Milltronics Tilt Switch Probe
The Milltronics Tilt Switch probe is an electro-mechanical tilt switch for point level
detection, plugged chute detection, belt tracking alarm, and feed loss detection on
conveyor belts. Tilt switches also provide simple high and low alarm for both dry bulk
solids and liquids.
The rugged, stainless steel encapsulated probe is suspended vertically over a bin or belt,
and the potted switch inside the probe provides a signal when material tilts it through an
angle of more than 17° from vertical in any direction. The switch will remain open until it
returns to an angle of less than 17°. The probe should be mounted so it can be tilted by
the measured material. Do not mount the probe in the path of falling material as this may
bury or damage the probe or cause erratic switching.
Optional extensions are available for specific applications.
Wear Extension:
replaceable extension used for level detection on
coarse or abrasive materials, belt tracking and loss of
feed on belt conveyors
Cross Paddle:
used in level detection on fine ores or medium bulk
density materials
Flat paddle:
used for plugged chute detection
Float:
used for level detection of liquids or light density
materials
