Abstract: Disclosed example pressure transducers include: a pressure housing comprising a first cavity; a fluid input line configured to provide a fluid to the first cavity; a first pressure measurement assembly having a first type and configured to output a first measurement signal based on a pressure of the fluid in the first cavity; a second pressure measurement assembly having a second type and configured to output a second measurement signal based on the pressure of the fluid in the first cavity; and a controller configured to determine the pressure of the fluid in the first cavity based on the first measurement signal when the pressure is within a first range and determine the pressure of the fluid in the first cavity based on the second measurement signal when the pressure is within a second range.

Abstract: Disclosed example pressure transducers include: a housing; a fluid inlet configured to provide a fluid to a first cavity within the housing; a pressure measurement assembly comprising a microelectromechanical pressure sensor configured to output a signal representative of the pressure in the first cavity; and a heater configured to heat the pressure measurement assembly based on a target temperature.

Abstract: Bits configured for drilling rock that are of the type that includes a plurality of teeth supported in pockets that are on a cutting face that is driven to rotate. The pockets are configured to allow the teeth to passively rotate while in the pockets. The present disclosure provides a bit having hardfacing around the pockets and related methods.
