A CONDITION MONITORING DEVICE AND A SYSTEM FOR THE CONDITION MONITORING OF INDUSTRIAL MACHINERY

摘要

The subject of the invention is a condition monitoring device (1) and a system (101) for condition monitoring of industrial machinery applies in a diagnostic matter in industry. A device according to the invention comprises an enclosure (17) where an electronic system (2) with at least one sensor (11a) for measurement of physical quantities of the industrial machinery (20) is placed and the electronic system (2) is connected wirelessly with an external portable device (60). The system (2) comprises a sensor module (11) which is adapted for receiving and recording an analog signal from the sensor (11a); an analog/digital converter module (12), for converting an analog signal output into a digital signal; a processing module (13) for processing the digital signal and the processing module (13) is adapted for analysing a sensor data to determine an operating condition of the machinery by using a diagnostic algorithms implemented in the processing module (13); a memory module (14) for storing the signal outputs; a communication module (15) for wirelessly communicating the processed signal outputs or for communicating the raw, unprocessed data directly from the sensor module (11); an energy module (16) having an electrical connection with each of the modules (11,12,13,14,15) for energizing them during the operation time of the condition monitoring device (1). The all modules (11, 12, 13, 14, 15, 16) of the electronic system (2) are situated inside the rigid enclosure (17), which enclosure (17) is detachably fix to the industrial machinery (20) as a corresponding part of the industrial machinery (20) in such a way that the system (2) is placed entirely inside the body of the industrial machinery (20) or the enclosure (17) is an integral part of the industrial machinery (20).
