Deskripsi
OPTISWITCH refers to a series of level switches, and an "OPTISWITCH Vibration Level switch" is a device that uses a vibrating fork or tuning fork to detect the presence or absence of liquids or solids in a tank or vessel, triggering a signal when a specific level is reached. These switches are used for applications like overfill protection, dry-run protection, and pump control in various industries.
How it works
- Vibrating Element:
At the heart of the device is a tuning fork that is electrically excited to vibrate at its natural frequency.
- Media Impact:
When the liquid or solid material reaches the fork, it dampens the vibration.
- Signal Trigger:
The change in vibration is detected by the switch, which then sends a signal to the process control system, indicating that the level has been met.
Key applications
- Overfill protection: Prevents tanks from being filled beyond a safe limit.
- Dry-run protection: Protects pumps from running without liquid, which can damage them.
- Pump protection: Prevents pumps from operating in a dry environment.
- Level detection in small vessels: Used in various industries for simple level monitoring in containers and silos.
