BH93420 III Water level Transmitter
Introduction of water level sensor:
BH93420-III water level transmitter is equipped with a highly precise Piezoresistive diffused silicon pressure sensor as its signal measuring element.It measures the static pressure, which is directly related to the water level, and converts it into a standard signal output using amplification circuitry. By establishing a linear relationship between the output signal and the liquid level,it ensures precise and accurate measurement of the water level.
Product Features:
1. It uses a high-precision diffused silicon sensor to accurately measure the liquid level or pressure.
2. It has stable performance and a long lifespan, making it suitable for harsh environmental conditions.
3. It has a high-precision measurement range and adjustable measurement range to meet different application requirements.
4. The device utilizes advanced digital signal processing technology to achieve high-precision measurement output.
5. The diffused silicon immersion-type liquid level transmitter has excellent anti-interference capability, allowing it to function properly in complex industrial environments.
6.The liquid level transmitter supports a variety of communication interfaces, allowing data interaction with other devices
Applications:
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
