Electronic Tuning Fork Level Switch LS250

Principles characteristics

LS200 tuning fork level limit switch is a universal level limit switch. Inspired by piezoelectric crystal a tuning fork produces an oscillation, when the tuning fork is liquid or solid immersion vibration frequency change, change the frequency by the electronic circuit electric parameters detected from the media and the turbulent, agitation, bubble, vibration, the influence of such factors as no moving parts, so no maintenance amount adjustment, is a complex mixed material level switch under the condition of ideal choice.
