NY35 Series Intelligent Digital Pressure Switch

The NY35 Series Intelligent Digital Pressure Switch is a multifunctional pressure monitoring device that combines pressure measurement, digital display, programmable switching, and analog signal transmission into one compact instrument.

Designed for industrial automation, hydraulic systems, pneumatic equipment, and process control, the NY35 provides accurate pressure monitoring, flexible configuration, and reliable long-term operation.

Its integrated LED display and intelligent programming functions make installation and operation simple while improving system efficiency.

What Is a Digital Pressure Switch?

A digital pressure switch continuously monitors system pressure and automatically controls equipment when preset pressure thresholds are reached.

Compared with conventional mechanical pressure switches, the NY35 offers:

• Higher measurement accuracy

• Digital pressure display

• Programmable switching points

• Analog signal output

• Flexible parameter configuration

• Better long-term stability

It is ideal for modern industrial automation systems requiring both local monitoring and remote signal transmission.

Working Principle

The NY35 Series uses either a ceramic pressure sensor or a thin-film pressure sensor to accurately measure pressure.

The pressure signal is processed by an internal microprocessor and displayed on the integrated LED screen in real time.

Users can configure switch points, output signals, and display parameters directly from the on-device menu.

When the measured pressure reaches the programmed value, the switch output activates while the analog output simultaneously transmits the current pressure value to PLCs, HMIs, SCADA, or other control systems.
