Liquid Level Transmitter with Accuracy and LED Display Water Pressure Transmitter

Liquid Level Transmitter with Accuracy and LED Display Water Pressure Transmitter

BH93420-III Water Level Transmitter with Display

The BH93420-III water level transmitter utilizes a highly precise Piezoresistive diffused silicon pressure sensor to measure static pressure, which directly correlates to water level. This pressure is converted into standard signal output through amplification circuitry, establishing a linear relationship between output signal and liquid level for precise and accurate measurement.
