Abstract
A sensor includes a vapor sensitive medium and a means for monitoring at least one property of the vapor sensitive medium. The vapor sensitive medium is chosen such that it exhibits a response to the vapors absorbed by an absorbent bed which is substantially the same as the response of the absorbent to the vapors absorbed. The monitored property is a function of the response of the vapor sensitive medium to the vapors absorbed. Also disclosed are an absorbent bed alarm system employing the sensor and a filter cartridge which employs the adsorbent bed alarm system.
