The GYP-A1 series intelligent pressure controller is an intelligent digital display pressure measurement and control product that integrates pressure measurement, display, output, and control into one unit. This product features an all-electronic structure, with a front-end isolated oil-filled piezoresistive pressure sensor, high-precision A/D conversion, and processing by a microprocessor for on-site display. It outputs one analog signal and two switch signals. This intelligent digital pressure controller is flexible to use, simple to operate, and safe and reliable. It is widely used in industries such as hydropower, petroleum, chemical, machinery, and hydraulics for on-site measurement, display, and control of fluid medium pressure.
