Product Summary

The NOIKE-AH Intelligent Pressure Switch NY70 Series  is a compact digital instrument that combines pressure measurement, display, switching output, and control in a single device. Designed with an isolated oil-filled piezoresistive pressure sensor and high-speed microprocessor, it delivers accurate pressure monitoring and fast switching response for industrial automation systems.

Featuring a programmable front-panel interface, power-loss memory, and automatic zero calibration, the intelligent pressure switch is ideal for pump control, pressure protection, hydraulic systems, fire protection, water treatment, and process automation.

Working Principle

The Intelligent Pressure Switch NY70 uses a high-precision piezoresistive pressure sensor to detect system pressure.

The measured pressure signal is converted through a high-resolution A/D converter and processed by an internal microprocessor. The real-time pressure value is displayed on the digital screen while continuously comparing the measured value with user-defined set points.

When the pressure reaches the preset start or stop values, the controller automatically activates the corresponding switching output to control pumps, compressors, valves, or alarm systems.

The built-in memory retains all parameter settings after power interruption, and the automatic zero function compensates for atmospheric pressure variations to improve measurement accuracy.
