In one implementation, a circuit can include a reference pin and an operational amplifier that can include an output pin, an inverting input pin and a non-inverting input pin. The inverting input pin can be electrically coupled to the output pin via a first impedance and to the reference pin via a second impedance. The non-inverting input pin can be electrically coupled to the reference pin via a third impedance and can be configured to receive a detection signal. The reference pin can be configured to receive a detection reference signal associated with the detection signal.

Differential noise cancellation

A method includes receiving data characterizing an output of a sensor coupled to an industrial equipment. The output can include a sum of a first secondary coil and a voltage of a second secondary coil. The first secondary coil can be included in a first circuit and the second secondary coil can be included in second circuit configured within the sensor. The method can also include determining an integrity state of a circuit configured within the sensor. The integrity state can be determined based on the received data. The integrity state can identify a state of operation of the circuit configured within the sensor. The method can further include providing the integrity state. Related systems, techniques, and non-transitory computer readable mediums are also described.

Sensor circuit diagnosis

A flexible monitoring system and corresponding methods of use are provided. The system can include a base containing backplane, and one or more circuits communicatively coupled to the backplane. The circuits can be designed with a common architecture that is programmable to perform different predetermined functions, such as input, output, and processing. By separating functions of the flexible monitoring system into different circuits, new implementations of the flexible monitoring system can be rapidly developed by arranging already created components in different combinations. Multiple bases can also be communicatively coupled in a manner that establishes a common backplane between respective bases. Accordingly, implementations of the flexible monitoring system distribute combinations of circuits across different bases, providing flexible deployment options.

Flexible and scalable monitoring systems for industrial machines

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.

Automatic bipolar signal switching

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. The scaling factor is selected relative to the speed signal and is selected relative to a signal-to-noise ratio of the scaled attenuated single-ended voltage signal.

A printed wiring board (PWB) including one or more embedded capacitors. The PWB defines a planar area and includes a plurality of first conductive plates that are substantially parallel to the planar area and extend from a first normal axis towards a second normal axis. The first normal axis and the second normal axis extend substantially perpendicularly through the planar area.
