PERFORMANCE

Accuracy: [Table 1 Accuracy value + Cold Junction

Compensation Error 0.5°C (0.9°F)] or ±0.1 % of span,

whichever is greater.

Add 0.2 % when the output span equals 1/10 or narrower of

the max. span.

Cold junction compensation error:

±0.5°C at 25 ±10°C

±0.9°F at 77 ±18°F

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span

at -5 to +55°C [23 to 131°F]

Response time: ≤ 0.9 sec. (0 – 90 %)

Burnout response: ≤ 10 sec.

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @1 minute (input to output

to power to ground)

CALCULATION EXAMPLES OF OVERALL ACCURACY

[Example 1]

Input: K thermocouple, 0 – 1000°C, Output: 4 – 20 mA DC

1) Absolute value accuracy (Table 1): 0.25°C

2) CJC error (0.5°C) added: 0.75°C

3) 0.75°C ÷ 1000°C × 100 = 0.075 %

4) 0.075 % < 0.1 % of span. ➠ 0.1 % is selected.

5) Output span 16 mA (= 20 mA – 4 mA)

Max. span 20 mA

Output span ≥ 1/10 of max. span ➠ No need of adding

0.2 %.

6) Overall accuracy equals ±0.1 % of span

[Example 2]

Input: K thermocouple, 50 – 150°C, Output: 2.0 – 2.5 V DC

1) Absolute value accuracy (Table 1): 0.25°C

2) CJC error (0.5°C) added: 0.75°C

3) 0.75°C ÷ (150 – 50)°C × 100 = 0.75 %

4) 0.75 %> 0.1 % of span. ➠ 0.75 % is selected.

5) Output span 0.5 V (= 2.5 V – 2.0 V)

Max. span 5 V

Output span ≤ 1/10 of max. span ➠ Add 0.2 %.

6) Overall accuracy equals ±0.95 % of span (0.75 + 0.2)
