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.
- No moving parts
- independent of the density of media and electrical parameters
- stainless steel liquid contact parts
- Ac/DC power supply is optional
- Relay output
- can be used for solid or liquid measurement
- two electronic heads available (compact/rugged)
Product application
Hydraulic/lubrication/pump protection/cooling system /pulp water treatment/food and beverage
