Improper installation of tuning fork level switches can lead to false readings, equipment damage, and costly process interruptions.
Install tuning fork level switches vertically in a location free from agitation, away from fill points, and with proper clearance from vessel walls. Ensure correct orientation and mounting angle.
Tuning Fork Level Switch Installation
Let me share my installation expertise gained from numerous industrial applications.
How Does a Tuning Fork Level Switch Work?
Understanding the working principle is crucial for proper installation and reliable operation.
The tuning fork vibrates at its natural frequency until contact with material dampens the vibration, triggering a switch output. This simple principle makes it highly reliable.
