ESL046 Marine Titanium Alloy Liquid Level Transmitter
ESL046 line is liquid level transmitter specially designed for the seawater-related measurements. The product line is highly reliable and stable, and enables digital compensation within full temperature range. The ESL046 line adopts titanium alloy construction to the oil fill system and housing, the latest digital compensation technology to ensure no losing of accuracy within the full temperature range, and enables zero/span trim through computer interface and 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.

Seawater measurement | Ship draft measurement | Water level of seaport wharf | Height measurement of bridge over the sea | Corrosive mediums
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.
