HM26 Ceramic Capacitor Pressure Transducer
Description
HM26 ceramic capacitor pressure transducer adopts internationally advanced ceramic capacitor sensor, supported with high–accuracy electronic elements, and assembling with strict process. It adopts dry pressure measuring technology without intermediate liquid, thick membrane electronic technology, SMT (surface mount technology) and PFM signal transferring technology to fully play a role of technical advantages for ceramic capacitor sensor so as to make that the pressure transducer features excellent technical performance. It features strong anti–overloading and anti–impact capacity, high stability, and very high accuracy of measurement. This series of product may widely be used for such industrial fields as petroleum, chemical, metallurgical, electric power, pharmaceutical, and food etc.
Features of Product
☆ Strong anti – overloading and anti – impact capacity, with over pressure up to several dozens to hundred times of scale
☆ Adoption of imported ceramic capacitor sensor, with strong signal output, high comprehensive accuracy, and good stability
☆Small temperature drifting due to without intermediate liquid for measuring element
☆ Wide range of pressure, from micro pressure 0.5kPa to high pressure 100MPa, with optional combined pressure with positive and negative pressure
☆ Pure ceramic substrate will not result process pollution. It applies to food and medical industrial.
☆ Strong disturbance immunity, water – proof, dust – proof, vibration – proof, explosion – proof, and corrosion – proof.
☆ Intrinsically safe explosion – proof, with explosion – proof Class Ex ia II CT5
