Measuring System for SLM Vibrating Fork Level Switch:

The fork is either side or top mounted on the vessel. Two basic types of constructional arrangements are available. In one, the electronics is separated from the fork, whereas in the other, it is integrated. Mounting arrangements of screwed or flanged type, high temperature models up to 200°C and flameproof versions for hazardous areas are available. Longer probe lengths require pipe extension made of GI or SS. Integral version meant for higher temperature operations are provided with stand­off arrangement for keeping the electronics in a relatively cooler environment. Adjustable probe length is provided with gland arrangement. A specially shaped tuning fork is kept vibrating using piezo-electric elements. The oscillation of the fork damps when in contact with the material. The loss of oscillation amplitude is detected and used for switching a relay. The output contacts of the relay are in turn used for annunciation or control.
