JUMO SIRAS P21 AR
Process pressure transmitter with SIL/PL
The pressure transmitter reliably and accurately measures relative and absolute pressure of liquids, steam, and gases. It was developed for use in safety-related plants with Safety Integrity Level (SIL) according to DIN EN 61508. As a result, the transmitter is perfectly suited for safety measuring chains in the process industry and mechanical engineering.
