Chinese supplier free shipping fee  4-20ma water tank level sensor

 Model:  WP311A


1. WP311A Immersion type water level transmitters (also called static level transmitter) adopt advanced imported sensitive component with anti-corrosive diaphragm, the sensor chip was put inside a stainless steel (or Teflon) shell. 

2. A special vented cable was used, and made the back pressure chamber of diaphragm connect well with atmosphere, and level measurement was not varied according to the change of external atmospheric pressure.  

3.  The function of iron cap at the top is protecting transmitter, and the cap can make the measured liquid touch the diaphragm smoothly. 

4. With exact measurement, long term stability, excellent seal and corrosion proof, this transmitter meets the standard of ship, and it can be thrown directly in water, oil and other liquids for a long time. 

u  Special internal construct technology completely solved the problem of condensation and dewfall 

u  Special designed electronic technology basically solve the problem of lightning strike
