Rosemount 3144P
A-2
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 A-12.
Weight
Enclosure Ratings
NEMA 4X, CSA Enclosure Type 4X, IP66, and IP68.
Performance
Specifications
The 3144P maintains a specification conformance of at least 3 σ.
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 Table on page A-4, when tested in accordance
with ENV 50140, 30 V/m (HART) / 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,
1998.
