Temperature Mapping / Validation / Temperature Uniformity Testing of furnace / ovens , cold chambers etc
This is done by locating various temperature sensors inside the equipment. These are connected to data logger. When actual temperature reaches to desired set temperature , it allows to stabilize & after thermal stabilization temperature readings are noted for 30- 40 minutes or as per requirement. These methods are based on various National & International standards.
System Accuracy Testing & Loop Testing
System Accuracy test is basically to verify the total measuring system. In this case dry block calibrator is used to simulate the furnace temperature. The furnace temperature sensor is inserted in the dry block calibrator along with our master sensor & temperature is set to desired temperature. While carrying out the activity temperature of master sensor is noted & output of furnace thermocouple, temperature indicators etc are checked & compared with master sensor.
In this system, Flow & Temperature is measured by Calibrated instruments. These measured values are used to calculate Energy. This calculated value of Energy and reading of device under calibration is compared.
