Tilt Switch

Tilt Switch is a point-level detection sensor that is generally used for upper limit detection of bulk solid materials by the mechanical tilting of a sensing probe. When bulk solids contact the probe, the probe tilts from its normal position, actuating an internal switch to provide an ON/OFF level signal.

The robust structure ensures reliable detection for lump materials which may get damage for a rotary paddle switch or capacitance level switch.

The gravity-based mechanical operating principle is not affected by material adhesion or buildup and ensures stable level detection.

Stable detection for such material which dielectric constant is low or varies and may make the detection by a capacitance level switch unstable.

The sensor part is fully enclosed in the robust diecasting probe and has high durability against physical shock, material adhesion, high temperature, dust, vapor, etc.

Standard tilt switch is applicable to bulk solids which particle size is 30mm or over and bulk density is 1.0 or over.

Cross paddle option is ready for bulk solids lower than bulk density 1.0 (but over 0.6).

Simple principle by the mechanical tilting of the probe is free from any troubles caused by electrical characteristic of material such as dielectric constant, conductivity, etc.

Tilt switch operates on a simple mechanical principle using gravity.

The sensing probe is suspended in a normal vertical position and the conduction between A-B is close circuit (NC).

When bulk solid material reaches the probe, the material exerts a force that causes the probe to tilt and the conduction between A-B becomes open circuit (NO).

When the material level falls, the probe returns to its original position by gravity, resetting the switch.
