1. Sensor Unit (Sensor)
This is the sensor part which measures the VIP.
It is constructed with heater which heats the VIP,
differential thermocouple, thermal resistance
metal and brass spindle weight.
It measures the temperature difference between
the temperature of VIP surface which is heated
with heater and inside the sensor which is
insulated with thermal resistance material.
To compare the output value and the thermal
conductivity, calibration needs to be performed.
