Siemens pressure transmitter P320/420
The SITRANS P320/420 pressure transmitters are the first to offer remote safety handling. This allows users to program all devices directly from the control room, rather than configuring each individual transmitter on-site. This streamlines the commissioning process, especially for applications requiring functional safety. Additionally, the extended test period of up to 15 years, compared to the usual 2 years, helps ensure low maintenance costs.
