Abstract
Described herein are methods and systems for configuring sensors to compensate for a temperature gradient. Multiple sensor sets, each having at least two sensors of a same type with orthogonal axes, are positioned to form at least one opposing sensor pair, in which an axis of one sensor of one sensor set is in an opposite orientation to an axis of one sensor of another sensor set. A combined measurement of each opposing sensor pair may be output which is compensated for an effect of a temperature gradient on sensor measurements of the sensors

A method for configuring sensor sets to compensate for a temperature gradient, comprising:
- providing a first sensor set, having at least two sensors of a same type that have axes orthogonal with respect to each other;
- providing a second sensor set, having at least two sensors of the same type that have axes orthogonal with respect to each other;
- positioning the first and second sensor sets with respect to each other to form at least one opposing sensor pair, in which an axis of one sensor of one sensor set is in an opposite orientation to an axis of one sensor of another sensor set;
- outputting a combined measurement of each opposing sensor pair, wherein each combined measurement is compensated for an effect of a temperature gradient on sensor measurements of the sensors.
A sensor configuration to compensate for a temperature gradient, comprising:
- a first sensor set, having at least two sensors of a same type that have axes orthogonal with respect to each other;
- and
- a second sensor set, having at least two sensors of the same type that have axes orthogonal with respect to each other,
- wherein the first and second sensor sets are positioned with respect to each other to form at least one opposing sensor pair, in which an axis of one sensor of one sensor set is in an opposite orientation to an axis of one sensor of another sensor set and wherein the sensor configuration is operable to output a combined measurement of each opposing sensor pair, wherein each combined measurement is compensated for an effect of a temperature gradient on sensor measurements of the sensors.
A sensor set to compensate for a temperature gradient, comprising a first sensor set, having at least one sensor having an axis, and a packaging that allows direct and inverted mounting, wherein mounting one sensor set with direct mounting and one sensor set with inverted mounting forms at least one opposing sensor pair, in which the axis of the at least one sensor of one sensor set is in an opposite orientation to the axis of the at least one sensor of the other sensor set so that measurements from both sensor sets are combinable to compensate for an effect of a temperature gradient on sensor measurements of the sensors.
