Atmi Tilt Switch

What is a ATMI Tilt Switch?

The probe is suspended at the target point and operates when surrounding material forces it away from vertical. Different probe constructions and approvals address standard industrial and potentially explosive dust environments.

Model suitability depends on the full duty: what changes physically, how quickly it develops, which output is required and what the machine must do next. Two similar housings may differ in contacts, travel, latching, materials or certificates.

Typical applications

Common duties include powder silos, chute plug alarms, stockpile limits, conveyor transfer points. Each location should be surveyed for material impact, buildup, access, vibration, temperature and exposure before the device and bracket are specified.

• powder silos: verify the actual operating condition, mounting geometry and required response before selecting a model.
• chute plug alarms: verify the actual operating condition, mounting geometry and required response before selecting a model.
• stockpile limits: verify the actual operating condition, mounting geometry and required response before selecting a model.
• conveyor transfer points: verify the actual operating condition, mounting geometry and required response before selecting a model.

How to select the right model

Separate mandatory characteristics from preferences. Contact utilization, positive opening, hazardous-area approval and permitted mechanical travel can be critical, while color or a familiar housing shape normally is not.

Document response time, proof-test method and the person responsible for inspection. These lifecycle requirements often distinguish a maintainable solution from one that is difficult to verify in service.

• 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

Review the manufacturer’s probe orientation and exclusion zones. Avoid locations where normal swinging, vibration or turbulent product flow can repeatedly cross the trip angle.

Protect the unit from routine impact or burial unless it is designed for direct contact. After termination, inspect gaskets and cable entries and record the initial clearance, tension, setpoint or calibration as applicable.

Inspection and lifecycle care

Inspection combines condition and performance. Compare the field setting with the commissioning baseline, operate the device safely and record the input, alarm, trip and reset results under its unique tag.

If the device is damaged or its state is uncertain, replace it with a verified configuration and inspect the target or process condition that caused the damage. Like-for-like replacement alone may reproduce the failure.

Specification, commissioning and lifecycle record

A dependable ATMI 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

Can an ATMI tilt switch detect both high and low level?

It can support either point-level function depending on installation and control logic, though the safe failure response must be designed for the application.

Is ATEX approval automatic for every model?

No. Hazardous-area suitability applies only to exact certified variants and markings; verify the certificate, zone, dust group and temperature information.
