Product Description


BH93420 III Water level Transmitter

Introduction of water level transmitter: 

BH93420-III Piezoresistive water level transmitter adopts the piezoresistive sensor principle to determine the liquid level height by measuring the pressure effect of the medium on the sensor. When the liquid height increases, the pressure of the medium on the sensor increases, resulting in a change in the resistance value of the sensor. The piezoresistive liquid level transmitter converts it into an electrical signal output related to the liquid level height by measuring the change in the resistance value of the sensor. The transmitter can accurately calculate the liquid level height according to the linear relationship between pressure and resistance.
