*1. To convert the temperature unit from Celsius to Fahrenheit, use the following equation.
Fahrenheit temperature (°F) = Celsius temperature (°C) x 1.8 + 32
*2. If there is more than one input range for the same input type, the one with narrower input range has higher resolution.
*3. For a thermocouple input type Temperature Input Unit, the overall accuracy is guaranteed for a set consisting of a cold junction sensor that is mounted on the terminal block and a Temperature Input Unit. Be sure to use the terminal block and Temperature Input Unit with the same calibration control number together. For the 24 mm wide model, also be sure the left and right terminal blocks are correctly attached.

 

NX-TS Specifications 31

 

*4. An error for a measured value when the ambient temperature changes by 1°C.
The following formula is used to calculate the error of the measured value.
Overall accuracy = Reference accuracy + Temperature characteristic x Change in the ambient temperature + Cold junction compensation error (Calculation example) Conditions

 

ItemDescription
Ambient temperature30°C
Measured value100°C
NX UnitNX-TS2101
ThermocoupleK thermocouple

 

The characteristic values are formulated from the data sheet or reference accuracy and temperature coefficient table under the above conditions

ItemDescription
Reference accuracy-100 to 400°C: ±1.5°C
Temperature coefficient-100 to 400°C: ±0.30°C/°C
Change in the ambient temperature25°C -> 30°C 5 deg
Cold junction compensation error±1.2°C

 

Therefore,
Overall accuracy = Reference accuracy + Temperature characteristic x Change in the ambient temperature + Cold junction compensation error
= ±1.5°C + (±0.30°C/°C) x 5 deg + ±1.2°C
= ±4.2°C

*5. The ppm value is for the full scale of temperature range.

Cold Junction Compensation Error Specifications for Units That Take a Thermocouple Input Type

The cold junction compensation error for Units that take a thermocouple input type is restricted as follows according to the installation orientation and the power consumption of adjacent Units *.

 

(a) For upright installation, when the power consumption is 1.5 W or less for both the left and right adjacent Units
The cold junction compensation error is ±1.2°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction
compensation error are as in the table below.

 

Input type and temperature rangeCold junction compensation error
T below -90°C±3.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°CNot guaranteed
W±3.0°C
(b) When the power consumption of either the left or the right adjacent Unit is more than 1.5 W but less than 3.9 W. Or for any installation other than upright, when the power consumption of both the left and right adjacent Units is less than 3.9 W
The cold junction compensation error is ±4.0°C.
However, there are exceptions depending on the input type and temperature. Those conditions and the cold junction compensation error are as in the table below.

 

Input type and temperature rangeCold junction compensation error
T below -90°C±7.0°C
J, E, K and N below -100°C
U, L and PLII
R and S below 200°C
B below 400°CNot guaranteed
W±9.0°C
(c) When the power consumption exceeds 3.9 W for either the left or right adjacent Unit
Do not use the above condition (c) because the cold junction compensation error is not guaranteed in this condition.
* The power consumption of adjacent Units is the total of the following values.
The power consumption of the NX Unit power supply and I/O power supply for the NX Units adjacent to the Temperature Input Unit. If the adjacent Unit is an Input Unit, it is the total power consumption according to the input current.
