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.
Weight
Enclosure ratings
NEMA 4X, CSA Enclosure Type 4X, IP66, and IP68.
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
OUNDATION fieldbus), 80 to 1000 MHz, with unshielded
cable.
CE electromagnetic compatibility compliance testing
The 3144P meets all requirements listed under IEC 61326: Amendment 1, 2006.
