WIRELESS BEARING MONITORING DEVICE

摘要

The invention relates to a bearing monitoring device including a sensor assembly (20) configured be mounted on a cover member (18) of a bearing and a wireless transmitter for transmitting and receiving data relating to the operation of the sensor assembly (20) in a predetermined frequency range, wherein the wireless transmitter includes at least one antenna (22). In order to account for detuning due to lubricant and steel in the environment of the antenna (22), the antenna (22) has a rated frequency range, wherein a lower limit frequency of the rated frequency range is higher than an upper limit frequency of the predetermined frequency range.
