Gas detection management system with replacement modules

摘要

A calibration system is provided that supports a plurality of multi-gas detectors and that includes additional options for delivering additional test gases to the detectors. The system can include a calibration module for calibrating a multi-gas detector with a first gas and a replacement module capable of being coupled to the calibration module. When coupled to the calibration module, the replacement module can support delivering a plurality of test gases, not including the first test gas, to the calibration module.

1. A system comprising:
at least one calibration module for calibrating a multi-gas detector; and an expansion module capable of being inserted into an outlet of the calibration module, wherein the calibration module includes:
a first solenoid,a main delivery line coupled to the first solenoid,a plurality of test gas inlets coupled to respective ones of a first plurality of test gas lines terminating at a first side of the outlet, anda plurality of test gas outlets coupled to respective ones of a second plurality of test gas lines terminating at a second side of the outlet, wherein the expansion module includes:
a plurality of solenoids coupled to each other,an expansion delivery line coupled to one of the plurality of solenoids, anda plurality of gas expansion lines coupled to respective ones of the plurality of solenoids, wherein, when the expansion module is inserted into the outlet of the calibration module, the expansion delivery line couples to the main delivery line, and wherein, when the expansion module is inserted into the outlet of the calibration module, the plurality of gas expansion lines couples to respective ones of the first plurality of test gas lines and to respective ones of the second plurality of test gas lines so that gas in each of the first plurality of test gas lines flows to a respective one of the plurality of solenoids, via a respective one of the plurality of gas expansion lines.
