4-20MA Water Level Transmitter Liquid Level Transducer Sensor 1-10M Cable
Structure principle：
Hydrostatic level transmitter liquid level sensor is determined by measuring the static pressure generated by the level. Hydrostatic pressure using the formula P = Po +pgh, where: Po is the atmospheric pressure above the liquid level,p is the measured liquid density, H is the height of the liquid, g is the gravitational acceleration (constant). When Po remains constant, the pressure depends on the density and level two variables. When the liquid density is constant, the level will vary linearly with pressure. The pressure in the pressure-sensitive surface of the transmitter diffusion silicon pressure sensors, piezoresistive effect by the sensor, the column pressure into a voltage signal. This signal is amplified directly converted into 4 ~ 20mA.
If an upper level atmospheric pressure changes, the pressure sensor will be the same as the level changes affect. WRT-136 uses a macaroni ventilation cable design methodology, the external atmospheric pressure introduced into the other side of the pressure sensitive sensor surface. By the atmospheric pressure thus eliminating
