The SOR 56NN-K316-M2-C1A pressure vacuum switch is a pneumatic device designed for use in various industrial applications where monitoring and controlling vacuum levels is essential. This switch is specifically adjusted for a vacuum range of 30-0-160 hg (hectopascal).
The SOR 56NN-K316-M2-C1A is constructed of high-quality materials, ensuring durability and reliability in harsh operating environments. The switch body is made of brass, known for its excellent corrosion resistance, while the diaphragm is made of an elastomer material that is resistant to oil and fuel.
The switch operates on a simple principle: when the vacuum level drops below the set point, the diaphragm moves inward, closing the contact and initiating an alarm or other action. Conversely, when the vacuum level rises above the set point, the diaphragm moves outward, opening the contact and stopping the alarm or other action.
The SOR 56NN-K316-M2-C1A is a normally open (NO) switch, meaning that it is not conducting electricity when the vacuum level is within the set point range. When the vacuum level drops below the set point, the switch closes and allows the flow of electricity.
This pressure vacuum switch is designed to meet the needs of industrial applications that require precise control over vacuum levels. Its adjustable vacuum range of 30-0-160 hg makes it a versatile solution for various processes and systems. With its durable construction, reliable operation, and easy installation, the SOR 56NN-K316-M2-C1A pressure vacuum switch is an essential tool for any industrial facility.
