Sensor No.Location In The ChamberJustification For Location Selection
1In the active Chamber Drain (Near RTD -01)This is the location for the reference measurement point of the sterilizer, which controls the sterilization cycle. Hence important to compare the achieved temperature distribution results (strip chart/printout of sterilizer) with the results from the data logger.

(NOTE: The temperature sensors shall be placed in the pre-determined locations with predetermined sensor numbers corresponding to the data logger channels).

NOTE: It is not possible to insert the temperature sensors in the Rotating carriage of the bung processor during Sterilization and drying as the carriage rotates during the sterilization and drying process. Hence the basket drive of the equipment has been intentionally stopped and the sensors are introduced into the static carriage during this heat penetration study. This simulates the worst case study of stationary load for sterilization and drying.
