CALIBRATION OF FLUID BED DRIER TEMP GUAGE

1.0 PROCEDURE :
1.1 Clean the drier, the air filters and exhaust system thoroughly,
1.2 Ensure that the air dampers are kept open fully,
1.3 Ensure that the dial gauge is clean,
1.4 The probes of inlet thermometer and outlet thermometers of the fluid bed drier are kept in oil bath along with standard thermometer and heated to note down the readings at various temperatures.
1.5 Record the temperature shown on the dial thermometer of the drier at an interval of 10 degree centigrade and corresponding temperature on the standard thermometer,
1.6 Calculate the percentage variation and check with the limits,
