Ideally, rolling bearing elements are separated by a protective lubricant film, which impedes their collision. However, manufacturing defects, damages, which appear during operation, dirt in the bearing, insufficient or incorrect lubrication – all these factors cause the collision of the bearing elements and, as a result, acoustic oscillations of a wide spectrum are generated in the bearing body. Standard Conditions for Operation: - Operating temperature (device & sensor), -10 to 55°С, (±5)°С; - Relative humidity 80% at temperature 30 °С; - Atmospheric pressure, 84 to 106.7 KPa (630 - 800 mm Hg); - Resonance frequency, 32 kHz; - Measurement unit, dBi, dBc, dBm; - Range, max. 99dB; - Resolution, 1 dB; - Accuracy, ± 5%; - Operating temperature (tacho), 10 to 55°С, (±5)°С; - Tachometer range, 50-30,000rpm; - Tachometer resolution, 1rpm; - Tachometer sensing distance, up to 1m; - Memory capacity, 2MB; - PC communication port, USB;
