Classification: CPC B  G | IPC B  G

Claim 16:
17. A system for temperature sensing and control of a heating element, the system comprising:
a) a controller;
b) a transducer;
c) a power source;
d) a heat seal bar including the heating element;
e) a sensor that is adapted to be positioned on the heat seal bar so that it is in contact with the heating element during calibration of the heat seal bar and adapted to be removed from the heat seal bar after calibration of the heat seal bar;
f) wherein during a calibration cycle, the controller provides calibration values based on temperature readings gathered from the sensor and resistance readings that are calculated by the controller based on current voltage and current feedback signals received from the transducer; and
g) wherein during a heat seal cycle, after the sensor is removed in step “f”, resistance readings are calculated by the controller based on current voltage and current feedback signals received from the transducer and the controller converts the resistance readings to temperature readings based on the calibration values to enable monitoring of temperature of the heating element during the heat seal cycle.
