CYW12CY Protective Submersible Level Transmitter 4-20mA HART RS485 Accuracy 0.25%FS 0.5%FS
CYW12CY Protective Submersible Level Transmitter Range 0~1~200mH2O Output 4~20mA HART RS485 Accuracy 0.25%FS 0.5%FS
This level transmitter product adopts stainless steel double isolation diaphragm OEM pressure sensor as the signal measurement element, the internal sealing treatment, the external use of the integral laser welding process, so that it has the function of anti-condensation in the cavity, and after automatic computer testing, the laser resistance process is used for a wide temperature range of zero point and sensitivity temperature
Compensate. It is anti-interference, small temperature drift, high stability, and has high measurement accuracy, which is an ideal liquid level measuring instrument in the field of industrial automation.
