DEVI KPI35 Pressure Switch -0.2 to 8 bar, G 1/4 Connection, IP55

The DEVI KPI35 pressure switch is a high-precision control device engineered to monitor and regulate pressure levels in liquid and gaseous media systems. Designed for durability and consistent performance, this unit provides reliable switching operations within an adjustable range of -0.2 to 8 bar. Its robust construction and IP55-rated enclosure ensure that the internal components remain protected against dust ingress and low-pressure water jets, making it an ideal solution for demanding industrial environments and complex plumbing installations.

Advantages

This pressure switch stands out due to its versatile pressure adjustment range and adjustable hysteresis, which allows for fine-tuning based on specific system requirements. The unit is built to withstand high operational pressures up to 18 bar, ensuring safety and longevity even in fluctuating conditions. Its compact design and standard G 1/4 connection facilitate straightforward integration into existing piping networks, while the high-quality materials used in its manufacturing guarantee long-term operational stability and minimal maintenance needs.

Suitable for

• Industrial pressure control systems
• Heating and cooling installations
• Water supply and pumping stations
• Compressed air systems
• Fluid management in manufacturing processes

This device may not be suitable for applications involving highly corrosive or aggressive media that could damage the internal sensing elements. It is also not intended for use in explosive atmospheres or environments where the pressure exceeds the maximum rated limit of 18 bar, as this could lead to mechanical failure or safety hazards.

Key specifications

• Pressure range: -0.2 to 8 bar
• Hysteresis: 0.4 to 1.5 bar
• Maximum operating pressure: 18 bar
• Connection type: G 1/4
• Ingress protection rating: IP55
• Weight: 451 g

Installation should be performed by a qualified technician to ensure proper calibration and safety. The device is mounted directly onto the pressure line using the G 1/4 connection. Once installed, the pressure setpoint and hysteresis can be adjusted using the integrated controls to match the operational requirements of the specific system. Ensure all electrical connections are secured according to local regulations before activating the system.

What to consider before purchase

• Verify that the system pressure does not exceed the 18 bar maximum limit.
• Ensure the media being measured is compatible with the device materials.
• Check that the G 1/4 connection is compatible with your existing piping.
• Confirm that the IP55 rating is sufficient for your installation environment.

For optimal performance, regularly inspect the pressure switch for signs of wear or debris accumulation. Ensure that the electrical contacts remain clean and that the unit is not subjected to excessive vibration, which could affect the accuracy of the pressure readings over time.
