product description ZRN205 series Explosion-proof Pressure Transmitter It is designed for high explosive hazard workplace design, and absolute pressure in a liquid or gaseous medium, gauge pressure, differential pressure to provide a stable and accurate measurement between -100KPa to 200MPa. It uses the welding process will be ready German HELM polysilicon thin film biography sense element and the housing insulation displacement connector as a whole, may be required to quickly customized to suit the individual needs of different users, and maintains all the original features of HELM pressure sensor chip. Built-amplifying circuit, structural forms, can be with M20 * 1.5 or G1 / 2 internal thread hose connector explosion.
ZRN205 series Explosion-proof Pressure Transmitter Good performance, small size, flexible design, compared with the traditional explosion-proof transmitter with high performance and low cost, and long service life, widely used in oil fields, mines, chemical, electric power, boilers, natural gas and other fields. • The Ann and explosion-proof certification: Ex iaⅡCT5, Ex dⅡCT6
• Measuring range: -100KPa ~ 0 ~ 200Pa ~ 200MPa
