Measuring principle analog
Measuring principle "analog"
By looking for new applications of levels at WYLER's the electronic inclination instrument was developed. The goal was to develop an instrument which fulfilled the requirements of the market regarding higher resolution, repetition and precision. The instrument should be handy, simple in use and work professionally under rugged working conditions.
The electronic levels with a capacitive measuring system are based on the measuring values on the pendulum properties of a friction-free supported disc weighing less than 1 gram. A two-phase frequency (4.8 kHz) is supplied to two electrodes which, together with the pendulum disc supported in the shielded and dustproof gap between them, build a differential capacitor. The inclination signal is created at the pendulum. Due to the perfect rotational symmetry of the sensor, inclinations perpendicular to the measuring axis are of insignificant influence to the measurement, and even overhead measurements are possible. The shielded sensor and the capacitive measuring principle make the system impervious to magnetic and electric fields. With this pendulum system, extremely accurate results regarding repetition and hysteresis, combined with very short reaction times, have been achieved.
With this pendulum system extremely accurate results regarding repetition and hysteresis combined with very short reaction times have been achieved. The major group of measuring instruments based on the analogue technique consists of MINILEVEL A10/MINILEVEL NT A11 and the LEVELTRONIC A40/LEVELTRONIC NT A41.
