In order to measure temperature in a narrow range,
you should choose a suitable thermocouple and wiring which is fully
protected against electric noise. You should also choose a suitable
thermocouple transmitter.
In case of a narrow temperature range, it is especially important
that the thermocouple transmitter has an accurate cold junction compensation
and precise linearization of temperature-emf. M-System Model M2XT
Thermocouple Transmitter meets these requirements.
For cold junction compensation in M-System thermocouple transmitters,
the temperature sensor of high accuracy and little heat mass are directly
mounted on the input terminal. With the measured cold junction temperature,
the compensation is made for each thermocouple type. For linearization,
Model M2XT Transmitter stores the temperature-emf table of each thermocouple
type in 1°C increment. Within each increment, the microprocessor
calculates the measured temperature by proportion. |

Which
thermocouple transmitter do you recommend to accurately measure temperature
in such narrow ranges as 0 to 50°C (32 to 122°F)?
M-System
Model M2XT PC Programmable Thermocouple Transmitter accurately measures
temperature even when the range is as narrow as 0 to 50°C. It uses a
microprocessor to execute accurate cold junction compensation and precise
linearization with the stored temperature-emf tables.
