Temperature transmitter

Temperature transmitter

Yokogawa temperature transmitter is the high performance temperature

transmitter that accepts Thermocouple, RTD, ohms orDC milivolts inputs and converts it to a 4 to 20 mA DC

signal for transmission. The YTA110supports either BRAIN or HART communication protocol.

The YTA110 in it standard configuration is certified by TU ¨ V as complying with SIL2 for safety requirement.


Standard specification :


Accuracy

(A/D accuracy/span + D/A accuracy) or  0.1 % of

calibrated span, whichever is greater.


Cold Junction Compensation Accuracy

(For T/C only)

± 0.5˚C (± 0.9 ˚F)


Ambient Temperature Effect (per 10 ˚C change)

± 0.1 % or ± (Temperature Coefficient /span),

whichever is greater. See Table 2. for Temperature

Coefficient.


Stability

RTD:

0.1% of reading or 0.1°C per 2 years,

whichever is greater at 232°C.

T/C:

0.1% of reading or 0.1°C per year,

whichever is greater at 232°C.


5 Year Stability

RTD:

0.2% of reading or 0.2°C,

whichever is greater at 232°C.

T/sC:

0.4% of reading or 0.4°C,

whichever is greater at 232°C.
