On-off switches are essential components for monitoring and controlling pressure and temperature in industrial and marine systems. These devices operate using a built-in contact system that reacts when a pre-set pressure or temperature level is reached, enabling automatic control, alarms, or shutdown procedures.
Key functions of on-off switches include:
- Regulation of pressure and temperature
- Monitoring system conditions
- Activating alarms
- Emergency shutdown for safety
On-off switches can also work as differential switches, comparing two pressure or temperature values and reacting when the difference exceeds a defined threshold. This makes them highly useful in filtration systems, compressors, and engine monitoring applications.
Danfoss offers a wide portfolio of sensing solutions designed for reliability in demanding environments. These include well-known product ranges such as MBC, KPS, CAS, RT, KP/KPI, BCP, and CS series, each suited for specific applications and operating conditions.
Typical applications include:
- Marine engines and auxiliary systems
- Compressors and pumps
- Boilers and steam systems
- Industrial automation and process control
When selecting an on-off switch, key considerations include pressure range, temperature limits, environmental conditions, and required certifications. Proper selection ensures accurate control, long service life, and safe operation.
