Product Description
Product overview
HM27A absolute pressure transducer adopts such advanced foreign new high technologies as absolute pressure chips, temperature automatic compensation, and normalized circuit debugging etc., to expand the absolute pressure range to 5KPa at the minimum, and to greatly enhance the overall accuracy of the product. Characterized by advanced technology, superior performance, reliable quality and small volume, this product has quite obvious advantages in high cost performance by comparison with domestic similar absolute pressure products.
By use of a HELM mono-crystalline silicon thick-film sensor, HM27G negative pressure transducer is equipped with a high-accuracy signal processing circuit, with stable and reliable performance, which has solved such disadvantages of domestic diffused silicon-type negative pressure vacuum products as unstable signal and short service life. Normal ranges include 0 ~ 100KPa and 0 ~ 50KPa, etc..
HM27CA capacitor thin-membrane absolute pressure transducer is a vacuum pressure gauge made in China through the introduction of foreign capacitor thin-film gauge technology and internationally advanced calibration equipment. This product works by the capacitance changing principle. Its minimum range may be up to 0.02MPa ~ 200MPa absolute pressure, and its detection won't be influenced by the type and component of the medium to be detected. Its output of standard electric signals can be remotely transmitted, to facilitate intelligent control of microprocessors. Therefore, it is ideal for the measurement of low vacuum pressure.
