Mechanical maintenance

Repairing mechanical components should always only be considered as a last resort. This is because those responsible for smooth operation and for maintaining mechanical production plants naturally wish to avoid downtimes and malfunctions as far as possible. Innovative thermal imagers from Testo assist with the detection and analysis of thermal anomalies.

Non-contact and carried out during operation

Signs of wear in machinery often become apparent long before a malfunction, due to an increase in temperature. Possible causes are friction, incorrect adjustment, tolerances of mechanical components or a lack of lubricant. With a thermal imager, any suspicious changes can be spotted immediately. The main advantage of infrared measurement in a maintenance operation: it is non-contact and can therefore be carried out on all mechanical installations during operation and from a safe distance.

The level control in sealed fluid tanks has proved to be a sensible method for avoiding machine damage and as a result production losses.

Non-contact fill level check with a thermal imager

Non-contact thermographic measurement will allow you to check whether an oil separator is full, for example, in practically no time at all. Dangerous overheating in coolant tanks can be prevented: if the fluid contained in them falls to a dangerously low level, machines are no longer being sufficiently cooled. An automatic fill level monitoring device often regulates the level of the refrigerant and triggers an alarm if the fill level is too low. However, the automatic monitoring system can also fail. With this in mind, it will also pay you to take a regular look using a thermal imager from Testo. Monitoring using thermography ensures that systems operate safely.
 

High process temperatures require regular thermographic inspection of the system's insulation with respect to damage that may occur over time, e.g. due to material fatigue or wear. This includes, for example, using thermography to examine industrial furnaces and ladles for defects, material fatigue and coking.

Using the thermal imager's high-temperature measurement means that the system can be checked quickly and non-contact, from a safe distance.

In thermographic quality assurance or process optimisation, the temperature distribution of the product to be manufactured is checked as a matter of priority. Conclusions are drawn as to whether the requisite target process temperature has been uniformly attained. This enables us to ascertain whether the quality of the final product will prove satisfactory.

The main advantage of thermography: this high-temperature measurement can be carried out while the process is ongoing.
