DAS : High Resolution Inclinometer, ±10, ±30 or ±90°, 0.5-4.5V Out

Product catalog summary

Specifications
The DAS High Resolution Inclinometer is available in three measuring ranges: ±10°, ±30°, and ±90°, with a supply voltage of either 5Vdc or 9-30Vdc. It operates within a temperature range of -40 to 85°C and has an operating current of 5mA. The device features a high-resolution analogue output voltage ranging from 0.5-4.5V, with a non-linearity of 0.5% and a resolution of 0.001° at 3Hz bandwidth. The sensor is housed in a compact, robust aluminium casing measuring 46 x 43.5 x 13.5mm and weighing 90g including the cable.

Features
The inclinometer incorporates a dual-axis 3D MEMS sensor, providing high-resolution output without digital conversion. It is CE certified and manufactured in the UK. The device is sealed to IP67 standards and comes with a 2m screened PUR cable, extendable upon request. It is designed for low-cost, high-performance applications.

Applications
Typical applications include position feedback for solar tracking systems, platform levelling, GPS compensation, tilt monitoring for agricultural and industrial vehicles, and robotics position sensing. The device can be customized for various applications.

Performance and Calibration
The inclinometer's output is a sine function of the angle, with linearity around the zero position. Sensitivity decreases as the angle approaches 90°, affecting measurement accuracy. Temperature changes can impact zero position and sensitivity, with graphs provided to illustrate typical and worst-case scenarios.

Cable Details
The cable consists of tin-plated copper wires with polypropylene insulation, a braided screen, and a black PUR solar jacket. It is flame retardant, UV stable, and suitable for outdoor use. The cable has a voltage rating of 600V and a core current rating of 2A at 40°C.

level developments DAS : High Resolution Inclinometer, ±10, ±30 or ±90°, 0.5-4.5V Out Description This sensor incorporates a high performance dual axis 3D MEMS sensor. The analogue output voltage varies from 0.5-4.5V over the range of the sensor and is derived directly from the sensor without any digital conversion, so it gives a very high resolution output. It is packaged in a small, robust, sealed Aluminium housing and is supplied with a 2m screened PUR cable (longer on request). There are three measuring range options, ±10°, ±30° or ±90°, and two options for supply voltage level, either 5Vdc or 9-30Vdc. These sensors are CE certified, and are manufactured and tested in our UK factory. • Measuring range : ±10°, ±30° or ±90° dual axis • Sealed to IP67 • Solid state 3D MEMS sensor • Braided screen 4 core cable, 2m standard length, others on request • High resolution 0.5-4.5V analogue voltage output directly from sensing element • Low cost relative to performance • Small size, 46 x 43.5 x 13.5mm Typical Applications • Position feedback for solar tracking systems • Platform levelling and monitoring • GPS compensation • Agricultural and industrial vehicle tilt monitoring • Telescopic and scissor lift platform monitoring • Robotics position sensing • Can be readily customised to suit most applications Specifications Parameter Level Developments Ltd.

All inclinometers measure a change in gravitational field to derive angle. As the inclinometer sensor is rotated, the sensing element is subject to gravitational forces which move the proof mass, and this movement is detected and converted to a voltage. In this sensor the output is linear with the change in acceleration (g), which means that the output is a Sine function of the change in angle (°). The graphs below show the output voltage vs. angle. The formula to calculate the angle from the voltage is given by : (Vout-Voffset) Sensitivity Where : Vout = Measured voltage from the sensor Voffset...

level developments DAS : High Resolution Inclinometer, ±10, ±30 or ±90°, 0.5-4.5V Out One of the largest effects on accuracy for any inclinometer sensor is the effect of temperature. A change in temperature can cause a shift in the zero position (known as zero bias temperature error) as well as affecting the overall sensitivity of the device (known as sensitivity temperature error). The graphs below show the performance of typical and worst case devices for these two errors. Cable Details 1.
