5.3 HEATER BLOCK:
The “Block” is made of Inconel 600 provides a relatively constant and
accurate temperature environment in which the sensor that is to be calibrated is
inserted. A 0.25 inch diameter well is provided that may be used for sensors of
that
size or may be sleeved down with various sized multi-hole probe sleeves. Heaters
surround the block assembly and provide even heat to the sensor. K type simplex
Thermocouple is embedded at the base of the block assembly
to sense and control
the temperature of the block. The entire assembly is suspended in an air cooled
chamber thermally isolated from the chassis and
electronics.

Operational Procedure
Connect the dry block calibrator to the power socket & Insert the Inconel block in
the furnace
Switch ON the instrument with MCB.
Set the required temperature in the PID Controller as follows.
Press “*” key and “
▲
“key simultaneously to increase the set temperature.
Press “*” key and “
▼
“key simultaneously to decrease the set temperature.
Insert the sensors, which are going to be calibrated into the corresponding hole
of the Inserts.
Allow the bath to stabilize at the set temperature.
Connect test probe to the indicator and note down the readings of test probe.
Repeat Steps d to h for other set of calibration points.
After calibration is over, set the bath temperature to ambient and allow the bath
to cool.
When Bath temperature reaches 200˚C, switch off the power supply.
