Industrial tilt angle measurement systems – precise inclination measurement for industrial applications
Industrial tilt angle measurement systems are used for precise measurement and monitoring of tilt angles in machines, systems, vehicles, and structures. They are used to determine positions, align platforms, monitor safety functions, or reliably detect movements and changes in orientation.
Tilt angle measurement is required across a wide range of industries – for example in mechanical engineering, automation technology, mobile working machinery, special vehicle construction, or structural health monitoring. Many applications require precise leveling of equipment or continuous monitoring of platforms, work platforms, or machine structures.
The requirements for industrial tilt sensors can vary significantly depending on the application. Factors such as measurement range, accuracy, resolution, temperature range, or mechanical stress play a decisive role. Therefore, each application must be evaluated individually to select the appropriate measurement principle and optimal sensor.
Tilt angle measurement in industrial applications
Tilt angle measurement is a key foundation for many industrial control and monitoring systems. It enables the determination of a machine or system’s orientation relative to gravity and provides essential information for control, safety, and process monitoring.
Typical applications:
- Precise leveling of machines and systems
- Monitoring of work platforms or stages
- Stabilization of mobile machines or vehicles
- Position detection in automated systems
- Safety monitoring in lifting and hoisting systems
Applications are highly diverse. Therefore, it is not possible to define a universal sensor for a specific task. The decisive factors are the specific requirements of the application, such as measurement accuracy, resolution, environmental conditions, and required interfaces for further signal processing.
How industrial tilt angle measurement systems work
Industrial tilt angle measurement systems detect the angle of an object relative to gravity. Depending on the sensor technology, different physical measurement principles are used.
Capacitive tilt sensors
In capacitive tilt sensors, a dielectric is placed between two specially shaped capacitor plates. When the sensor tilts, the capacitance between the plates changes. This change is electronically evaluated and converted into a proportional, linear output signal. Capacitive sensors offer very high accuracy and are particularly suitable for precise industrial applications.
MEMS-based tilt angle sensors
In addition to capacitive sensors, MEMS-based tilt sensors are widely used today. MEMS (Micro-Electro-Mechanical Systems) refers to a manufacturing technology for producing very small mechanical and electronic components in microsystems engineering. Importantly, MEMS describes the manufacturing technology itself, not the specific measurement principle of the sensor. For many industrial applications, MEMS-based tilt sensors are fully sufficient and enable compact, cost-efficient, and reliable measurement systems.
One example is a complete solution developed by Althen for monitoring platform inclination. If a defined threshold is exceeded, potential-free limit value relays switch, enabling automatic activation of safety or control functions.

How to choose the right tilt angle measurement system
Selecting a suitable industrial tilt sensor depends on several technical factors.
- Measurement range
Depending on the application, small angular ranges or larger tilt ranges may be required. - Accuracy and resolution
High-precision positioning tasks require sensors with high resolution and low drift. - Environmental conditions
Temperature, humidity, vibration, or mechanical loads can influence sensor selection. - Interfaces and output signals
Analog signals, digital interfaces, or dedicated control connections may be required for system integration. - Mounting and integration
Design, installation position, and electrical integration also play an important role.

Frequently asked questions about Tilt measuring & switching systems
Answers to the most important technical questions
How are industrial tilt angle measuring systems mounted?
Althen industrial tilt angle measuring systems are mounted directly on the machine, system, or structure whose inclination is to be monitored. A stable, flat, and preferably low-vibration mounting is essential so that the sensor can reliably detect the actual change in inclination.
Depending on the model and application, mounting may be carried out, for example, on a side wall, on a mounting surface, or in a control cabinet or enclosure environment. For single-axis systems, the measuring axis must be correctly aligned with the desired direction of inclination. For two-axis systems, the correct orientation of the X and Y axes must also be observed.
Before commissioning, the installation position, zero point, measuring range, switching points, and electrical connections should be checked according to the datasheet. Environmental conditions such as temperature, humidity, vibration, and mechanical loads must also be taken into account during mounting. Althen supports you in selecting and integrating the right tilt angle measuring system for your application.
What switching points do industrial tilt angle measuring systems have?
The switching points of Althen industrial tilt angle measuring systems with switching function are freely adjustable depending on the model and measuring range. In switching systems such as the NSS1-IP or NSZ1-IP, 2 potential-free relay switching contacts are available. The limit values can be adjusted over the entire measuring range using internal potentiometers. Depending on the version, the measuring range extends from ±3° to ±60° or from 0° to 90°. The switching accuracy is a maximum of 0.5% of the measuring range at 23 °C.
For two-axis applications, the NSS2-M2-IP, for example, provides a total of 4 potential-free relay switching contacts, meaning 2 switching contacts per axis. The switching points can be set internally for both axes and directions. The preferred measuring range here is ±3°, ±5°, or ±10°; other measuring ranges are available on request. Here too, the switching accuracy is a maximum of 0.5% of the measuring range.
The relay contacts are designed for a maximum switching capacity of 30 VDC / 0.5 A. The NSZ1-IP also includes a standard switching delay of 1 second; other delay times are available on request.
For applications involving safety, limit value, or position monitoring, Althen supports you in selecting a suitable tilt angle measuring system with the right switching points, measuring ranges, and output signals.
For which ATEX classes are industrial tilt angle measuring systems available?
Althen also offers industrial tilt angle measuring systems for potentially explosive atmospheres. The NM1-2L-420-ATEX model is available with the marking II 2G Ex ib IIB T4 Gb and is therefore suitable for gas-explosive areas in equipment group II, category 2G.
The version operates with the type of protection intrinsic safety “Ex ib” and is intended for connection to a certified intrinsically safe circuit. It can be used in industrial applications where inclinations must be monitored reliably while ATEX requirements apply.
Which ATEX version is suitable depends on the specific zone, gas group, temperature class, installation situation, and electrical connection type. Althen supports you in selecting a suitable tilt angle measuring system for your hazardous-area application.
