HTsensor 316L Stainless Steel IP68 Liquid Level Transmitter with 4-20mA Output and LED Display
HTsensor LCD Pressure Sensor - Stainless Steel Water Leak Sensor Probe Fuel Meter Transmitter
Model BH93420-III liquid level measurement sensor with 4-20mA LED display for precise industrial monitoring 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 advanced amplification circuitry. The linear relationship between output signal and liquid level ensures precise and accurate water level measurement.
