TWK's Inclination sensor NBT/S3 uses micro-electro-mechanical-system (MEMS) sensors to measure the inclination of a vehicle. The sensor features a stable aluminum housing, which is also offered in stainless steel, making it highly resistant to vibration and shock. The IP69K-rated sensor includes a redundant MEMS sensor system for plausibility checks. If the deviation of the two systems is higher than a set value, the sensor enters a failsafe state. The NBT/S3 has the safety certifications SIL2/PLd and works with the PROFIsafe over PROFINET interface.
