JFA712C Monocrystalline Silicon/ Differential Pressure Transmitter
JFA712C differential pressure transmitter: which have a very high anti-interference andstability.
and the digital compensation technology is used to compensate the temperature and static
pressure, which improves the measuring accuracy and reduces the temperature drift.
The features of the transmitter are the good long-term stability, the high reliability
and the diagnosis ability, etc. In structure, the configuration, setting up
and calibration of transmitter are easy for the users by the HART communication
handhold terminal, the knobs of outside shell and the buttons on the display.
Small size and light weight.
Range migration function, the range migration ratio is 100:1.
Damping: 0~32s can be adjusted, step to 0.1s.
Zero point, full scale compensation revision function.
Multi-point calibration of output current.
Multiple monitoring variables be shows, pressure unit can be choose.
Ultralow temperature OLED displayer.(-40~70℃).
Output current root square function.
Self-diagnosis and fault alarm;
The EEPROM nonvolatile memory prevents the loss of data and recovers the original calibration data;
The remote, on-site parameter setting and function configuration are realized
through the HART communication hand operator.
Liquid, gas and steam
