HT BHZ93420-III SEREIES LIQUID LEVEL TRANSMITTER WITH HART AGREEMENT
BHZ93420 III Liquid level Transmitter
Introduction:
BHZ93420-III insertion-type intelligent liquid level transmitter is equipped with a high-precision piezoresistive silicon pressure sensor as its signal measuring element. It measures the static pressure, which is directly proportional to the liquid level. The transmitter utilizes HART communication protocol to achieve digital signal transmission and two-way communication.
The LED/LCD display input liquid level transmitter should be coated with functions including liquid level value, alarm status, working status, unit switching and configuration parameters, so that users can intuitively understand and operate the liquid level transmitter
