Abstract: A sensor insert for positioning a temperature sensor within a glycol bottle. The sensor insert may be transparent and in the general shape of a tube, and is adapted for insertion in a bottle having an upper opening and a bottom. The sensor insert can also comprise an insert body having a first end, a second end and an inner surface. The insert body may be tapered from the first end toward the second end, for easy insertion into the bottle. The sensor insert can hold a temperature sensor away from the bottom and sides of the bottle to enable more accurate temperature readings. The insert also allows fluid within the bottle to be in contact with the temperature sensor due to fluid openings in the insert body.

Abstract: A sensor housing assembly for enclosing an electrical interface circuit, a sensor or sensor input, and a connector for interfacing with a data unit. The sensor housing assembly generally includes a housing containing a circuit board and interface circuitry to condition a sensor input signal, and a connector mounted on the circuit board, the assembly being insertable into a data unit. The housing can include a protrusion that prevents the assembly from being inserted into the data unit incorrectly, which also allows a symmetrical connector to be used. The sensor housing assembly is adapted to be inserted into a receptacle in the data unit, which has blocking tabs that act with the protrusion to ensure that the assembly can only be inserted one way.

Abstract: A method and apparatus for supporting and orienting a workpiece and a workpiece for use therewith. In one form, the apparatus for supporting and orienting the workpiece includes a body having first and second mating structures for connecting the apparatus to a data recorder and connecting the workpiece to the apparatus, respectively, and an indexing mechanism for orienting the workpiece so that it may be connected to the apparatus in no more than one orientation per side. The workpiece for use therewith further includes first and second openings which correspond to the second mating structure and indexing mechanism so that the workpiece may be connected to the apparatus in no more than one orientation per side. The apparatus and workpiece further provide methods for supporting and orienting the workpiece so that the workpiece may be connected to the apparatus in no more than one orientation per side.
