ZEROTRONIC DIGITAL SENSOR FAMILY

The sensors of the ZEROTRONIC family have a digital inclination sensor and a digital data transmission. Working digitally, they provide the option to compensate for temperature changes and allow data communication over long distances without any loss of data.

The combination of all these features ensures that theses sensors fulfill highest requirements regarding precision, resolution and temperatur stability.


ZEROTRONIC sensors have established themselves in the market as the benchmark when it comes to high-precision inclination measurement in demanding applications.

The ZEROTRONIC family of sensors features the following characteristics:
 - High resolution and high precision

 - Excellent temperature stability
 - Measuring ranges of ±0.5 to ±60 degrees
 - Synchronized registration of measuring values for several sensors
 - High immunity to shock
 - High immunity to electromagnetic fields                        

Choice of two sensor types depending on the application:
 - ZEROTRONIC 3 (former name Type 3)
 - ZEROTRONIC C (former name Type C)

Common characteristics of the two sensors:
 - The outer dimensions and the electrical characteristics are identical.
 - The measuring element is based on a pendulum swinging between two electrodes. Depending on the inclined position of the system, the pendulum will change its position in relation to the electrodes and in so doing, the capacitance between the pendulum and the electrodes will change. The change of these capacitances is measured digitally.
 - The sensor cell is completely encapsulated and thus protected against changes in humidity.
 - Both sensors are calibrated over the complete measuring range with reference points stored in the EEPROM of the sensor.
 - Both sensors are equipped with a temperature sensor and are temperature calibrated allowing an excellent compensation for temperature changes.

Difference in characteristics of the two Sensors:
 - The pendulum of the ZEROTRONIC 3 is larger, which provides a significantly better signal-to-noise ratio for smaller inclinations. The ZEROTRONIC 3 is therefore better suited for high precision applications where only small inclinations are measured.
 - The mass of the pendulum of the ZEROTRONIC C is smaller than the one of sensor Type 3.  This provides a higher stability if the sensor is permanently inclined.
 - Only ZEROTRONIC 3 provides the option of analog output.

The following list of characteristics should allow a proper differentiation and proper application of the 2 sensors:

ZEROTRONIC 3
 - High resolution, high precision for inclinations up to 10°
 - Excellent signal-to-noise ratio
 - Excellent repeatability
 - Excellent linearity
 - Excellent temperature stability

ZEROTRONIC C
 - Excellent precision for inclinations between 10° and 60°
 - Excellent repeatability
 - Excellent long-term stability in inclined position
 - Excellent linearity
 - Excellent temperature stability

Some typical applications for the ZEROTRONIC 3
 - Applications in which high precision and high resolution is first priority, and where only small inclinations are measured:
 - Adjustment of machines (e.g. pitch and roll)
 - Precise adjustment of absolute zero
 - Precise measurement of small inclinations in a heavy duty environment; e.g. exposure to outside temperature

Some typical applications for the ZEROTRONIC C include
 - Larger inclinations
 - Applications in which the sensor remains in inclined position over a longer period of time
