Condition monitoring

Conditonal monitoring applies to various industries such as energy, automotive, construction and many more requiring to boost their productivity levels and decrease production and maintenance costs. With the expansion of advanced technologies in the modern era, industries have become more keen in developing sustainable technologies that utilize conditional monitoring.

Conditional monitoring helps in assessing the quality of a product during the production process itself and control key factors affecting the results such as temperature, vibration, contamination and other factors. These factors are controlled and improved in order to ensure safety, decreased environmental risks and optimised plant efficiency.

Monitoring the commutator in electric motors

For electric motors located in difficult-to-reach places, continous monitoring of commutator condition is advisable. The commutator monitoring practices are employed in research and development laboratories, for quality control during and following production, or during commissioning of plant.  For performing these monitoring tasks, eddy current sensors are incorporated to monitor the mechanical condition of the commutator in DC electric motors or generators. The eddyNCDT measuring system includes a sensor, an interconnecting cable and a signal conditioning electronics. The eddy current sensors are not subject to wear and cannot influence the commutator.  The possible applications of eddy current sensors in the monitoring of electric motor are...


Vibration displacement measurement in road tests

The automotive industry requires the testing a chassis or the base frame of the vehicle for ensuring driving safety of a vehicle. For doing this, highly robust sensor technology is required that can also withstand the high demands of road tests. Draw-wire sensors are considered suitable for performing this type of measurement for they are available in miniature size, are easy to fit and use and highly economical. The draw wire sensors are mounted parallelly to the shock absorbers for measuring the vibration displacement and the data is recorded for varying road surface quality. The resultant displacement signal is then differentiated to...


Measuring vibrations on an engine manifold

An internal combustion engine demands continuos optimization of processes. For this, a whole series of engine management operations are required. This includes temperature measurement of the exhaust gas that is done using a thermocouple within the manifold and examining the propensity to vibrate in the comubustion engine. It is also important to examine the way the combustion engine is attached  and the mechanical rigidity of the structure. To perform this kind of measurement, blue laser sensors are incorporated. The high-temperatures in the flow of exhaust gas leads to the thermcouple self-fluorescing, due to which short wavelength of the blue-violet laser provides decisive advantage....


Brake disc topography measurement

In the automotive industry, brake disc testing is carried out in order to check the wear of the brake pads. They can be made from a variety of materials such as grey cast iron or ceramics.  If a brake disc has been made with ceramics, it is more likely to exhibit great response characteristics, braking power and component weight reduction. To measure any wear in the brake pads, several tests are conducted. The major challenge faced during these tests is the changing surface structure such as matt, glossy, rough or smooth. Laser traingulation sensors are used in this process to detect wear of the...


Load detection in washing machines

Load measurement in washing machines is required to lower operating costs and environmental damage. The load must be measured before the washing starts to determine the appropriate dosage of detergent required to wash a certain amount of clothes. A cost-effective and efficient way to do this is by using magneto-inductive displacement sensors. These sensors are directly integrated into the damper. The sensors are capable of detecting the position of the piston in the damper continuously and with high dynamics. The sensor has a highly compact structure and a measuring range of 40mm and above. On loading the washing machine, the...
