CYYZ3051ZAY monocrystalline silicon direct-mount pressure transmitters use monocrystalline silicon resonant sensor technology. Suitable for measuring the 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.
