CYYZ51DAY flat-film pressure transmitters are designed to measure viscous or colloidal media. The design of the impulse hole is canceled, which effectively prevents the blockage of the impulse hole, and 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.
