BH93420-III Water Leak Sensor Liquid Level Transmitter
BH93420-III liquid level measurement sensor with 4-20mA LED display for precise liquid level monitoring in various industrial applications.
Product Introduction
The BH93420-III liquid level sensor utilizes a highly precise Piezoresistive diffused silicon pressure sensor as its signal measuring element. It measures static pressure directly related to water level and converts it into standard signal output using amplification circuitry. The linear relationship between output signal and liquid level ensures precise and accurate water level measurement.
