ESL040M Separated Liquid Level Transmitters
ESL040M line is liquid level transmitter with compact and separate design. Featuring high reliability, stability and accuracy, the product is widely used for the measurement of liquid level in small-diameter pipe or liquid storage tank, such as water, oil and light corrosive liquids. This product line adopts 1Cr18Ni9Ti stainless steel construction, active sensing element of international brands, and the specially designed V/I converting circuit. It is easy to perform zero/span trim as well as external program-controlled zero/span adjustments. Based on the locations, different high-strength breathable cables featuring wear-proof, acid/alkali resistance and oil resistance can be configured. Non-polarized two-wire output and DC-AC three-wire output available.

Technology
The probe measures liquid levels, basing on a simple relationship between the height of the liquid column and the resulting hydrostatic pressure. The pressure measurement is carried out on the level of separating diaphragm of the immersed probe and is related to atmospheric pressure through a capillary in the cable.
The active sensing element is a piezoresistant silicon sensor separated from the medium by an isolating diaphragm. The electronic amplifier, which words in combination with the sensor, and is meat to standardize the signal, is additionally equipped with an overvoltage protection circuit, which protects the probe from damage caused by induced interference from atmospheric discharges or from associated heavy current engineering appliance.
