Central Condition Monitoring of Motors

Reliable condition monitoring using the QM42VT1 vibration and temperature sensor

Whether in exhaust systems, pumps or compressors – motors of various sizes are used in production plants and warehouses, quite often in remote locations. Maintaining machines is therefore time-consuming and prone to errors, especially if maintenance personnel are only instructed to perform on-site inspections on an infrequent basis. 

Instead, data from multiple motors can be collected, evaluated, centrally displayed and, if necessary, linked to alarm actions in order to warn of impending failures in good time. Users can use radio technology to connect the QM42VT1 vibration and temperature sensor with the high-performance TX700 HMI device for this purpose.

Your Benefits

  • Easy retrofitting of the control system without intervention in the control system
  • Reliable motor operation through monitoring with individual data visualization and automatic alarms 
  • Targeted assignment of technical personnel thanks to efficient, predictive maintenance
  • Access to data of motors with limited accessibility

  • Mounted directly on the motor, the QM42 sensor detects vibration and temperature values

  • Wireless: The status data is sent via a proprietary wireless network

  • The TX700 visualizes measured data and alarms

Rugged Sensor Detects Vibration and Temperature Values

Has the motor become loose, causing the shaft to be misaligned? Is a bearing jammed or is an attachment out of balance? Mechanical vibration can flag up issues such as these. The QM42VT1 vibration and temperature sensor detects vibrations with a high level of accuracy. For this purpose, the compact MEMS-based sensor (Micro-Electro-Mechanical System) is simply mounted directly on the motor block via a magnetic holder. From there, it delivers speed and acceleration data over two dimensions in different frequency ranges. Changes in the measurement data can then be used to identify various forms of damage.

Measuring the temperature of the motors is also vital, as a significant increase in temperature could be an indication of wear or insufficient lubrication on a bearing. The IP67 sensor also detects such temperature changes within a measuring range of -40 °C to +105 °C.

Data Transfer via a Proprietary Wireless Network

Maintenance personnel can wire the vibration and temperature sensor to the battery-powered DX80 radio module. The measured values are then sent to the receiver module of the DX80 system via a proprietary wireless network. 

Customized Data Visualization

Maintenance personnel see all engine status data clearly displayed on Turck's HMI/PLC TX700. Thanks to the TX VisuPro software, the values from the motor can be displayed in a variable manner. In addition, users can read out historical trends, extract log data or configure alarms such as automatic e-mail notifications. Ethernet connection to the company network is also possible, allowing data to be queried throughout the entire company.

Control System as a Stand-Alone Solution

With this stand-alone solution, maintenance personnel can always view the status data of all machines – whether on site at the HMI or on every computer in the company network.
