6-1. Maintenance
To maintain accurate measurements, the following is recommended:
1.
Check for any air space and/or skinning of the sensor at the time of installation.
2.
Check for any damage on the sensor and lead wires.
6-2. Calibration and Tr aceability
1. Calibration Method
The calibration of these heat flow sensors are performed at EKO according to the following procedure.
1)
Set the calibrating heat flow sensor in between high temperature and low temperature plates.
2)
Set the high temperature plate to 45℃ and low temperature plate to 15℃ and start the calibration
measurement.
3)
Taking approximately 3 hours, achieve static state where the outputs become constant among the high
temperature plate, low temperature plate and the calibrating heat flow sensor.
4)
Measure the output voltage from the calibrating heat flow sensor, and calculate the sensitivity using
following formula:
k＝E/Q
Where
K:
Sensitivity of Calibrated Heat Flow Sensor
E:
Output Voltage of Calibrated Heat Flow Sensor
Q:
Heat Flux measured using Reference Heat Flow Sensor.
