Abstract: A system is provided that includes an input node configured to receive a signal indicative of sensor data. The system also includes a first transistor configured to route the signal to a positive channel when a polarity of the signal is positive. Moreover, the system includes a second transistor configured to route the signal to a negative channel when a polarity of the signal is negative. Additionally, the system includes the positive channel coupled to the first transistor configured to route the signal to an analysis component. Furthermore, the system includes the negative channel coupled to the second transistor and configured to route the signal to the analysis component.

Abstract: Embodiments of the invention described herein provide a magnetic sensor interface capable of adjusting signal conditioning dynamically using a speed signal of a target such that the true positive and negative peaks of the input signal are maintained for the given target across its entire speed range (0-Max rpm), therefore increasing the signal to noise ratio at low speeds and avoiding clipping or distortion at high speeds. In one aspect, a method comprises receiving an alternating differential voltage signal from a sensor. The differential voltage signal has an amplitude that changes relative to a change in speed of a target. The alternating differential voltage signal is converted to an attenuated single-ended voltage signal that can be dynamically scaled. The attenuated single-ended voltage signal can be scaled by multiplying the attenuated single-ended voltage signal by a scaling factor.

In one aspect, a method comprises receiving an alternating differential voltage signal from a sensor. The alternating differential voltage signal has an amplitude that changes over time. The alternating differential voltage signal is converted to an attenuated single-ended voltage signal that can be dynamically scaled. The attenuated single-ended voltage signal can be scaled by multiplying the attenuated single-ended voltage signal by a scaling factor. The scaling factor is selected relative to a signal-to-noise ratio of the scaled attenuated single-ended voltage signal.

Abstract: A monitoring system for use in monitoring operation of a rotating device includes a first monitor including a first processor. The first monitor is configured to receive a phase reference signal from a rotation sensor, wherein the phase reference signal is indicative of a phase of rotation of the rotating device, generate a timestamp indicative of a time at which the phase reference signal was received, and generate a synchronization message including the timestamp and an indication that the phase reference signal was received. The monitoring system also includes a second monitor operatively coupled to the first monitor and comprising a second processor. The second monitor is configured to receive the synchronization message from the first monitor and synchronously sample at least one measurement based on the synchronization message.
