SITRANS P320/420

SITRANS P320/P420 pressure transmitters are digital pressure transmitters featuring extensive user-friendliness and high accuracy. The parameter assignment is performed using input buttons or the HART interface.

The comprehensive functionality makes for precise adjustment of the pressure transmitter to the requirements of the plant. Operation is very user-friendly in spite of the numerous setting options.

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 attending to each individual device across a facility, operators can program transmitters from the control room. This reduces the commissioning time in applications requiring functional safety. What´s more 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 they are lowering maintenance costs significantly.
