BHZ93420III Stainless Steel Hart Agreement High Precision Intelligent Liquid Level Transmitter
BHZ93420 III Liquid level Transmitter
Introduction of water level transmitter:
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.
intelligent liquid level transmitter typically support a variety of output modes, including analog signals (such as current or voltage), digital signals (such as RS485 or Modbus), and wireless communications (such as Wi-Fi or LoRa). This can meet the requirements of different application scenarios. The intelligent liquid level transmitter has built-in data processing and analysis function, which can process, calculate and analyze the liquid level data. For example, liquid level trend analysis, alarm Settings and anomaly detection can be performed
