Analysis of the Advantages of Double-Contact Vacuum Pressure Switches

The double-contact vacuum pressure switch has the following advantages in application scenarios such as vacuum packaging machines:

The dual contacts are independently adjustable, providing flexible control

The double-contact vacuum pressure switch is equipped with two sets of microswitches respectively inside the pressure housing, and the set points of the two sets of switches are independently adjustable, capable of respectively output two sets of switch quantity signals. This design enables users to flexibly set different pressure thresholds according to actual needs, achieving more precise control. For instance, in a vacuum packaging machine, the pressure values for starting and stopping the vacuum pump can be set separately to ensure the stability and efficiency of the packaging process.

Improve the stability and reliability of the system

The dual-contact design is equivalent to two pressure switches being connected in series or parallel, and in actual control, it has better stability than single-contact switches. When one of the contacts fails, the other contact can still continue to work, thereby enhancing the reliability of the entire system. This is particularly important for vacuum packaging machines that need to operate continuously for long periods of time, as it can effectively reduce production interruptions caused by equipment malfunctions.

Adapt to various working conditions and media

The double-contact vacuum pressure switch has a wide range of pressure connection interface options and medium temperature adaptability (ordinary 0-80℃, high-temperature 0-300℃), and can adapt to different working environments and medium conditions. In vacuum packaging machines, this can ensure that the switch can work stably under various packaging materials and process requirements.

Convenient for integration and expansion

Double-contact vacuum pressure switches typically feature multiple pressure connection interfaces and relay contact capacity options, facilitating integration with other control systems of vacuum packaging machines. Meanwhile, its adjustable pressure threshold setting function also enables the switch to adapt to possible future process changes or equipment upgrade requirements.

Reduce maintenance costs

Due to the dual-contact design enhancing the stability and reliability of the system, it can reduce downtime and maintenance costs caused by equipment failures. In addition, the seismic performance of the switch (max20m/s) and repeatability (≤4MPa±1.0%FS; (>4MPa±1.5%FS) also ensures its long-term stable operation in harsh working environments.
