BH93420 III Water level TransmitterIntroduction 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.Product Features:- Split-type design, facilitating on-site wiring and calibration
- LED display
- Explosion-proof rating : ExiaIICT6
- High protection : IP68
- Cable : PE,PU.PTFE
Applications:
1. widely used in the level monitoring and control of storage
tanks, tank cabinets, pipelines and other containers.
2. It can be used in liquid storage and transportation systems in
petroleum, chemical, pharmaceutical and other industries to ensure
that the liquid level is within a safe range.
3. Piezoresistance liquid level transmitter can be used in water
treatment equipment to monitor the liquid level of water tanks,
pools, etc., to achieve automatic control.
4. It is suitable for canning, filling and other processes in the
food processing industry to ensure that the liquid level of the
product meets the standard.
5. Piezoresistive level transmitter can be used for environmental
monitoring, such as the level monitoring of rivers, lakes and other
water bodies.
6. It can be used in ships and offshore engineering to monitor the
liquid level of ship fuel tanks, cabins, etc.
