220V Digital Pressure Controller Switch | 0-10 Bar, 1/2" Port
220V Digital Pressure Controller Switch | 0-10 Bar, 1/2" Port
220V Digital Automatic Pressure Controller Switch for Water, Oil & Air Compressors
Take full automated control of your pump system with this intelligent digital pressure controller switch. Designed for water pumps, oil systems, and air compressors, this CE-certified unit features a built-in pressure transmitter for rock-solid accuracy across a 0–10 Bar working range. Its microcomputer process chip handles all the logic — automatically switching the pump on when pressure drops and off when it's restored — so you never have to monitor it manually.
Key Features
- Built-in Pressure Transmitter: Delivers stable, accurate pressure readings for consistent automated control.
- Automatic On/Off Operation: Switches the pump on when water is detected and off during water-shortage conditions — protecting your pump from dry running.
- Microcomputer Control Chip: Smart, safe, and reliable intelligent processing for hands-free operation.
- One-Click Setup: Easily configure your upper (H) and lower (L) pressure limits with a single button press.
- IP65 Waterproof Rating: Splash- and dust-resistant housing for use in demanding environments.
- Wide Compatibility: Works with all standard pumps up to 1.5 kW; 1/2" interface fits most standard plumbing connections.
- CE Certified: Meets European safety standards for low-voltage electrical equipment.

Installation Notes
- If your pump does not include a check valve, install one upstream of the pressure switch to prevent rapid on/off cycling.
- If the pump cycles on and off while the tap is open, adjust the H (high) pressure limit to a higher value.
- If the pump runs continuously without stopping, lower the H valve setting. If the pump fails to start, raise the L (low) valve setting.
Package Includes
- 1 × Digital Pressure Controller Switch

Frequently Asked Questions
Q: What types of pumps is this digital pressure controller switch compatible with?
A: This pressure controller switch is compatible with most standard water pumps, oil pumps, and air compressors up to 1.5 kW with a 220V AC supply. The 1/2" threaded interface fits the majority of standard plumbing and pump outlets, making it a versatile choice for domestic and light industrial use.
Q: How do I set the on and off pressure limits?
A: The switch features a simple one-click setup system. Use the H button to set the upper (cut-off) pressure limit and the L button to set the lower (cut-in) limit. The onboard digital display shows the current pressure in real time, making it easy to dial in your preferred settings.
Q: Is this pressure switch safe for outdoor or wet environments?
A: Yes. The unit carries an IP65 waterproof rating, meaning it is fully protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for installation in utility rooms, pump houses, or outdoor enclosures where moisture may be present.
Q: Why does my pump keep cycling on and off rapidly?
A: Rapid cycling is usually caused by a missing or faulty check valve. If your pump does not have a built-in check valve, install one upstream of the pressure switch. You can also try increasing the H (high) pressure limit slightly to widen the gap between the cut-in and cut-off points, which reduces cycling frequency.
