Product Description


The YD42 LED display pressure controller is a comprehensive solution for pressure measurement, display, intelligent digital pressure sensing, and control output. This fully electronic device incorporates a front-end hydraulic resistance-type pressure sensor with baffle filling. The output signal undergoes processing by a high-precision, low-drift amplifier before being fed into a high-accuracy A/D converter. The resulting digital signals are then processed by a microprocessor, enabling precise control of switches and effective monitoring of the pressure control system.

The Digital Air Pressure Switch offers exceptional flexibility, straightforward operation, effortless debugging, and robust reliability. It finds widespread application in various industries, including hydropower, water supply, petroleum, chemicals, machinery, hydraulics, and more. Whether it's for fluid medium pressure measurement, display, or control, the YD42 LED display pressure controller is an ideal choice.
