OPTISWITCH Vibration Level switches

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. 

• 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. 

• Universality: Can be used in many industries and suitable for almost all types of media, including liquids and solids.
• Cost-effectiveness: Provides a cost-effective solution for simple level detection.
• Reliability: Offers reliable and accurate level monitoring in a wide range of applications.
