Mounting
Transmitters may be attached directly to the sensor. Optional mounting brackets (codes B4 and
B5) permit remote mounting. See
Optional Transmitter Mounting Brackets on page 204 .

A.1.3 Performance specifications
Stability

±0.1% of reading or 0.1 °C, whichever is greater, for 24 months for RTDs.

±0.1% of reading or 0.1 °C, whichever is greater, for 12 months for thermocouples.
5 year stability

±0.25% of reading or 0.25 °C, whichever is greater, for 5 years for RTDs.

±0.5% of reading or 0.5 °C, whichever is greater, for 5 years for thermocouples.
Vibration effect
Tested to the following with no effect on performance:
Self calibration
The analog-to-digital measurement circuitry automatically self-calibrates for each temperature
update by comparing the dynamic measurement to extremely stable and accurate internal
reference elements.
RFI effect
Worst case RFI effect is equivalent to the transmitter’s nominal accuracy specification,
according to
Accuracy on page 194 , when tested in accordance with ENV 50140, “30 V/m
(HART) / 20 V/m (HART T/C)” / 10 V/m (F
