BHZ93420-III 3051 Cast Aluminum Alloy RS485 Digital Water Level Transmitter
BHZ93420 III Liquid level Transmitter
Introduction of water level transmitter:
The BHZ93420-III insertion-type intelligent liquid level transmitter is designed with a high-precision piezoresistive silicon pressure sensor as its signal measuring element. The sensor measures the static pressure, which is proportional to the liquid level. With the HART communication protocol, it achieves digital signal transmission and two-way communication. This transmitter offers multiple output options, including analog and digital signals, making it highly versatile and adaptable to different system requirements.
Product Features of water level transmitter:
1.HART communication protocol output, with display capability
2.High accuracy and excellent stability
3.Explosion-proof rating : ExiaIICT6
4.High protection level, IP68
5.PE, PTFT, PU cables available
Applications of water level transmitter:
1.Compatible with 316LSS,noncorrosive liquids
2.Monitoring water levels in various applications such as sewage, industrial and municipal water, water tanks, wells, rivers, seawater, lakes, etc
3.Diesel, fuel, and other oil tank level monitoring

Ordering tips:
1. Please ensure that the measured medium is compatible with the
product components in contact with it during selection.
2. The density of the measured medium should be specified.
3. For strong electromagnetic or radio frequency interference,
please provide details to our company and indicate it in the order.
4. To ensure the reliable operation of the product, it is
recommended that users install lightning protection devices on-site
and ensure the product and power supply are reliably grounded.
