FUNCTIONAL SAFETY SENSOR ■ SIL2 and Performance Level d ■ Number of measurement axes: 1 or 2 ■ Selectable measuring range: ± 5° to ± 90° ■ With preset function ■ Housing: aluminium or stainless steel ■ Protection type: up to IP69K ■ As of hardware version 2 TUV certified Design and function The inclinometer measures the inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. It has a stable aluminium housing (optionally stainless steel) and is highly-resistant to vibration and shock. Casting measures in the housing lead to the achievement of protection class IP 69K. MEMS sensors are integrated circuits manufactured using silicon bulk micromechanical technology. Double capacities are formed with the aid of moveable micromechanical structures. If these structures are deflected in the case of acceleration, e.g. gravitational acceleration (g), this results in capacity changes, which are registered and further processed using measuring technology. The output voltage follows the function U ~ g * sin a. In this case, the angle a is the sensor's inclination angle measured against the g vector. These sensors measure precisely, have a long service life and are very robust. The measuring axes operate independently of each other. The NBT has a redundant MEMS sensor system, which is used to make a plausibility check inside the inclinometer. Only one position datum is output; the plausibility of this is checked using the second system's position datum. Is the deviation of the two systems higher than a certain value, the sensor will enter the failsafe state. The Profinet interface according to IEC 61158 / 61784 or PNO specifications order No. 2.712 and 2.722, version 2.3, is integrated into the inclinometer series NBT/S3. Real time classes 1 and 3 are supported, i.e. Real Time (RT) and Isochronous Real Time (IRT) plus the requirements of conformance class C.The integrated 2-fold switch enables the TWK PROFINET inclinometer to be used in star, tree and line network topologies. The PROFIsafe protocol is implemented according to the PROFIisafe Profile for Safety Technologie version 2.4 (PNO Order No. 3.192). An exhaustive description of integration into a PROFINET network can be found in the NBT13912 manual.

SUPREME SENSORING General description Behaviour in the event of a measured value change due to averaging: Dynamic, arithmetic averaging of the measured values is implemented in the inclinometer. This involves linear averaging over 1000 values, whereby a new value is recorded every millisecond. This results in a low-pass effect. In the event of an abrupt change in the measuring angle, the end value is reached after approx. 1 second. In the event of a linear change in the measuring angle, the relevant output signal follows after a delay of approx. 0.6 seconds. Other, e.g. shorter, values may...
