– Crane Truck

China INC60M High Accuracy Dual Axis Tilt Sensor supplier has been widely used in solar tracker system

Solar tracking arrays rely on sensors, which feed angular position to condition monitoring and SCADA systems possible. Tilt sensors (also named as inclinometers) are one of the more critical sensors and tell controllers the tilt angle of panels or a solar concentrating device. The tracking system is the only component that will increase a solar power system’s productivity. The tracking system would consist of a tilt sensor and a controller. The tilt sensor sends position feedback to the system and the controller is used to reposition and adjust the panel’s position so that they are receiving the most possible sunlight. Tracking systems are ideal for power grids that are restricted to a limited amount of space and to optimize large-scale grids as well.

INC60M RS485 Modbus RTU tilt sensor is specially designed for solar tracker systems, it enjoys ultra-low cost (which can assure big scale using), small size, little power consumption, with IP67 protection level, and qualified cable, which is suitable for outdoor applications, and it has been widely used in hundreds of solar power plants around the world.

We can also provide custom service for you to enable better system integration and lower cost. Whether you are designing a new Solar Tracker, or want to consider alternative sensors, we can offer the best solution for your application.

INC60M RS485 Modbus RTU inclinometer has been widely used in Crane Monitoring

Before mobile cranes can be safely operated it is necessary to level and steady the base within a certain tolerance, and when installed on a crane, an inclinometer – also known as a tilt sensor –measures the angle of slope or tilt of an object with respect to gravity. This instrument makes it possible to prevent snags, enables a hoist to lift a load straight up, and reduces and controls load sway.

SkyMEMS is dedicated in the design and manufacture of inclinometer sensors for measuring angles and have developed different series of inclinometers with different output interfaces. We have many types of inclinometers with competitive price and performance levels suited for crane monitoring applications.

INC60M RS485 Modbus RTU inclinometer has been widely used in cradle monitoring

Inclinometers and tilt sensors or tilt switches are vital here as the cradle must be level, steady with their base and stable when carrying heavy loads to be safely operated. It is also necessary to continuously monitor these angles when in use to ensure they do not become unstable, or exceed their safe operational limits. Inclinometer sensors used in such environments should be tough and reliable, as well as being compatible with different output types.

It is vital that the cradle in aerial man lifts supporting the operator is kept level. Our low-cost inclinometer sensors are highly suited to this application to provide angular position feedback to the hydraulic control system which in turn can adjust the angle of the cradle.

Q: Why INC60M tilt sensor is the right selection for solar tracker systems?

A: INC60M is specially designed for solar tracking systems, it enjoys tiny size, very low cost, easy to be integrated into the solar tracking system, and with IP67 protections, and have been widely used in the solar tracker systems, these factors make INC60M is the right tilt sensor for solar tracker systems.

Q: What is the difference between the static inclinometers and dynamic inclinometers?

A: The static inclinometers are equipped with a 2D MEMS accelerometer serving as a sensor cell. This type of inclinometer allows high precision to be achieved in a static system, or when the machine only performs slow movements.

And the dynamic inclinometers (also called as vertical gyros) are equipped with a 3D MEMS accelerometer and a 3D MEMS gyroscope. An intelligent algorithm combines the signals from the accelerometer and the gyroscope to eliminate the effect of accelerations (e.g. due to rapid movement of equipment), vibrations and shocks.

And INC60M inclinometer belong to static inclinometer, which can provide high accuracy tilt angle in a static system or slow movement applications.

Q: What factors affect the accuracy of the inclination sensor

A: the inclinometer’s accuracy is related to installation errors, zero offset errors, and non-linearity errors.

Q: How to calibrate the inclinometer?

A: The inclinometer needs to be calibrated on a high-precision turntable, and then the obtained data is used to perform algorithmic compensation on the inclination sensor. At the customer side, if there is no precision turntable, it cannot be calibrated, we can provide inclinometer calibration service.

Q: How to protect the INC60M inclinometer components from failure?

A: The INC60M inclinometer is mainly used for measurement in a static environment or similar static environment. It adopts IP67 protection, and the device will not fail in normal use.

