JC622 high-accuracy pressure transmitter is a new pressure transducer jointly developed, researched and produced by our company and a foreign company. This series of products adopts high-accuracy force-sensitive chips imported from Germany as central sensing elements, as well as such new high and new technology as temperature-self-compensation and normalized circuit commissioning etc., thus greatly enhancing their overall accuracy. With advanced technology, excellent performance and reliable quality, this product is of small volume and light weight, and easy to install and use, and can be extensively used in such scientific research and production fields as airspace and aerospace, petroleum, chemical industry, metallurgy, electric power, building material, hydrogeology, medical treatment and  environmental protection etc..  It can realize high-accuracy measurement of fluid pressure and liquid level.


* High-accuracy force-sensitive chips imported from Germany serve as central sensing elements, with up to 0.1% FS accuracy.
* Sensor temperature-self-compensation and normalized circuit debugging are adopted to enhance the temperature stability index to 0.01%/FS/ºC.
* The product can be used to measure corrosive and easily crystallized media according to special requirements.
* With its structural parts made of stainless steel, the product of fully enclosed structure can be used in the open air for a long time.
* It can be used in places where online measurement has been carried out for a long time, but cannot be calibrated.
* It can be used in hazardous areas, with intrinsically safe type Ex ia II CT5.
* With structural diversity, the product can be designed in an individualized manner as per customers’ special requirements.

Tips for Type Selection

1. The medium to be measured shall be compatible with the material contacting with the product.
2. 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
3. For other special requirements, please discuss with us and clearly indicate them in the order.
