ABSTRACT:
A temperature indicating device for use with a conduit system wherein a fluid material is moved and is weighed by a continuous weighing mechanism comprising (a) an adapter which is partially shaped to be detachably connected to said continuous weighing mechanism and incorporated into said conduit system on that portion of said continuous weighing mechanism where the fluid material passes therefrom, said adapter being provided with a nipple in the side wall thereof; (b) a sensing probe which is slideably mounted within said nipple, said sensing probe extending throughout the entire length of said nipple and into the interior portion of said adapter whereby the sensing probe will be in thermoconducting relation with the fluid material moving through said adapter; (c) a control module containing input and output circuits, disposed remotely from said sensing probe and interconnected therewith by suitable electrically conductive means, said control module adapted to receive a signal from said sensing probe via said input circuit and upon preset circuity conditions, energize an outside electrical power supply such as alternating current lines through said output circuit.
