Abstract
A probe suitable for monitoring temperature and pressure in a relatively thin-walled container fabricated from plastic. The internal probe monitors the pressure and temperature at substantially the geometric center of a container in a pasteurizing or sterilizing apparatus. The probe is provided with a sharp container-wall piercing end and a tapered threaded self tapping portion which provides an effective seal. The probe is hollow so that fluid can be conducted from the interior of the container and its pressure determined. A temperature sensing member is carried within the hollow probe so that temperature within the container may be sensed.
