Abstract: An improved temperature measuring device for the in-line temperature measurement of fluids which does not require intimate contact of the fluid with the temperature sensing element. In addition, the invention contains no internal cavities or crevices making it very advantageous for food and chemical usage. In the preferred embodiment, a liquid crystal temperature sensing element is affixed to a thermally conductive fluid carrying member. Each end of this fluid carrying member having fittings which enables the thermometer assembly to be quickly removed for cleaning and sanitizing.

Abstract: A recuperator core has a plurality of passages sealingly formed therein. In use, a fluid passes through a respective one of the plurality of passages under pressure. The recuperator core must be tested to determine an operational efficiency or leakage within the respective plurality of passages. A pair of sealing mechanisms are positioned at a respective one a pair of ends of the respective one of the plurality of passages. A pressure or a vacuum is pulled across the respective ones of plurality of passages and a rate of leakage or decay rate is monitored to define an operational recuperator core and a failed recuperator core.
