Understanding Dual Axis Inclinometers: Background and Applications

Dual axis inclinometers are sophisticated sensors designed to measure angles of tilt or inclination along two planes simultaneously. These devices are crucial in applications where precise angular measurement is required, providing critical data for systems in various industries. This blog post delves into the background of dual axis inclinometers, exploring their underlying technology, and highlights some of their many applications.

Background on Dual Axis Inclinometers

What is an Inclinometer?

An inclinometer, also known as a tilt sensor or level sensor, is a device that measures the angle of inclination or tilt relative to gravity. Dual axis inclinometers extend this capability by measuring tilt in two orthogonal planes, typically labeled as the X and Y axes. This dual-axis measurement allows for a comprehensive analysis of an object’s orientation.

Commonly used in leveling applications, dual axis inclinometers provide simultaneous position information in both the X and Y plane.

How Do Dual Axis Inclinometers Work?

Dual axis inclinometers operate on various principles, including electrolytic, capacitive and MEMS (Micro-Electro-Mechanical Systems) technology. Among these, MEMS-based inclinometers have gained popularity due to their compact size, high sensitivity, and robustness.

Different Types of Dual Axis Inclinometer?

Dual axis inclinometers are available in a wide variety of housing and communication options. Plastic housings are common for OEM and low-cost applications, where metal housings with IP68/69K ratings are available for outdoor and even submersible environments. Inclinometers are also available with certifications for hazardous environments such ATEX, CSA and Intrinsically Safe. Furthermore, b/c the inclinometer is making its measurement with respect to gravity, inclinometers can easily be placed inside an enclosure and anywhere along the moment arm, making installation quick and easy.

As for communication protocols, inclinometers are available with a wide variety of communication protocols including analog 4-20mA and voltage, CANopen, J1939 for mobile machinery and off-highway and ModBus RTU.

Options also exist for ‘static’ and ‘dynamic’ applications. As the inclinometer by definition is making a measurement due to the force of gravity (an acceleration) on the sensor, any other accelerations such as shock or vibration will impact the measurement. ‘Dyanmic’ inclinometers, such as the POSITAL AKS series, rely on the use of an internal gyroscope for position data when the inclinometer is experiencing movement.

Applications of Dual Axis Inclinometers

Agriculture and Forestry

Modern agriculture and forestry machinery, such as tractors and harvesters, benefit from dual axis inclinometers. These sensors help maintain the optimal orientation of equipment on uneven terrain, improving operational efficiency and reducing the risk of accidents. In forestry, inclinometers assist in monitoring the tilt of trees, aiding in safe and efficient logging operations.

Maritime and Marine Applications

Maritime vessels and offshore platforms rely on dual axis inclinometers to monitor their tilt and orientation in the water. These sensors help maintain stability and safety in challenging sea conditions, ensuring the proper functioning of navigation and operational systems. In marine research, inclinometers assist in tracking the orientation of underwater equipment and submersibles.

Conclusion

Dual axis inclinometers are versatile and indispensable sensors with applications spanning numerous industries. Their ability to provide accurate and real-time tilt measurements makes them essential for ensuring safety, efficiency, and precision in various fields. As technology advances, the capabilities of these sensors continue to expand, opening up new possibilities for their use.

Whether in construction, geotechnical monitoring, industrial automation, agriculture, aerospace, or maritime applications, dual axis inclinometers remain at the forefront of innovation, helping to shape a safer and more efficient world.
