SITRANS P320/420

USA - SITRANS P320/P420

Smart pressure transmitters

SITRANS P320/420 digital pressure transmitters are the first 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. Both pressure transmitters have an increased proof test interval over other devices on the market, with testing periods of up to 15 years rather than every two. Your result: significantly lower maintenance costs.
