The SLM series tuning fork level detector has no moving parts and requires no calibration. The High/Low selection feature is available as a standard feature unlike the instruments from other manufacturers. The SLM level switch is insensitive to material build-up and isn't affected by the electrical properties of the service material. You can choose an enclosure depending on you process plant conditions.We have housing that prevents and protects it from explosive conditions, dusty areas and unpredictable weather conditions. What else, we also have a circular enclosure available if you need.
Principle of Operation:
A top or side mounted, stainless steel made tuning fork is kept in mechanical vibration at the resonance frequency by piezoceramic elements. When the service material covers the tines of the tuning fork, vibrations are damped. This is sensed electronically and processed signal is used to energize a relay whose contacts in turn are used for annunciation or control. Two basic type of constructional arrangements are available. One, where the electronics is separated from the fork, the other has them integrated.
You can choose from:
Mounting arrangement of your choice (screwed or flanged type)
Various standards of the mounting according to plant conditions
High temperature versions up to 200 °C without the necessity of elaborate cooling arrangements