Q: What factors affect the actual accuracy in the applications?

A: the inclinometer actual accuracy will be influenced by the following factors:

1). The accuracy is mainly affected by the installation error. Since the installation error is inevitable, during the installation process, install as much as possible according to the installation method. If the installation axis of the inclination sensor is parallel to the two sides of the inclination sensor, then the installation error is almost a constant value. The influence of installation error can be removed by measuring relative error.

2). Temperature, the environment temperature change has an impact on accuracy

3). Zero bias error

4). Non-linearity error

5). It will be related to the g value, but it has little effect. It is related to the latitude used. If possible, please tell us the latitude that the inclinometer is used. We will write this value into the inclinometer during the calibration process to reduce the error.


Q: What is the Measurement Principle of MEMS Inclinometers??

A: Inclinometers measure the orientation angle of an object with respect to the force of gravity. This is done by means of an accelerometer, which monitors the effect of gravity on a tiny mass suspended in an elastic support structure. When the device tilts, this mass will move slightly, causing a change of capacitance between the mass and the supporting structure. The tilt angle is calculated from the measured capacitances.

The function can be illustrated with a simplified model with two electrodes: one fixed, and the other (the proof mass) is movable, suspended by spring elements. When the inclinometer is in a horizontal position, the capacitance between the electrodes is measured. If the sensor is tilted, the movable mass and its electrode will change position relative to the fixed electrode. This resulting change of capacitance between the two electrodes is measured by the sensor cell and used to calculate the new inclination value.

Q: What is the Limitations of Static Inclinometers?

A: In case of strong shock and vibration, the physical damping in static inclinometers might not be sufficient to suppress disturbances. Software filters can only help to a limited extent in reducing the impact of such disturbances. For static inclinometers, “moving average” or “exponential” filters can be activated and configured to smoothen the signal, but with the downside that the fast reaction time of the MEMS inclinometer is lost and the response of sensor becomes slower.

For dynamic movements with strong accelerations, SkyMEMS’s Dynamic inclinometers (named as vertical gyro) should be used. They are based on a different technology without physical damping so that there is no tradeoff between stability and response time.

Q: What is Data Processing of MEMS Inclinometers?

A: A high performance microcontroller is used to evaluate the sensor signals in real time and calculate the corrected slope angle. Temperatures are also measured and used by the compensation algorithms to correct for unwanted effects. Intelligent digital filter algorithms reduce ambient noise and vibration to provide a precise and stable signal under all environmental conditions.

Non-linearities in the MEMS sensors are identified through a series of reference measurements made during the production process. These non-linearities are stored as a set of calibration data within the sensor. During operation, the calibration data are used to correct the MEMS sensor raw values and output an accurate linearized tilt angle. Customized parameters like an offset correction (Preset) and a scaling function (in case of analog output signals) can be added by the customer.

Q: What is Dynamic Inclinometer?

A: For applications where sudden movements, shocks and vibrations are likely to be encountered, it is important to have sensors with fast response and a clean signal output. SkyMEMS’s dynamic inclinometers combine two measurement principles using two different MEMS sensors: a 3D acceleration sensor and a 3D gyroscope. The 3D acceleration sensor is not damped (unlike the units used in static inclinometers) and can follow rapid dynamic motions. At the same time, the 3D gyroscope measures rotational speeds, based on inertia principles. Signals from the accelerometers and gyroscopes are combined to produce an inclination measurement that fully compensates the effects of accelerations. As a result, dynamic inclinometers can be used reliably on mobile equipment such as construction machinery, mining equipment, cranes or in robotic applications.

Q: whether the connector and cable length can be selected?

A: yes, no problem, please let us know the connector type and cable length you want, then we can do it.

Q: How about the delivery time?

A: for our standard model, if we have them in stock, only need 2~3days to re-test before shipping, if it is out of stock, then need around 2 weeks to arrange the production and tests. For the ODM electronic product, if needing to modify the structure, it will need around 3~4 weeks to arrange the production and tests.
