1.发明申请GAS SENSING DRIFT COMPENSATION USING GAS SELF-REFERENCING FOR END OF SERVICE LIFE INDICATION FOR RESPIRATORS 有权使用燃气自动补偿的气体感测干燥补偿终止服务救生员生命指示公开(公告)号：US20140311211A1
公开(公告)日：2014-10-23
申请号：US13866770
申请日：2013-04-19
Applicant: HONEYWELL INTERNATIONAL INC.
Inventor： Christopher Scott Larsen , Peter Tobias , Andrew McIntosh
IPC: G01N15/08
CPC classification number: A62B9/006 , A62B18/088
Abstract: Embodiments relate generally to systems and methods for determining end of service life for a respirator cartridge by comparing the gas levels sensed at two or more sample points within the cartridge. Sample streams may run from the sample points to a gas sensor, wherein a valve may control the flow between the sample streams and the gas sensor.
Abstract translation: 实施例总体上涉及通过比较在盒内的两个或多个采样点处感测到的气体水平来确定呼吸器筒的使用寿命终止的系统和方法。 样品流可以从采样点运行到气体传感器，其中阀可以控制样品流和气体传感器之间的流动。
