SITRANS P320/420
Process Instrumentation
Pressure Transmitter
SITRANS P320/420 is the first pressure transmitter on the market to feature remote safety handling. The instruments’ remote safety handling via SIMATIC PDM saves time during SIL commissioning: rather than manually programming each individual device across a facility, operators can access transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. Both pressure transmitters have an increased proof test interval over other devices on the market with testing periods of up to fifteen years rather than every two. This lowers maintenance costs significantly.
