The SITRANS P320/420 pressure transmitters are the first to feature remote safety handling capabilities. This allows users to program all devices directly from the control room, rather than having to configure each individual transmitter on-site. This streamlines the commissioning process, particularly for applications requiring functional safety. Additionally, the extended test period of up to 15 years (compared to the typical 2 years) helps to minimize maintenance costs.
