A condition monitoring device configured to be mounted on a machine for sensing, for example, vibrations produced by the machine during operation, includes a base, a printed circuit board assembly lying in a first plane, and first and second fasteners, each having a longitudinal axis, lying in a second plane perpendicular to the first plane, the first and second fasteners extending through the printed circuit board assembly and into the base. A third plane is perpendicular to the first and second planes and is located halfway between the longitudinal axes of the first and second fasteners. An integrated power supply is connected to the printed circuit board assembly, and at least two active sensing cells, such as vibration sensors, are arranged symmetrically relative to the second plane and/or symmetrically relative to the third plane.

Wireless machine condition monitoring device

An analog output current transmitter includes a first circuit portion that generates analog sine and cosine voltage signals, a second circuit portion that transforms the analog sine and cosine voltage signals into current signals, the signals being transformed by an operational transconductance amplifier, and a third circuit portion providing a current limiter, the current limiter circuitry limits the output current to a defined threshold. No microcontroller is required in order to monitor and regulate the output current to the defined threshold. Also a system and method for sensing shaft bearing shaft rotation over 360 mechanical degrees having an analog output current transmitter is provided.
