The preferred method of temperature measurement for pharmaceutical
validation purposes is the copper/Constantan thermocouple, more
commonly known as the type ‘T’ thermocouple.
This thermocouple was developed for use within the range of –40 to
+350°C and generates a higher mV output per °C than other
thermocouples in this temperature range. The tolerance value for this
thermocouple is also considerably better than that of other thermocouple
types.
Where there are a larger number of thermocouples to be positioned
within a chamber for temperature mapping purposes, it is worth
considering using a loom. This approach assists in the general handling
of the thermocouples and helps prevent damage when installing them in
the chamber.
The loom is produced to the customers required length with all
conductor pairs held within cable ties, these should removed following
installation.
