…400 bar with an accuracy of ±0.5 % of the full scale. The pressure transmitter has a four-digit red LED display (8 mm high) with two set points. It is fully programmable on site without any additional tools. All parameters are password-protected.
This approval is based on the Safe Failure Fraction (SFF) of 98 % and the Hardware Fault Tolerance (HFT) which is 0. The sensor architecture guarantees SIL2 safety without the need to use two pressure switches to ensure redundancy. For applications in hazardous areas, the transmitter is also available in ATEX Ex ia IIC T5/T6, ATEX II 1G versions.
The IEC 61508 standard defines basic safety requirements, both for the regular system operation and for the predictability of a failure. These requirements cover general safety management systems, specific product design and safety-compliant process design with the aim of avoiding both systematic design faults and random hardware failure.
