Abstract: A monitoring (10) device is provided for use in association with a limit switch or similar mechanically actuated device (16) in order to permit its end of life to be predicted. The system uses nonvolatile random access memory (18) to store a count which represents the number of occurrences of one of two alternative events. The first event is the occurrence of a number of switch actuations and the second event is the lapse of a predetermined period of time. When either of these two events occurs, a microprocessor increments a count in the nonvolatile memory unit and clears both the clock (12) and the volatile memory parameter. When the number stored in the nonvolatile memory represents a number of actuations estimated to be appropriately equal to the total life of the switch, this condition can be signaled to a sensor bus by a communication circuit (22). Alternatively, a light emitting diode can be alternately energized and de-energized to represent the number of actuations having exceeded the predicted end of life total.

Abstract: A high pressure proximity sensor for high pressure environments uses a balanced bridge variable inductance magnetic core structure to detect the presence of a external ferrous object by a change in inductance. The sensor magnetic flux path is defined by the sensor's specific geometry which includes core windings (20, 22) on the core and sensor housing (2). The core includes centre post (26) of a nonmagnetic material to transfer stress from a housing sensor face to the core's symmetric axis to cancel the effect of an external pressure induced stress on the sensor. The centre post (26) is encircled by an elastomer barrier (28) between the housing sensor face and an adjacent end of the internal core to prevent migration of an internal potting compound between the core end and the sensor face. This structure provides satisfactory sensor operation in environments imposing shock and vibration on the sensor as well as high external pressures.

Abstract: A colorimeter (5) for characterising the colour of an object is placed in an environmentally sealed enclosure (10) for use in industrial environments. In order to maintain an acceptable operating temperature for the colorimeter's electronics and lamp, a heat shield (220) is placed around the lamp to substantially isolate it from the electronics. The heat shield and the environmentally sealed enclosure are made of a highly heat conductive material such as aluminum. The heat shield is thermally coupled to the environmentally sealed enclosure.

Abstract: A colorimeter provides compensation for changes in the color signature of an object due to lamp aging, stand off distance and view angle changes. The colorimeter senses and stores values indicative of a sample object (5). The colorimeter includes a processor (80) which then creates an average ratio wherein the stored values and corresponding sensed values are placed in a ratio, all of the ratios are then summed, and the total is divided by the number of values. Finally, the processor compares the sensed values with corresponding stored values, wherein one of the two values is adjusted by the average ratio.

Abstract: A colorimeter provides compensation for changes in the color signature of an object due to lamp aging. A current measuring circuit (95) measures current to the lamp (29) during an initial training of the colorimeter and stores a value I T indicative of the lamp current at training. When an object (5) is scanned by the colorimeter, lamp current is again sensed and assigned a value I S . Comparison between a sensed color signature and a stored color signature then occurs. Compensation is accomplished by modifying one of the two signatures by a ratio including I S and I T power.
