CYYZ73CY Single Flange Type Pressure Transmitter Range -100kPa～0～4MPa Accuracy 0.5%FS Exhaust Gas Chemical Oil And Gas
The CYYZ73CY single flange pressure transmitter is designed for corrosive, viscous media. The diaphragm adopts flush membrane process (diaphragm material is 316L, tantalum, Harbin C optional). And there are a variety of explosion-proof function options, intrinsically safe type, dust intrinsically safe type, flameproof type, flameproof dust type, and can also choose HART protocol communication, cost-effective.
