Product Description
JC621F-12 Liquid Level Transmitter Overview:JC621F-12 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.
JC621F-12 Liquid Level Transmitter Features:* With high sensitivity, fast response and high accuracy of measurement, the high-quality sensor can accurately reflect subtle changes in dynamic or static liquid level.
* Provided with lightning system and intrinsically safe explosion-proof capacity, it is applicable to all kinds of hazardous sites.
* 12V battery can be used to supply power under special conditions, so as to solve the problem of field power supply.
* Easy installation, convenient operation and strong interchangeability
* Fine and unique zero point, temperature drift and non-linear compensation ensure good accuracy and long-term stability of the instrument within the scope of working conditions.

Tips for Type Selection* The medium to be measured shall be compatible with the material contacting with the product. Meanwhile, the density of the medium to be measured during measurement shall be indicated (except for water).
* For battery supply feed, please indicate it in the order.
* As an additional function code for type selection, the code "E" for intrinsically safe explosion-proof type Ex ia II CT5 denotes that power source must be supplied via safety barrier.
* The length of cables shall be L = X m + 1m. Please indicate any extension (if needed) when placing an order. There are two kinds of cable materials. By virtue of its more flexibility and good wear resistance, polyurethane material can be selectively used. Where no special requirement is indicated, cables to be supplied shall be made of PVC material.
* The corresponding relationship of 1m water columns with pressure under standard conditions ( i.e. 4ºC, g = 9.80665 m / s2):1mH2O=0.1kgf/cm2(Kgf /cm2 )=9.8kPa(kPa)
* For other special requirements, please discuss with us and clearly indicate them in the order.
