Abstract: Generally, a sonde, associated components and methods are described which can be used in conjunction with an inground tool having an inground tool housing that defines an inground tool cavity such that the inground tool cavity is exposed to an ambient pressure environment which surrounds the inground tool during an inground operation. A sonde housing assembly includes an exterior configuration that is receivable within the inground tool cavity. The sonde housing assembly at least partially defines a sonde interior and is further configured for receiving the pressure sensor body of a pressure sensor in a pressure sealed engagement. A sonde electronics package is supported within the sonde interior and is at least configured to receive the pressure signal and transfer a corresponding pressure signal from the sonde.

Abstract: A device is described for use in performing an inground operation. An accelerometer is supported by the device for generating accelerometer readings that characterize the inground operation subject to a native temperature drift of the accelerometer. A set of compensation data is developed and stored for use in compensating for the native temperature drift. The compensation data is applied to the accelerometer readings to produce compensated accelerometer readings that externally compensate for the native temperature drift to yield an enhanced thermal performance which is improved as compared to a native thermal performance of the accelerometer. A seven position calibration method for a triaxial accelerometer is described. An air module is described which isolates the accelerometer of the device at least from a potting compound that at least fills otherwise unoccupied volumes of the device interior.
