CYYZ3051SAY Monocrystalline Silicon Double Remote Differential Pressure Transmitter Range 0~4kPa~1MPa 4-20mA HARTprotocol
CYYZ3051SAY monocrystalline silicon dual remote differential pressure transmitter uses monocrystalline silicon resonant sensor technology. The double-flange capillary structure realizes mechanical isolation and thermal isolation, which can cope with complex corrosive media, high temperature media and other sites. It is suitable for measuring the level, volume, density and differential pressure of liquids, gases or vapors. It has a variety of explosion-proof functions, intrinsically safe type, dust intrinsically safe type, flameproof type, and flameproof dust type.
