Ssiemens 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.

Benefits

• Reduced commissioning time due to remote safety handling
• Suitable for harsh conditions due to robust materials
• User-friendly due to clear and large display and diagnostic icons acc. to NAMUR NE107 and a quick start wizard
• Maintenance cost reduction due to proof test interval up to 15 years
• Fast reaction and optimized processes due to reduced response timeAccuracy? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 0,065 % (SITRANS P320), 0,04 %
