A system including a sensor housing including a channel, and cantilever beam connected to the sensor housing and disposed within the channel. The system also includes an actuator connected to the cantilever beam and configured to cause the cantilever beam to vibrate. A sensor is connected to the cantilever beam and is configured to generate a first signal representing a cantilever beam vibration of the cantilever beam. The system also includes an accelerometer connected to at least one of the sensor and the sensor housing, the accelerometer configured to generate a second signal representing an external vibration of the sensor housing. The external vibration changes the cantilever beam vibration. The system also includes a signal processor configured to receive, as input, the first signal and the second signal and to generate, as output, a filtered signal that reduces an effect of the external vibration on the cantilever beam vibration.

Fluid density and viscosity measurement tool with noise cancellation

A sensor package may include a sensor housing unit and a first sensor that may acquire a first set of measurements within a first measurement range. The sensor package may also include a second sensor configured to acquire a second set of measurements within a second measurement range. The first measurement range and the second measurement range may include an overlapping range used to calibrate the first set of measurements, the second set of measurements, or both.

Systems and methods for enhancing data acquisition operations in seismic surveys

A detection system includes a pressure sensor configured to contact an annular elastomer component of an annular BOP, wherein the pressure sensor is configured to generate a first signal indicative of a contact pressure with the annular elastomer component. The detection system also includes a piston stroke sensor configured to generate a second signal indicative of a piston stroke distance. The detection system further includes a controller configured to receive the first signal from the pressure sensor and the second signal from the piston stroke sensor and analyze respective changes in the contact pressure and respective changes in the piston stroke distance to determine a condition of the annular BOP.

Detection systems and methods for an elastomer component

A sensor system includes interconnected and axially spaced apart sensor devices deployed along an outer surface of a downhole tool string. The sensor devices including a sensor disposed with a protective housing and control electronics located remote from the sensor devices and operationally connected to the sensors.
