ESL040T Temperature Liquid Level Transmitters

ESL040T line is the transmitter applicable for measuring the temperature and pressure at the same time. Featuring high reliability, stability and accuracy, the product is widely used for the measurements of gas and liquid, such as water, oil and light corrosive liquid and gas. This product line adopts 1Cr18Ni9Ti stainless steel construction, diffused silicon-based sensor of international brands, and the specially designed V/I converting circuit. It is easy to perform zero/span trim. Based on the locations, different high-strength breathable cables featuring wear-proof, acid/alkali resistance and oil resistance can be configured.

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.
