With the combined vibration and temperature sensor CMSVT38, condition monitoring of machinery and equipment, as well as motors and pumps, can be achieved with a compact, energy-efficient, and easily integrable component. The CMSVT demonstrates its strengths particularly in the condition monitoring of electric motors, such as those used in conveyor systems.

In modern industrial applications, predictive maintenance of machines and systems is becoming increasingly important. Condition-monitoring sensors continuously capture critical condition parameters such as vibrations and temperatures, as well as other process and condition indicators. The data generated not only contributes to early fault detection but also plays an important role in automating previously manual, maintenance-intensive inspections. Moreover, they are an essential component of modern, connected manufacturing processes and support the transition to highly automated production.

The CMSVT38 from Kübler is a specially developed MEMS-based sensor that meets these requirements in a compact, energy-efficient, and easily integrable component, enhancing and completing systems effectively. The main application areas include machinery and plant engineering, manufacturers and operators of motors and pumps, as well as the process industry.

Technology And Functionality

The CMSVT38 is based on modern MEMS sensor technology and reliably measures vibrations in three axes as well as temperature values. The captured measurement data can be transmitted via the standardized IO-Link interface or displayed via a decentralized visualization tool, enabling intelligent analysis and monitoring of system conditions.

Alternatively, the sensor can be operated in SIO mode, where two PNP/NPN switching outputs can be individually parameterized and directly connected. This enables immediate visualization and reaction to defined threshold values even without complex control, for example via a signal light from Kübler.

Flexibility And Easy Integration

The IO-Link interface of the condition monitoring sensor ensures universal integration into various condition monitoring concepts and Ethernet networks—independent of control systems or fieldbus protocols. This saves time and costs in installation, parameterization, and maintenance.

Precise And Reliable Monitoring

With three-axis vibration measurement (X, Y, and Z axes) and temperature detection, the sensor provides detailed condition information that helps to detect machine damages such as contamination, misalignment, or imbalances caused by issues like bearing defects early on. The integrated capability for process step detection further supports quality assurance in production.

Typical Application Scenarios

The CMSVT demonstrates its strengths particularly in condition monitoring of electric motors, such as those used in conveyor systems. These motors often operate continuously and are subjected to mechanical stresses that can lead to bearing damage or imbalances. If such a defect is not detected early, costly downtime can occur. By directly mounting the sensor on the motor, vibrations in three axes as well as temperature values can be continuously recorded. The collected data is transmitted via IO-Link to the control system, where warnings can be issued or automatic shutdowns triggered if thresholds are exceeded. This increases system availability, enables planned maintenance, and minimizes the risk of failures.

Valuable Services in the Food Industry

Even in building technology or the food industry, such as when using fans in cold storage facilities, the condition monitoring sensor provides valuable services. A failure of these components can have severe effects on temperature stability and thus product quality. The sensor monitors both the vibration of the fan shaft and the contact temperature. In the event of imbalances or bearing damage, the sensor detects anomalies early and issues predefined switching signals in SIO mode, which can, for example, activate signal lights like the SL55. These provide immediate visual feedback—green in normal operation, yellow or red when defined thresholds are exceeded. At the same time, backup fans can be automatically activated to maintain smooth operation.

These examples clearly demonstrate how versatile the CMSVT38 sensor can be used in industrial everyday life—for increasing efficiency, ensuring processes, and reducing unplanned downtime.
