ASC develops ASC AiSys
14/01/2022
ASC in Germany has developed the ASC AiSys® VibroTherm smart sensor system together with EPHY-MESS, a manufacturer of temperature sensors. The new sensor solution brings together the expertise of both measuring technology specialists in a single product that offers new capabilities in condition monitoring. Combining the vibration and temperature measurement allows for the early detection of changes in bearing or gear behaviour.Damage is detected in the initial stage, making it possible to prevent costly repairs.
Measurement of two completely different variables, such as temperature and vibration, using a single sensor unit was possible only with custom solutions in the past. The ASC AiSys VibroTherm smart sensor system offers this functionality as a standard feature in a compact design. The major advantage of the sensor system is the synchronous measurement of temperature and vibrations; a temperature sensor alone, for example, would not be sufficient to provide early warning of bearing or gear wear. It only reacts if the temperature significantly exceeds a threshold value. By this time, however, major damage has already occurred. This is why the ASC AiSys VibroTherm smart sensor system also measures accelerations, on the basis of which vibrations and oscillations can then be calculated.
The accelerometer of the sensor unit features scanning rates of up to 4 kHz per axis, the temperature sensor up to 50 Hz. The sensor system operates with a 20-bit resolution for measuring acceleration and a 15-bit resolution for measuring temperature. The ASC AiSys VibroTherm smart sensor system features measuring ranges between ±2 g and ±40 g for the acceleration measurement and between –40°C and +125°C for the temperature measurement.
The simplified circuitry of the ASC AiSys VibroTherm significantly reduces engineering expenses. Since the sensor system also analyses the measurements independently, this eliminates the need for external data processing.
