Problems solved by technology

In such cases, the extra space required to place the external filter poses a major problem
On the other hand, placing the filter inside the measuring device creates the problem that the user of the instrument cannot change the filter when required, with the result that the measuring device has to be taken out of service for maintenance to replace the filter

Abstract

A replaceable filter integrated into a front panel fitting interconnect system of a gas sampling system, the replaceable filter includes a filter body mounted within a housing of the system. The filter body is insertable into the filter receptacle and is removable from the filter receptacle by a twist lock mechanism. Filter body includes integral accessory socket. The accessory connector is pluggably connectable to the accessory receptacle.

Description

technical field [0001] The inventive concepts described herein generally relate to replaceable filters for gas sampling systems. More particularly, the present inventive concept relates to replaceable filters insertable into a filter receptacle and including an integrated accessory receptacle for removable connection with an accessory connector. Background technique [0002] Gas detection and measurement systems typically collect gas samples through tubes or a continuous flow of gas from the desired sampling location, and the samples are then provided to a measurement device for analysis. In many applications such as respiratory gas monitoring, water and other contaminants may be present in the gas being collected and monitored. Various types of filters and water removal devices are often utilized at one or more points along the sampling line to prevent such contaminants from being introduced into the interior of the measurement device, thereby preventing contamination from...
