Product Overview
The JEF514 Smart Pressure Controller is an intelligent digital pressure measurement and control product that integrates pressure measurement, display, output, and control. This product features a full electronic structure, with a front-end pressure sensor that employs an oil-filled resistive pressure sensor with an isolation membrane. It is equipped with high-precision A/D conversion, processed by a microprocessor, and provides on-site display. It also outputs one analog signal and four switch signals. The intelligent digital pressure controller is versatile, easy to operate, simple to debug, and reliable. It is widely used in industries such as water and electricity, tap water, oil, chemicals, machinery, and hydraulics for on-site measurement, display, and control of fluid medium pressure.
