Choosing an Inclination Sensor for Mobile Equipment: 5 Questions OEMs Should Ask

1 – What does the machine need to measure?

Start with the application. What angle needs to be measured, and how will the machine use that information?

Monitoring chassis tilt may require different specifications than measuring the position of a moving machine structure. Your team needs to establish the required measuring range, whether the application needs one or two axes, and the accuracy the machine actually requires.

Resolution and accuracy also deserve separate attention. A sensor’s ability to report small changes does not, by itself, establish how closely its readings match the actual angle.

Consider when the measurement matters: while the machine is stationary, during movement, or throughout an operating cycle. That distinction belongs in the initial requirements discussion because it helps the supplier understand the conditions behind the specification.

2 – What conditions will the sensor experience?

A sensor mounted inside a protected enclosure has a different working environment from one exposed on a machine frame.

Think about the full operating cycle. Where will the sensor encounter vibration, shock, temperature changes, moisture, dust, or washdown? Could its location expose the housing, connector, or cable to damage during normal operation or maintenance?

Environmental ratings are useful, but you need to evaluate them against the actual installation. Review the sensor’s operating limits, mounting requirements, and connection details together.

This is also where field service can contribute valuable information. Technicians often know which locations collect water, where cables are under strain, and which components are difficult to access. Bringing that experience into selection can help the engineering team identify concerns before production.

3 – How will it integrate with the existing machine?

A sensor can meet the measurement requirements and still require significant integration work.

Check the available mounting space, orientation, connector, pin assignment, supply voltage, and communication requirements. If the machine uses CANopen, for example, confirm the specific interface and configuration requirements with the supplier.

Then look at how the machine will use the data. What calibration or zero-setting procedure is needed? What software changes might be required? How will technicians configure or replace the sensor in the field?

These details help establish whether a standard product fits the application or whether an adaptation is worth exploring.

The earlier you discuss them, the easier it is to understand the development effort before committing to a component.

4 – What must be verified when replacing an existing sensor?

When a component becomes obsolete, finding something with similar specifications is a useful starting point. Compatibility still needs to be established.

A replacement review should account for mechanical fit, electrical connections, communication behavior, measurement performance, and the machine’s response to the new sensor.

Document what needs to stay the same and where changes are acceptable. Include both production machines and equipment already in service. A change that is manageable on the assembly line may create additional work for technicians supporting older machines.

Ask the prospective supplier what information they need to assess the application and what validation will be required. Treat “drop-in replacement” as a conclusion to verify through engineering review and testing.

5 – What support will you need after production begins?

Sensor selection is also a supplier decision.

Purchasing needs to understand availability, production capacity, and how product changes will be communicated. Engineering needs access to documentation and people who can help resolve integration questions. Field service needs a practical path for troubleshooting and replacement.

Discuss those expectations early. Ask how the supplier supports validation, handles technical questions, and plans for the component’s lifecycle.

The goal is to select a sensor your organization can build with, maintain, and support over time.

Start with the machine requirements

At MOBA, we work with OEMs to understand the application behind the component. That includes the operating environment, integration constraints, production needs, and people who will support the machine in the field.

Depending on the requirements, the right approach may be a standard sensor, an adapted configuration, or a broader engineering discussion.

If you are selecting an inclination sensor or replacing an existing component, bring us your machine requirements and the challenge you need to solve. We can work through the options together.
