Hart protocol pressure transmitter

Specifications

Combine the modern digital chip technology on basis of metal capacitive transmitter. High accuracy, long-term Stability.

Brief introduction:

RP61 smart pressure transmitter is a new product developed by VIRVO Company which combines the modern digital chip technology on basis of metal capacitive transmitter. The signal conversion of sensor use isolated digital capacitive electro circuit to replace the traditional analog signal amplification electro circuit and A/D converting circuit; besides VIRVO Company make use of digital compensation technique to compensate the temperature and static pressure, thus improving the measurement accuracy, reducing temperature drift. Our transmitter has the advantage of long-term stability, high reliability and strong self-diagnostic capacity. It is mainly used for measuring the absolute pressure and gage pressure. And the RP61 is divided into two kinds:RP61-G for measuring gage pressure and level, RP61-A for measuring the absolute pressure, both of them adopt the composite silicon sensor.
