3051 HART Smart differential pressure transducer 4-20mA capacitive pressure transducer
Description of 3051 HART Smart differential pressure transducer 4-20mA capacitive pressure transducer
3051 HART Smart differential pressure transducer 4-20mA capacitive pressure transducer is based on the use of the world's advanced, mature and reliable capacitive sensor technology, combined with advanced single-chip computer technology and sensor digital conversion technology designed to be multi-functional digital • Intelligent meter..
The differential pressure transmitter is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. Outputs a 4~20mADC signal corresponding to the measured differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via HART communications. Other key features include quick response, remote set-up using communications, self-diagnostics and optional status output for pressure high/low alarm.
