1. Product Description
Tuning fork level limit switch is a common type of level limit switch, excited by a piezoelectric crystal tuning fork.
Reed vibration, liquid or solid when tuning fork is submerged when the vibration frequency changes, the frequency changes by electronic wire
Road detected and outputs a switch. Tuning fork level limit switch from medium electrical parameters and turbulence, agitation.
Bubbles, vibration and other factors, no moving parts, so maintenance and adjustment is a complex condition of level open / off the ideal choice.
