Digital pressure controller uses high-reliability sensor to measure pressure. After back-end circuit processing, the signal is displayed on the display and automatically controls the relay output when the pressure changes.
Features
- It adopts high-reliability sensor to ensure accurate pressure monitoring.
- Automatic relay control and adjustable parameters according to pressure changes provide flexible settings and operations.
- Engineering plastic housing and anti-vibration design ensure the stability and long life of the equipment.
- High-contrast LCD display and simple operation interface facilitate users to monitor and adjust in real time.

Load Working Mode

Hi-P: OFF pressure value Lo-P: ON pressure value
The pressure switch will monitor the pressure in the container in real time, and start and stop (ON/OFF) the load according to the set value to control the pressure. You can also achieve more parameter changes, lock protection, etc. through menu settings.
Applications

Tips: How to choose digital air compressor pressure switch
- Pressure range: Make sure the selected switch is suitable for the working pressure range of the equipment.
- Fluid type: Select a suitable pressure switch according to the fluid used by the equipment (such as air or gas).
- Protection level: Select a pressure switch with sufficient waterproof and dustproof rating to ensure stable operation in harsh environments.
- Display and operation: Select a pressure switch with clear display and easy operation for real-time monitoring and adjustment.
- Connection method and installation: Make sure the connection method of the pressure switch matches the equipment for easy installation.
