3. Product Overview
The Pressure Switch MT-P100PS series is built to deliver precise pressure monitoring and switching capabilities. It integrates seamlessly into process automation systems, ensuring consistent performance even under fluctuating pressure conditions.
Its design utilizes a welded stainless-steel sensing element, providing exceptional corrosion resistance and mechanical strength. The hermetically sealed switching mechanism helps maintain stable electrical operation and prevents contamination or moisture ingress.
Whether used to activate alarms, control flow systems, start pumps, or stop compressors, the Pressure Switch MT-P100PS ensures accurate response and dependable safety control.
4. Operating Principle
When process pressure enters the sensing chamber, the diaphragm or bellows expands in proportion to the pressure level. This mechanical displacement triggers the microswitch, which opens or closes the electrical contacts based on the preset setpoint.
setpoint adjustment is simple and highly accurate. Once configured, the switch maintains stable performance even under varying load conditions or temperature fluctuations. Hermetically sealed SPDT switching ensures minimal wear and consistent operation over extended service cycles.
