JC621 Liquid Level Transmitter Overview:

The measurement of water or liquid level using hydrostatic equilibrium system is an important application of pressure sensors. The high–sensitivity silicon piezoresistive sensitive element fabricated with micromachining technology is the critical component of the liquid level transmitter, supported with the special cable provided with an air tube as well as special water-tightness technology, which not only ensures the water tightness of immersion transducers, but also makes the reference pressure chamber connect with the ambient atmosphere, so as to attain accurate measurement results and excellent stability. JC621 liquid level transmitter adopts the internationally advanced dry ceramic capacitive sensor or temperature-compensating isolation diaphragm diffused silicon pressure sensor as a sensing element to greatly enhance operating performance of the product. It can be extensively used for the measurement and control of water and liquid levels in petroleum, chemical, power generation plant, urban water supply & drainage and hydrologic exploration fields, etc..

JC621R anti-corrosive liquid level transmitter is specially designed for measuring sea water level and viscous & corrosive liquid level by completely using the latest state-of-the-art technology. The use of titanium alloy large flush-diaphragm sensors, advanced manufacturing and encapsulating techniques, as well as high–accuracy electronic elements has greatly enhanced service life and comprehensive performance of the product. The use of internationally state-of-the-art ceramic capacitive sensors, dry pressure measuring technology with intermediate liquid, thick-film electronic technology, surface mount technology (SMT) and PFM signal transmission technology has given full play to technical advantages of ceramic capacitive sensors, with strong corrosion, overloading and impact resistance capabilities, high stability, and quite high measuring accuracy. This series product can be extensively used in many measurement and control fields of such corrosive and viscous liquid levels as sea water level.

JC621F anti-lightning liquid level transmitter is used to measure the liquid level using the principle that the liquid static pressure is directly proportionate to the liquid height. By use of foreign advanced silicon piezoresistive sensitive elements, supported with patented lightning protection devices, this series of products is specially designed for thunderous areas in Southern China, and is applicable for liquid level measurement of rivers, lakes, reservoirs and head water tanks, particularly of the hydrology and water conservancy of strong thunderous areas in Southern China and high mountain regions in Northern China. It has been successfully applied in many hydrographic industries in China.
