Model: 3144PD1A1E5B4M5 Rosemount 3144P temperature transmitter with HART protocol and FOUNDATION fieldbus protocol FF 3144P temperature transmitter has excellent accuracy, stability and reliability, making it a control / security applications industry-leading temperature transmitter. It accepts a single sensor and dual-sensor input. This dual-sensor input function allows the transmitter to accept input from two independent sensors. Dual-sensor configuration can be used to measure temperature, average temperature or for redundant temperature measurement. 3144P (Hart) by the IEC61508 safety instrumented system certification. Transmitter with stability up to five years, ranking the same industry-leading level. Dual hot backup sensor if the primary sensor fails, the measurement system automatically switches to the backup sensor, the risk of losing important temperature measurements gradually lower 80%.
