P320/420 siemens Differential Pressure Transmitter

P320/420 siemens Differential Pressure Transmitter are the first pressure transmitters with remote safety handling: It enables the user to program all devices from the control room instead of each individual transmitter on site. This shortens commissioning, especially in applications that require functional safety. A test period of up to 15 years instead of the usual 2 years ensures low maintenance costs.
