NY70 Series Intelligent Pressure Switch

The NY70 Series Intelligent Pressure Switch is a multifunctional digital pressure controller that integrates pressure measurement, real-time display, and programmable switching control into a single compact device.

Designed for industrial automation, hydraulic equipment, water treatment, fire protection, and process control, the NY70 Series delivers reliable pressure monitoring with fast response, flexible configuration, and long-term stability.

What Is an Intelligent Pressure Switch?

An intelligent pressure switch continuously measures system pressure and automatically activates or deactivates equipment when preset pressure thresholds are reached.

Unlike conventional mechanical pressure switches, the NY70 Series uses a fully electronic design with a high-performance pressure sensor and digital signal processing to achieve greater accuracy, stability, and user flexibility.

Typical control applications include:

• Pump start/stop control

• Compressor pressure control

• Hydraulic system protection

• Pressure alarm systems

• Automatic process control

Working Principle

The NY70 Series combines an oil-filled piezoresistive pressure sensor, high-speed A/D conversion, and an embedded microprocessor.

The pressure signal is converted into digital data, displayed in real time, and compared with user-defined switching values.

When the measured pressure reaches the configured setpoint, the controller automatically outputs the corresponding switching signal to control pumps, valves, compressors, or other equipment.

Key Features

All-in-One Digital Pressure Control

The NY70 integrates multiple functions into one device:

• Pressure Measurement

• Digital Pressure Display

• Programmable Switching Output

• Pressure Controller

• Pressure Alarm

This simplifies installation while reducing wiring and maintenance costs.

High Measurement Accuracy

Available accuracy classes:

• ±0.2% Full Scale

• ±0.5% Full Scale

High-speed digital processing ensures stable and repeatable pressure control.

Intelligent Digital Configuration

Users can configure operating parameters directly from the front panel without additional software.

Supported functions include:

• Start Pressure Setting

• Stop Pressure Setting

• Switching Point Adjustment

• Parameter Memory

• Zero Calibration

• Pressure Unit Configuration (optional)

All settings are automatically retained during power interruptions.

Automatic Zero Calibration

The built-in Auto Zero function compensates for atmospheric pressure drift.

Simply press and hold the reset button to recalibrate the zero point, improving long-term measurement accuracy.

Fast Response

• Response Time: <30 ms

• Suitable for rapidly changing pressure systems

• Reliable switching performance for dynamic industrial processes

Technical Specifications

How to Configure the NY70 Pressure Switch

The NY70 Series is designed for simple on-site setup.

Step 1 – Set the Start Pressure

Press the SET button and adjust the desired start pressure.

Example:

Start Pressure = 0.30 MPa

Step 2 – Set the Stop Pressure

Configure the stop pressure value.

Example:

Stop Pressure = 0.60 MPa

Step 3 – Save Parameters

Confirm the settings.

The controller automatically stores all parameters, even if power is removed.

Step 4 – Zero Calibration

If necessary, press and hold the Reset button to perform automatic zero calibration and eliminate atmospheric pressure offset.
