Pressure transmitter for harsh environment
The Rosemount 3051S pressure transmitter has been enhanced to allow measurement possibilities in high process temperatures or changing ambient conditions. The 3051S thermal range expander with Ultratherm 805 oil fill fluid enables pressure measurements by direct mounting a diaphragm seal system to processes that reach up to 410 °C without requiring the challenging impulse piping or heat tracing used in traditional connection technology. In applications where ambient temperatures drop below ideal operating conditions, system response time becomes slow, resulting in delayed process pressure readings. By using the thermal range expander dual fill fluid seal, reliable pressure measurements at low ambient temperatures are also possible. Moreover, the Rosemount 3051S Electronic Remote Sensors (ERS) system has safety certification. The ERS System calculates differential pressure through a digital architecture – and is suitable for SIL 2 and SIL 3 applications.
