3308-208-02149 is a digital type pressure control switch from Danfoss. This switch is designed to protect industrial fluids and gas pressure systems from overpressuring or underpressuring. It can be incorporated into a variety of applications, including pumps, blowers, and compressors, to ensure safe and efficient operation. In this article, we will discuss the application field and working principle of 3308-208-02149.

Applications

3308-208-02149 can be used in a variety of industrial applications, including pumps, blowers, and compressors. It is designed to control the pressure of a system, and it can be used to ensure that the system is operating within a safe range of pressures. For example, a pump may require a specific pressure range to maximize efficiency and minimize wear on the mechanical components. By incorporating the 3308-208-02149 into the system, the pump can be monitored and the pressure can be adjusted to maintain the desired pressure range.

Alternatively, 3308-208-02149 can be used in applications where overpressuring or underpressuring must be avoided. For example, a gas system may require specific pressures to prevent damage to components or a hazardous safety risk. In this case, the 3308-208-02149 can be installed to monitor the pressure and adjust it accordingly, avoiding any dangerous overpressuring or underpressuring of the system.

Working Principle

The working principle of the 3308-208-02149 is relatively simple. It consists of a pressure sensing element, an internal switch, and a pilot chamber. The pressure sensing element responds to the pressure within the system, and the internal switch responds to the pressure reading of the sensing element. When the sensed pressure exceeds or falls below a certain predetermined threshold, the internal switch will activate, adjusting the system pressure as necessary.

The pilot chamber is used to sense changes in pressure and control the flow of air or gas within the system. As pressure increases or decreases within the system, the pressure within the pilot chamber will also increase or decrease, causing a corresponding change in the flow of air or gas.

The 3308-208-02149 is designed to be easy to install and maintain. It can be incorporated into existing fluid or gas systems without the need to make any significant modifications. Additionally, the adjustable settings of the 3308-208-02149 can be conveniently changed to accommodate changing system pressures.

Conclusion

The 3308-208-02149 provides reliable pressure control for industrial fluid or gas systems. It can be used to protect the system from overpressuring or underpressuring, and it can be easily incorporated into existing systems. The 3308-208-02149 includes a pressure sensing element, an internal switch, and a pilot chamber, all of which work together to automatically adjust and maintain the system pressure.
