Abstract: A hand-held thermography system (8). A generator (10) supplies current to a transformer (15) in a handle (16). An induction coil (20) connected to the transformer (15) extends from the handle (16). The induction coil (20) induces eddy currents in a test object (50), producing a thermal topography on a surface (52) of the object (50) that reveals structural features including defects in the object. An infrared camera (24) mounted on the transformer (16) digitizes images of the thermal topography.

Digitized positional data relating the position of the image to the surface may also be stored. An operator (40) presses a trigger (17), signaling the controller (12) to start current to the induction coil (20) and simultaneously to acquire and process one or more images from the camera (24).

Abstract: A temperature sensor located at a region being monitored controls an output switch that in one position when ambient temperature is below a predetermined temperature applies current to only a first loop circuit and in another position when ambient temperature is at or above the predetermined temperature applies current to only a second loop circuit. Currents in the first and second loop circuits are measured by ferrods to determine whether an over-temperature condition at the region monitored has taken place. An alarm circuit connected to outputs of the ferrods generates an alarm signal in response to a negative transaction of current in the first loop circuit or a positive transition of current in the second loop circuit. A failure in either loop circuit accordingly is insufficient to disable the system. A solid state timer periodically opens the second loop circuit to repeat the alarm signal when the second loop circuit is closed until corrective action is taken.

Abstract: A grain temperature monitor for use with one or more grain bins, the monitor including one or more temperature sensors, an analog sensor indicator unit, and a non-analog sensor indicator unit. The analog sensor indicator unit provides a signal when one or more of the temperature sensors senses a temperature in the monitored grain that equals or exceeds a predetermined reference temperature. In addition, an operator controllable switch can be manipulated to determine the approximate temperature of the highest sensed temperature. The non-analog sensor indicator unit provides a visual indication as to which of the temperature sensors then currently senses the highest temperature, without regard as to whether such sensed temperature exceeds the predetermined temperature threshold or not.

Abstract: A temperature increase or excursion sensor and locator consisting of a temperature sensitive cable which includes three electrical conductors, two conductors are separated by a dielectric member to form a linear strip capacitor and one of the two conductors has a number of thermostatic devices connected serially. Over or under temperature excursions are sensed and located by the cable when it is connected to control electronics by detecting the continuity and by measuring the capacitance of the cable. Under normal conditions, all of the thermostatic devices are electrically conducting and the control electronics measures the full capacitance from both ends of the cable and detects continuity over the full length of the cable. Upon a temperature increase or an excursion, one or more thermostatic devices become non-conductive, creating a discontinuity in one of the conductors and in addition the resulting capacitance is proportionately reduced.

Abstract: A temperature monitoring and display system is used in conjunction with two or more low temperature sensors which produce output currents representative of the temperature being sensed. The currents produced are converted to voltages and applied through differential amplifier circuits to produce output analog signals representative of the sensed temperatures. These signals also are applied to a differential comparator which produces an output signal having a sign and magnitude representative of the difference in the sensed temperatures. A switch is used to select any one of the outputs of the first and second differential amplifiers or the comparator and to apply this output signal to an analog-to-digital converter, the outputs of which then are used to drive a suitable digital display.
