| ¢ñ. Brief Introduction
In petrochemical enterprise, during the process of feeding, polyolefin powder may produce a lot of static that make powder caking and easy to induce fire. For a long period powder static eliminator was recommended to use, but as practical technology of measure of line of powder static, the above suggestion hasn¡¯t been implemented all alone. First reason is offsetting static distribution, the traditional measure technologies as voltage and current can not measure the danger degree of powder charge; the second reason is bad measure environment, the reliability of measuring component are often affected by dust and damp.

DQJ-2 powder static monitoring instrument are designed by Chinese famous static expert and developed and manufactured by Industrial Powder Flameproof Institute of Jiangsu Dongqiang Co., Ltd. With distorted Farad trunk, it has fulfilled measure on line of powder unity essence that represents essence of powder electric charge and can be used to evaluate and monitor the danger of powder static. The product shall be used mating with DQJ-1 powder static eliminator with ion wind so as to raise reliability of eliminator and access the best electricity elimination efficiency. With advanced technology, the product has advantage of using conveniently and fill up the blank of measure on line of powder static in the country. Main technology index is as follow:
1. Measuring scope: 0~¡À19.99¦ÌC/kg
2. Identify rate: 0.01¦ÌC/kg
3. Measuring error: <10%
4. Flameproof symbol: Exib ¢òT4
¢ò. Structure and Specification
The product is composed of sensor and quadratic instrument; profile is as chart1 and chart 2. The sensor is installed in the pipeline between DQJ-1 powder static eliminator with ion wind and feeding entrance of hunker.
Specification: ¦µ100mm, ¦µ150mm, ¦µ200mm feeding pipeline series
