ZEROMATIC dual-axis inclination sensor
The ZEROMATIC is a high-precision dual-axis inclination sensor for long-term monitoring with a measuring range of ±1°.
The ZEROMATIC dual-axis inclination sensor is perfectly suited to monitoring even the smallest of changes in inclination over longer periods. The excellent accuracy is achieved through regular and automatic reversal measurements, allowing the determination and elimination of any drift of the absolute zero.
The ZEROMATIC sensor has the following features:
- Measuring range: ±1°
- Long-term accuracy: 1 Arcsec
- High-precision mechanics for the automatic reversal measurement
- Rugged precision aluminum housing to minimize external influences
- Data transmission to PC/laptop or to a display unit
- LED, showing the status of the instrument
There are two versions of the ZEROMATIC sensor available: ZEROMATIC 2/1 and ZEROMATIC 2/2.
- The ZEROMATIC 2/1 has one inclination sensor which continually measures either in the X or in the Y direction. When carrying out a reversal measurement, the sensor stops at four positions: +X, +Y, -X and -Y. Afterwards the new exact, absolute inclinations in both X and Y directions are made available. The ZEROMATIC 2/1 is typically used to monitor inclination changes of structures such as dams and bridges, which exhibit only slow changes. The interval between 2 reversal measurements is usually in the range of 15 minutes to 6 hours.
- The ZEROMATIC 2/2 has two inclination sensors, allowing continuous measurements of inclination changes in both the X and Y directions. At defined intervals it will perform a reversal measurement and compensate for any offset. The ZEROMATIC 2/2 is typically used to monitor machine tools or other objects which show considerable changes e.g. due to temperature changes. The interval between two reversal measurements is usually in the range of 3 to 24 hours.
Typical applications are:
- Monitoring of critical machines
- Monitoring of buildings, bridges or dams
- Defining absolute zero references e.g. for radars
wylerSOLID protection case for ZEROMATIC
wylerSOLID is a heavy-duty protection case for ZEROMATIC sensors.
For long term monitoring tasks, ZEROMATIC sensors are often installed at locations with a demanding environment regarding temperature and humidity. Thanks to its robust design with IP 67, wylerSOLID is perfectly suited for such applications.
wylerSOLID is only supplied together with a ZEROMATIC since the mounting of the sensor into the wylerSOLID must be carried out at WYLER AG.
ZEROMATIC 2/1 and 2/2 inclination sensors can be delivered with an internationally recognised Calibration Certificateagainst a surcharge
RECOMMENDATION FOR THE MOUNTING OF THE ZEROMATIC SENSOR
Usually when measurements are done on buildings a rectangular mounting bracket is required. With the ZEROMATIC sensor high precision inclination measurements can be done. It is however important to consider the following recommendations:
Temperature changes may have a great influence on the measured results. All around the ZEROMATIC sensor the same temperature must be applied.
Mechanical tension between the ZEROMATIC sensor and the mounting bracket and/or the anchorage must be avoided, as these tensions are often the cause of unstable values.
THREE-POINT MOUNTING / DESIGN
Whenever possible, use a three-point mounting jig. Use the same geometry and homogenous material all over. Make a „center symmetrical“ design.

MONITORING OF A WATER INTAKE TOWER AT A DAM
The stability of a water intake tower is critical to the safety of a dam. The operator of the dam therefore requests continuous monitoring of the tower’s inclination.
Measuring task / Goal:
The inclination of the water intake tower, that is its change in attitude, is to be monitored and registered continuously. The inclination sensor is to be mounted stationary, and must have excellent zero-point stability. The measuring values are to be registered and evaluated in the central station of the dam at a distance of about 500 m
MONITORING OF A HIGH RACK WAREHOUSE
Automatic high rack warehouses can reach very large dimensions:
80 m length, 45 m width and 30 m height are no exceptions. Despite these dimensions and despite the high speed of the transportation system, each bin must be placed very accurately at its predefined location. In order to reach such accuracy, the alignment of the racks is of key importance. The exact verticality of each rack has therefore to be ensured. Already smallest deviations will change the distance to the transportation system and could cause errors. The bins could get blocked and get damaged or even fall.
Measuring task / Goal:
The verticality of each rack in the high rack warehouse must be monitored permanently.
MONITORING OF 6 TOWERS AT A DOUBLE SLUICE
The sluices are over 100 years old and consist of two parallel sluices. The vertical gates put a heavy strain on the six towers, which is the reason why continuous monitoring is required.
Each of the six towers should be permanently monitored with suitable inclination sensors along the X- and Y-planes. The measuring values should be transmitted online to the local water authority, thus facilitating to alarm in a timely fashion.
MONITORING OF SYNCHROTRONS
The requirements regarding long term monitoring of dams are continuously increasing. Where it was enough earlier to carry out periodic measurements, today more and more permanent monitoring is required.
The changes in inclination in both directions (mountain <-> mountain and water <-> air) of a dam shall be monitored continuously.
