Product Description
Product Overview JC622-25 Pressure Transmitter is a new pressure transducer jointly developed, researched and produced by our 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.
