Ihre Bauteil-Auswahl:

Component type

Please select a component type that comes closest to your component. However, the selection is purely for visual support of the input steps and has no influence on the calculation result. In addition to the component types shown as examples, other shapes are of course also possible on request.

Energy supply

Please select the desired design of your integrated sensor unit with regard to the power supply.

Material

Please select the material your component is made of. If the appropriate material is not included, you can note this in the comments column of the request.

mm

Component length L

Select your component length. In the diameter range up to 24 mm, the minimum length is 160 mm. For larger diameters, a component length of >= 80 mm is possible.

mm

Inner diameter

The component is hollow or has a through or blind hole. Our sensor is integrated in this area. The minimum inner diameter is 14 mm. Other standard sizes are Di=14 mm, 30 mm, 44 mm, 52 mm, 54 mm, 72 mm.

In the range of the sensor
mm

Outer diameter

The outer diameter is at least 2 mm larger than the inner diameter (wall thickness >= 1 mm).

Distance A (sensor / load introduction)

Describes the distance between the nearest load application point (e.g. the clamping coupling of a torque measuring shaft or the contact surface of an axial force sensor) and the center of the sensor element - i.e. exactly at the height at which measurements are to be taken.

mm

Distance B (sensor / component edge)

Describes the distance between the nearest component edge and the center of the sensor element, i.e. exactly at the height at which measurements are to be taken. Placing the sensor as centrally as possible is ideal in order to achieve a homogeneous strain distribution at the sensor.

Measured variable A:

Measured variable

Select the desired load types of your sensor. By default, 2 measurement types can be realized in one sensor component.

Nominal range

The nominal range defines the maximum force or the maximum torque that occurs in nominal operation. Our sensors are overload-proof and can also withstand larger load peaks without any problems. The nominal range should therefore be as close as possible to the actual measuring range in order to achieve the best possible sensor performance.

Performance Measure A:

Nominal range
Signal to noise ratio

Signal to noise ratio

The signal-to-noise ratio (SNR) indicates the relationship between the measuring range and the signal noise. The higher this value, the less noisy the signal, or the finer the resolution. The lower limit is application-specific, but as a rule the value should be at least 50 - 100. Example: With a 100 Nm sensor and a SNR of 200, the noise margin of the unfiltered signal is 0.5 Nm. Furthermore, the signal can be resolved even more accurately if an additional (low-pass) filter is used.

Typical accuracy

Typical accuracy

The typical achievable accuracy is an approximate guide and can vary greatly from application to application. Among other things, the accuracy depends on the load introduction: This causes inhomogeneities in the strain field of the component, which has a negative effect on the accuracy of the sensor. The further away the load introduction is from the sensor, the more homogeneous the strain distribution becomes and a higher sensor accuracy is achieved.

The material used also has an influence on the accuracy of the sensor, as there is hysteresis due to the material. For typical precision tubes in the drive train, aluminum alloys are generally better suited as sensors than mild steel tubes.
