• Now that it has been established that how
  important proper functioning of thermocouple
  devices is, let us understand the process of its
  Calibration Services Singapore.
• For calibrating a thermocouple device, a graph
  has to be prepared to plot voltage on one axis
  and temperature on the other.

• First, take a thermos-bath with water in it and
  set its temperature to a certain degree, say 30
  degrees. Use the thermocouple device in the bath
  and record the voltage generated by the
  thermos-electrical effect.
• Repeat this activity few more times, each time
  increase the temperature by a degree. Plot the
  graph and draw a slope fitting the data recorded.
  Then refer to the particular thermocouples
  reference table and compare the data. If there is
  a significant difference between the reference
  data and actual recordings then it implies that
  the device is not functioning as per requirement
  and needs to be amended on Calibration Laboratory
  Singapore

Different types of thermocouple devices

• Different metals can be used for creating
  thermocouple devices, therefore there exists
  different combinations of metals which comprise
  the different types of the device.
• There are majorly 8 types of thermocouple
  devices, each has different temperature limits,
  reliability factors, cost of productions and life
  span.

Need to calibrate thermocouple devices

• Temperature is a vital variable for many
  manufacturing and industrial processes.
  Conducting processes in wrong temperatures can
  result in production of defective and substandard
  products. To assure perfection in such process
  industrialists use thermocouple devices in
  Calibration Company Singapore.
• But what if the device itself is defective.
  Defective thermocouple devices can indicate wrong
  temperatures. If the wrong temperatures are not
  identified and are falsely assumed to be the
  correct temperature, then it can cause serious
  problem with the manufacturing process.
  Therefore, to avoid such problems it is important
  to check from time to time, that the
  thermocouples are functioning properly.
