China low cost 4-20mA water level sensor

Summary                                                                          

EB2088T submersible liquid level transmitter with high performance of the pressure sensor, special ventilation cable, make sure the back pressure cavity and the atmosphere connecter well, liquid level measurement from the influence of the outside atmospheric pressure changes, make sure measurement accuracy and performance stablely. Has excellent sealing and anti-corrosion performance. Comply with the ship standards, can be directly put into the water, oil and other liquids in long-term use. Multiple structural forms, and multiple types transmitter, make it wide adaptability. (When the measured medium is not stable, the probe of the cable type liquid level transmitter is easy to produce displacement, which affects the measurement accuracy. At this time the probe should be fixed. If the probe could not be fixed in the site, please selecting ballast to increase the probe weight and play a role in the stability of the probe. If you need the counterweight, please specify when ordering).

Stability: 0.2%F.S. /year

Working principle:

A point of the liquid static pressure and the point to the surface is proportional to the distance, namely P= ρgh. 

P : measured point pressure; 

ρ : medium density, 

g: the acceleration of gravity the using place,

h: measured point to the surface.

For have been identified in the measured medium and the place, P G is constant, so the measured changes in the position of the point to the surface is only associated with the measured pressure.
