Patent ID: 8433485

Claim:
An assembly comprising: a first member having an inner surface that defines a bore along an axis, wherein the first member has a first fluid port that communicates a fluid to the bore and a second fluid port that communicates the fluid from the bore, wherein the first fluid port is located a distance along the axis from the second fluid port; a receiver located within the bore, the receiver having an electronics package and an outer surface sealingly engaged with the inner surface of the first member, the outer surface defining a fluid channel parallel to the axis and in communication with the first fluid port and the second fluid port; a second member disposed through the receiver; and a transmitter coupled to the second member, wherein the fluid communicates from the first fluid port through the fluid channel to the second fluid port, and wherein a current is supplied to the electronics package of the receiver thereby magnetizing the transmitter, and wherein as stress due to torque is applied to the second member and therefore the transmitter the electronics package of the receiver detects a magnetic field from the transmitter that is proportional to the torque applied to the second member.
