1. Applications
Typical applications for the KAS series sensors are:
- inclination limiter (tilt sensor)
- levelling
- inclination
- acceleration
- vibration
Depending on the intended use the best suitable type must be selected. Please contact our product specialists for
information. Phone: +41 44 806 22 00.
1.1 Tilt and levelling applications
Typical applications can be tilt limiters, levelling of machinery, apparatuses or measuring equipment, automatic
levelling of jibs / booms, excavator shovels, platforms etc.
1.2 Inclination and angle measuring
Examples: inclination measuring in measuring equipment like lasers, in vehicles, robots, surgical operation tables,
building and production machinery
1.3 Acceleration measuring
Applications such as shock and crash monitoring, movement monitoring and recording for fitness analysis or
elderly / handicapped persons combined with alert systems, free fall detection, automobile equipment as ESP
(electronic stabilising program) and ABS (anti blocking system).
1.4 Vibration measuring
Applications are for example bearing damage monitoring, Baby monitoring system, theft protection, earth quake
safety switch-off devices.
2 Characteristics / Technology
2.1 Shock resistance of the sensing element
The sensing elements based on capacitive measuring principle feature high precision and high shock resistance,
resulting from the particular 3D micromechanics technology made of high purity silicon. Thanks to the optimized
structure, no drifts caused by deformation must be expected, even after severe shocks.
2.2 Repeatability and long term stability
With SCA61T for instance repeatability up to 0,01° or 0,2mg and long term stabilities of the same order can be
achieved. The hysteresis (e.g. 0,02°) caused by quick temperature changes degenerates to zero within a short
time.
