Leveltec Tilt Switch

What is a Leveltec Tilt Switch?

When product surrounds or piles against the hanging detector, the probe tilts and changes the switch state. The control system interprets that state according to the required filling, alarm or shutdown sequence.

A complete installation is selected by function rather than product name. Mechanical action, contact behavior, reset method and environmental capability must match the monitored hazard or process condition, while the control circuit determines whether the signal becomes an indication, alarm, interlock or stop.

Typical applications

Common duties include small storage bins, crusher chutes, conveyor discharge points, bulk bag filling. Each location should be surveyed for material impact, buildup, access, vibration, temperature and exposure before the device and bracket are specified.

• small storage bins: verify the actual operating condition, mounting geometry and required response before selecting a model.
• crusher chutes: verify the actual operating condition, mounting geometry and required response before selecting a model.
• conveyor discharge points: verify the actual operating condition, mounting geometry and required response before selecting a model.
• bulk bag filling: verify the actual operating condition, mounting geometry and required response before selecting a model.

How to select the right model

Use a compliance table to compare candidates against the same requirements. Include operating principle, range or travel, contacts, enclosure, temperature, certification and proof-test method so commercial differences do not hide technical gaps.

Create an equipment record containing the full model code, approved datasheet, terminal plan and selected settings. This makes quotations comparable and preserves the engineering basis for later replacement.

• Confirm the contact arrangement, utilization category and control voltage.
• Match the enclosure and ingress rating to dust, water, washdown and corrosion exposure.
• Check ambient temperature, cable entry, mounting dimensions and actuator geometry.
• For hazardous areas, verify the complete certificate and marking for the exact model.

Installation and commissioning guidance

Allow for the material’s angle of repose and the difference between static level and dynamic flow. The probe must remain accessible for safe inspection and functional tests.

Use a rigid, low-vibration support and keep the actuator inside its specified approach and overtravel. Preserve sealing and earthing with compatible glands, then test the signal from the physical device through to the final control action.

Inspection and lifecycle care

Trend nuisance operations and slow or failed resets. Increasing event frequency often reveals a process, alignment, contamination or mounting problem before the device loses its function completely.

Never bridge or restrain a protective device to maintain production. Control the affected equipment, investigate the initiating condition and restore normal service only after corrective work and a successful test.

Specification, commissioning and lifecycle record

A dependable Leveltec tilt switch decision remains traceable from the operating requirement to the installed order code. Record the normal condition, abnormal trigger, required controller state, alarm or stop response, reset rule and inspection method before requesting quotations. This prevents commercial substitutions from changing the engineering function unnoticed.

Keep the approved datasheet, complete model suffix, terminal drawing, mounting sketch, certificates and commissioning result under the equipment tag. After replacement, adjustment, conveyor modification or control-software change, repeat the relevant physical proof test and update the as-built record. The test must demonstrate the field device, wiring, controller indication and final machine response rather than only a changing PLC input.

• Compare complete order codes and option suffixes.
• Confirm contact state under normal, actuated and fault conditions.
• Record the installed clearance, angle, tension, threshold or calibration.
• Inspect mounting, cable entries, seals, earthing and access.
• Set maintenance intervals from risk, environment, duty and failure history.

Frequently asked questions

What is the best mounting height for a tilt switch?

It is the point at which the process must respond, adjusted for material pile shape, probe length and safe clearance from equipment.

Can vibration create false trips?

Severe vibration or an unstable suspension can move the probe. Rigid support, correct location and validated delay settings reduce nuisance operation.
