HM22 High - accuracy Pressure Transducer
Description
HM22 High - accuracy pressure transducer is a new pressure transducer jointly developed, researched, and produced by us and German HELM Company. HM22 High - accuracy pressure transducer is designed with Germany made high–accuracy force–sensitive chip as a central sensing and measuring element, using such new high technology as temperature automatic compensation and normalized circuit commissioning etc. to greatly enhance overall accuracy of the product. This product is designed with advanced technology, superior performance, reliable quality, and small dimension, which may widely be used for such scientific research and production fields as airspace and aerospace, petroleum, chemical, metallurgical and electric power, building material, hydrographic and geographic, medical, protection of environment etc. It may realize high–accuracy measurement of fluid pressure and liquid level.
Features of Product
☆ Designed with Germany made high–accuracy force–sensitive chip as a central sensing and measuring element, with a accuracy up to 0.1% FS
☆ Designed with sensor temperature automatic compensation and normalized circuit commissioning to enhance temperature stability indicator up to 0.1% FS / ℃.
☆ May measure corrosive and easily crystalline medium under special requirements
☆ Designed with fully enclosed structure, all structural members made of stainless steel, which may be used in the open air for a long time.
☆ May be used for the site with online temperature measuring for a long time and without calibration.
☆ May be used for hazardous site, with intrinsically safe type Ex ia II CT5
☆ Structural diversification, design may be customized at the customer’s special requirements.
