Highlight: | Flat Membrane Pressure Transmitter,Pressure Transmitter Sanitary |
---|
The CYYZ51DEY flat film type pressure transmitter is designed to measure adhesion, crystallization, mixed contamination and other media. The flat membrane design is adopted to effectively prevent the blockage of the impulse hole. The process connection adopts the sealing method of the lower end of the thread, so that the measuring medium is effectively isolated from the connection thread, and the adhesion and mixed contamination of the threaded connection are avoided. It has two explosion-proof functions of intrinsically safe type and dust intrinsically safe type, and can also choose HART protocol communication, which is cost-effective.
