Technical specifications for inclination sensors analog LEVELMATIC, WYLER AG is the leading manufacturer of inclination sensors

There is an increasing demand for high precision inclination sensors to monitor machines or objects like buildings, bridges or damns over longer periods of time. WYLER AG is offering two types of sensors for this purpose:

The analogue sensor LEVELMATIC 31, which allows an easy connection to any measuring system, as it provides a standard voltage output between –2V and +2V proportionally to the inclination
The digital sensor ZEROTRONIC. Due to its digital bus it allows an error free transmission of measurement values over long distances. Furthermore its special measurement concept allows, within certain limits, to measure „dynamically“

The LEVELMATIC sensor 31 is an anlog sensor with an anlog output signal (see specification). This sensor has specifically been developed to be mounted on machines. Since the sensor is mounted in a tight, weatherproof and shockabsorband housing, inclination measurements are possible even under difficult conditions. The distance between the sensor and the indication unit should not exceed 15 m. The application of the sensor is easy.

Measurement principle (similar to MINILEVEL NT + LEVELTRONIC NT):

The LEVELMATIC sensor is based on the pendulum properties of a friction free supported disc of a mass weighing less than 1 gram. A two-phase frequency (2.9 kHz) is supplied to two electrodes, which together with the pendulum disc supported in the shielded and dust proof 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, even overhead measurements are possible.
The shielded sensor and the capacitive measuring principle make the system insensitive to magnetic and electric fields. With this pendulum system extremely accurate results regarding repetition and hysteresis combined with very short reaction times has been achieved.

Execution:
Sensorhousing in cast iron, cromium plated with rubber sealing

Applications:

Levelling of a platform
Inclination measurement on bridges or buildings
Supervision of machine tools
Levelling of machines
etc.

Remark:
More and more the analog LEVELMATIC sensor are replaced by the digital sensors ZEROTRONIC. Besides being more accurate ZEROTRONIC sensors have a more compact design and provide a digital output signal which allows further treatment with various software.
