Hello Everyone,
2-wire Temperature Transmitter Details:
1.Model: TxisoBlock
2.Make: Novus
3.Accuracy: 0.3% of full span
4.Range: Configured for 0-600 deg C
5.Input: K type thermocouple
6.output: 4-20mA DC
I have used Multifunction Calibrator (PROVA 123) and RishMulti18s 5 and half digit Multimeter for Temperature transmitter testing.
I have applied a K type thermocouple input through
PROVA 123 And reading as follows<pre>
S.No Std Input/ Std Output/ Observed Output/ O/P Error/
1 /0 /4 /4.086 /0.54
2 /150 /8 /8.074 /0.46
3 /300 /12 /11.995 /-0.03
4 /450 /16 /15.947 /-0.33
5 /600 /20 /19.939 /-0.38</pre>
Except 12mA, All readings are out of Accuracy.
I thought Multifunction Calibrator also has some Accuracy. I have applied input like Actual Input in Below table <pre>
S.No/ Std Actual Input Std Observed O/P
Input Input Error Output Output Error
1/ 0/ -1/ -0.17/ 4/ 4.048/ 0.30/
2/ 150/ 149/ -0.17/ 8/ 8.024/ 0.15
3/ 300/ 300/ 0.00/ 12/ 12.01/ 0.06/
4/ 450/ 450/ 0.00/ 16/ 15.967/ 0.21/
5/ 600/ 601/ 0.17/ 20/ 9.974/ 0.16/ </pre>
Which table is Correct?
If table two is correct then Advice How Can i Justify it?
Kindly Advice
Thanks and Regards,
