MEMS inclinometers for precise tilt measurement
MEMS inclinometers are high-precision sensors for measuring tilt angles and changes in position. They are based on MEMS technology (Micro-Electro-Mechanical Systems) and enable reliable detection of tilt and orientation relative to gravity. Thanks to their compact design, high measurement accuracy and fast response time, MEMS tilt sensors are ideal for a wide range of industrial applications.
At Althen, you will find a wide selection of MEMS inclinometers for precise tilt measurements in machines, vehicles and industrial systems. We offer analogue and digital inclinometers (tilt sensors) with capacitive MEMS technology. Each sensor can measure positive and negative tilt angles from +/-1° to +/-90° in single-axis and dual-axis configurations. By selecting the angle range, bandwidth, analogue or digital electrical output and other parameters, you receive exactly the sensor you need for your application.
How do MEMS inclinometers work?
MEMS inclinometers measure the tilt of an object relative to the Earth’s gravity using micromechanical structures inside the sensor. These structures respond to changes in acceleration, enabling precise determination of the tilt angle. This measurement principle gives MEMS inclinometers many advantages. They enable a compact design, fast signal processing and stable measurement performance, even in dynamic applications.
Advantages of MEMS inclinometers
MEMS inclinometers are often used when reliable and high-resolution tilt measurements are required.

Important selection criteria for MEMS inclinometers
When selecting a MEMS inclinometer for your application, several technical factors should be considered to ensure reliable tilt measurement and optimal integration into your system. Choosing the right sensor is essential for precise measurement data, stable signals and long-term operational reliability.
- Measuring range
First, the required tilt or angle measuring range of the application should be defined. MEMS inclinometers are available in various measuring ranges, such as ±30°, ±60° or ±90°. The selected sensor should be able to reliably capture the full tilt range in order to provide accurate measurement values across the complete range of motion. - Measurement accuracy and resolution
For many applications, tilt measurement accuracy is a decisive factor. Resolution, linearity and overall sensor accuracy should therefore be checked carefully. High resolution makes it possible to detect even the smallest tilt changes precisely. - Single-axis or dual-axis measurement
Depending on the application, a single-axis or dual-axis tilt sensor may be required. Single-axis inclinometers measure tilt along one axis, while dual-axis sensors can detect tilt changes in two directions simultaneously. - Output signal and interfaces
The sensor’s output signal also plays an important role in system integration. MEMS inclinometers are available with different signal types, such as analogue voltage or current signals, as well as digital interfaces such as CAN, RS485 or Modbus. The selected signal should be fully compatible with your control or data acquisition system. - Environmental conditions
The operating environment has a major influence on sensor selection. Factors such as temperature ranges, vibration, shock loads, humidity or dust can affect measurement performance. For industrial applications, inclinometers should be selected that are specifically designed for harsh environments. - Response time and dynamics
In applications with moving machines or vehicles, the sensor’s response time is also crucial. A MEMS inclinometer with fast signal processing enables precise detection of tilt changes in dynamic systems. - Mounting and installation
Mechanical integration should also be taken into account. The size, design and mounting options of the sensor must match the available installation space and enable stable installation to avoid measurement errors.
By carefully evaluating these factors, you can select the right MEMS inclinometer for your application. This ensures precise tilt measurements, reliable measurement signals and a long-term stable sensor solution for industrial and mobile applications.

Frequently asked questions about MEMS inclinometers
Answers to the most important technical questions
How do movement and acceleration affect MEMS inclinometer measurements?
MEMS inclinometers measure inclination relative to Earth’s gravity. In stationary or slowly moving applications, they provide very stable and accurate measurement values. However, additional accelerations caused by rapid movement, vibration, shock or changes in direction can affect the measurement signal.
This is because the sensor detects not only Earth’s gravity but also dynamic accelerations generated during movement. As a result, the measured inclination can temporarily deviate from the actual angle.
MEMS inclinometers are well suited to many industrial applications involving slow or controlled movement. For highly dynamic applications, Althen recommends selecting the sensor specifically for the application or, where necessary, using a combined sensor solution to measure inclination, movement and acceleration reliably.
How does Modbus communication work with MEMS inclinometers?
MEMS inclinometers with Modbus communication transmit measured inclination values digitally to a controller, data acquisition system or monitoring platform. The sensor measures inclination relative to Earth’s gravity and provides the measurement data via a digital connection such as RS485 with Modbus. Althen offers MEMS inclinometers with various output options, including analogue signals and digital communication options such as CAN, RS485 and Modbus.
In practice, Modbus usually operates according to the master-slave or client-server principle. A higher-level controller cyclically queries the inclinometer, and the sensor responds with the current measurement values, such as the inclination of the X and/or Y axis, status information or other device-specific data. Modbus RTU is commonly used over serial connections and is therefore well suited to industrial systems with multiple field devices. In this configuration, up to 20 sensors can be used in a shared bus system with time-coordinated addressing.
A key advantage is straightforward integration. MEMS inclinometers with Modbus can be integrated directly into automation, control and monitoring systems. Depending on the sensor model and application, parameters such as the measuring range, Modbus address, baud rate and data polling can be adapted to the existing system. The exact register assignment and communication parameters depend on the model and are specified in the relevant data sheet or technical documentation.
What is the response time of MEMS inclinometers?
The response time of MEMS inclinometers depends on the sensor model, selected filtering, bandwidth and output signal. In general, MEMS inclinometers are designed for fast signal processing and are also suitable for dynamic applications involving moving machines or vehicles.
For digital versions such as the JDI-100/200, the dynamic response can be configured. Depending on the setting, the data rate can be selected from 3.9 to 125 Hz, while the bandwidth is typically one quarter of the sampling rate. The filtering can also be adjusted by the user. For the JDHI, communication rates from 2,400 to 500,000 bps are selectable.
When selecting the appropriate model, the required response speed should be considered together with the measuring range, accuracy, vibration and installation conditions. Althen can help select a MEMS inclinometer with a suitable response time for the application.
Are MEMS inclinometers available with temperature compensation?
Yes. Althen offers MEMS inclinometers with temperature compensation. Depending on the model, temperature effects are digitally compensated to help keep inclination measurements stable and accurate under changing environmental conditions.
Examples include the JDI-100/200 MEMS inclinometer, which is digitally temperature-compensated, and the JDHI MEMS inclinometer. Both series are designed for industrial applications and operate over a wide temperature range from -40 °C to +85 °C.
Temperature compensation helps reduce measurement deviations caused by temperature drift. This is particularly important for outdoor applications, mobile machinery, automation, platform levelling and long-term monitoring. The most suitable version depends on the measuring range, number of axes, output signal and environmental conditions.
