A new angle on rotary feedback

steelindustryTransporting hot materials (ex. steel slabs) from one location to another via a walking-beam is common place in steel manufacturing. In the past, rotary encoders have typically been used to provide the precise feedback of rotary movement for these types of applications. However, optical encoders are prone to failure in harsh environments. Steel mills utilizing walking-beams for material handling have plenty of dirt and particulates in the air as well as produce high shock and vibration. All of these would contribute to an overall harsh environment which would shorten the life of an optical encoder.

Precise position checking and the continuous adjustment of rotational movements are extremely important on the walking-beam. Inclination Sensors are ideally suited for these exact tasks. With contact-free angle measurement, they guarantee maximum precision when the slabs are being transported. Inclination Sensors do not need mechanical coupling in contrast to rotary encoders, are compact and robust, and measure the deviation from the horizontal on an axis of up to 360°.

Angle Sensing & Tilt Detection Solutions

When an application calls for angle sensing or tilt detection there are a few choices including fluid based and MEMS technology Inclination sensors. For this blog entry we will focus on the MEMS technology. MEMS offerings have the option of one or two axis with up to 360° of measuring range. They provide an easy means of directly detecting positions without making contact enabling continuous feedback of rotational movements along the axis. The precise position control and continuous positioning of rotational movements are critical in many applications making them reliable solutions where accurate positioning is a must.

Sensors based with the MEMS technology operate by taking a capacitance differential and converting it to an analog signal. This analog signal is relative to the angle of the sensor in the application. The compact housing sizes are also a great feature offering various mounting options for a wide range of applications.

Inclination sensor typically have  robust IP67 ratings making them ideal for tilt protection for cranes, hoists, tractors, expandable mechanical arms and other types of mobile agricultural machines. The Inclination sensor controls and monitors efficient operation verifying the correct positioning needed for reliable operation.

It is not uncommon to see MEMS style inclination offerings used in the renewable energy market. You can commonly see applications where inclination sensors are mounted directly to a rotating shaft to provide angel feedback for Fresnel Solar Panels.
