How to calibrate thermocouple devices in
Calibration Services Singapore

  • 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.
