Simple sensor integration into nearly any environment

Inertial sensors from SICK unite reliability, high performance and compact design. From stationary applications to mobile machines: Various interfaces such as analog interfaces, CANopen or SAE J1939 facilitate precise sensor integration in a wide range of applications, machine designs and system environments. All interfaces can be parameterized. In addition, SICK offers shock-resistant housing variants made of aluminum or plastic for its inertial sensors.

Space-saving sensors

The compact sensor design allows for easy integration into applications with limited space. The TMS/TMM22 is only 38.8 mm x 30 mm x 10.4 mm in size. The TMS/TMM61 is also, for example, available with housing dimensions 68 mm x 36.3 mm x 20.7 mm.

Application-specific programming

The sensors can be programmed specifically to the application via the various interfaces or the PGT-12-Pro hand-held programming device.

Simple connection to machine controllers

In addition to common connection types such as straight and angled M12 male connectors as well as open stranded wires, SICK also creates special designs upon customer request.

Rugged housing variants

Inertial sensors from SICK are available in aluminum and plastic housings. They are highly resilient and provide optimal protection for the electronics, making them suitable for numerous application requirements.

Different sizes, interfaces, and housing variants: The portfolio of inertial sensors from SICK offers a suitable solution for nearly every task and installation situation.

Precise inclination measurement for all dimensions

In order to obtain reliable tilt values, interference caused by vibrations or acceleration movements must be filtered out reliably. High-precision capacitive MEMS sensors are wear-free. Digital filters help them determine the correct inclination. This permanently ensures the high resolution and measurement accuracy of the inertial sensors. SICK offers solutions with single- or dual-axis measuring ranges.

One- or two-axis inclination determination

Inertial sensors from SICK are available as one-dimensional solutions with a measuring range of 360° as well as two-dimensional solutions with a ± 90° scope of measurement.

Reliable interference suppression

High-performance digital filters stabilize the measurement signal and ensure reliable inclination values by filtering out interference from the signal. A low-pass filter suppresses vibrations that exceed a previously defined cut-off frequency.

Parameterizable zero point

The preset function allows the user to conveniently zero the sensor. This considerably speeds up and simplifies sensor integration at the customer site.

Interference-free dynamic inclination measurement

In mobile applications, the inclination can be reliably determined in spite of acceleration movements. A sensor fusion algorithm combines the measurement signals from the acceleration sensor and the gyroscope so that the sensor transmits a stable inclination signal to the system.

Innovative MEMS technology and powerful digital filters generate a reliable and stable inclination signal that is free from external interference.

Rugged design resistant to dust and moisture

In many applications, inertial sensors are exposed to harsh ambient conditions. Large temperature differences, direct sunlight or water must not influence the quality of the measured values. That it why the electronics of inertial sensors from SICK are fully injection molded or encapsulated. Parameterizable digital filters ensure a constant output signal during operation.

Full protection thanks to encapsulated electronics

To ensure that inertial sensors from SICK are as reliable as possible, their electronics are fully injection molded or encapsulated, depending on the product variant. The products therefore meet criteria of high enclosure ratings up to IP65, IP66, IP67, IP68 and IP69K.

Developed for harsh ambient conditions

Inertial sensors from SICK satisfy strict requirements: The excellent temperature resistance and outstanding UV resistance of the sensors make possible numerous outdoor applications. The rugged sensors even handle high-pressure cleaning in mobile applications with ease.

Reliable output signal

The digital filters of the inertial sensors can be adapted on-site to the respective application. For example, certain frequencies caused by vibrations can be compensated by targeted parameterization of the low-pass filter. The result: An adjusted, stable database.

No matter how demanding the application conditions are, inertial sensors from SICK offer maximum availability and long-lasting precision.

Very high performance in static and dynamic applications

Inertial sensors from SICK show off their strengths in many areas. In mobile applications such as in agricultural and forestry machinery, construction machinery or automated guided vehicle systems, the rugged sensor design and the powerful algorithm for sensor fusion with extensive parameterization options ensure stable measured values. In applications with slow movements, such as the alignment of solar modules, in warehousing applications or in crane and lifting technology, the classic inclination sensors score points with their reliable MEMS technology and high cost-effectiveness.
Determining the inclination of the aerial rescue truck cage In order to be able to transport people steadily and horizontally, the two-dimensional TMM61 inclination sensor detects the inclination of the basket and forwards this regulation information to the superior control unit. Thanks to the compensating cross sensitivity and the configurable vibration suppression, the TMM61 enables precise and reliable positioning.
Parabolic trough – adjustment in CSP power plants In this system, the sunlight is concentrated by using parabolic mirrors. The sunlight, which enters the mirror parallel to its plane of symmetry, is focused along the focal line and is warming up a heat transfer media like oil. The position of the mirror needs to be guided to follow the sun‘s daily path in order to achieve the optimal energy efficiency. Inclination sensors report the actual position of the parabolic mirror to the controller. An inclination sensor which provides very high accurancy even in rough environments can be used to align and adjust the positioning of the parabolic trough.
Tilt angle detection on injection molding machine When connecting the anode block and support, liquid cast iron is used as an “adhesive.” The cast iron is poured from a pot into the space between the support and the anode block using a tilting device. In order to properly pour the liquid iron, it is necessary to know the precise position of the tilting device. The TMS/TMM88 inclination sensor exactly measures the tilt angle of the device. Measurement is done in one or two dimensions. This enables the sensor to also detect deviations in inclination transverse to the tilting axis. Thanks to its aluminum housing with fully-encapsulated electronics, the sensor is insensitive to the harsh ambient conditions.
Measuring ship inclination It is possible to mostly compensate for swells using stabilizers. The TMS inclination sensor registers the ship inclination to optimally align the stabilizers. This ensures that the yacht lies as still as possible in the water. This has several positive effects: A ship position optimally adapted to the driving resistance, meaning a reduction in fuel, and fewer seasick passengers too. SICK’s precise and reliable inclination sensors take care of this.
Measurement of tray inclination in vertical storage systems In vertical storage systems, inclination sensors ensure smooth put away and prevent mechanical damage. The sensors measure the inclination of trays and reliably detect one-sided or uneven loading. An additional advantage: Inclination sensors can be installed optimally even if space is tight.
Solar cell – adjustment of photovoltaics

The inclination sensor of a solar panel system is communicating the actual tilt position of the solar modules to the controller. The TMS/TMM22 range of inclination sensors provides non-contact inclination measurement with precision, even under tough ambient conditions. The sensors are available for one or two-dimensional measurements and offer high availability with fully encapsulated electronics.
