Orientation device for a gas analyzer
First Claim
Patent Images
1. A gas analyzer having an orientating system comprising:
- a housing having an inlet and outlet for exchanging a sample of gas;
a sensor located within the housing that senses at least one characteristic of the sample of gas;
a pump to circulate the sample of gas to said sensor and to said outlet;
a purge solenoid connected to said pump and to said outlet;
and an orientation determiner that determines the orientation of the analyzer;
wherein the gas analyzer is a handheld analyzer;
wherein the orientation determiner determines the orientation of the gas analyzer with respect to an axis that can be selected from a group consisting of x-axis, y-axis, z-axis, other axis, or a combination thereof; and
wherein the purge solenoid operates to purge the analyzer of contaminant when the analyzer is in a certain orientation based on the orientation determined by the orientation determiner.

Abstract
A method and apparatus for determining the orientation of a gas analyzer. Because condensation can build-up in a filter of the gas analyzer, it needs to be purged from the analyzer so that accurate readings can be made. By having a orientation device built-in, the analyzer can be purged at the desired orientation so that, as much water, can be purged, as possible, to the designated outlet.
