3144 Emerson Temperature Transmitter PT100 RTD Temperature Transmitter 3144PD1A1E5B4M5T1Q4

Highlights — Features & Functions

Advanced Sensing & Accuracy

• Universal inputs: Accepts RTDs (2/3/4-wire), thermocouples (Types B, E, J, K, N, R, S, T, L, U, W5Re/W26Re), millivolt, and ohm signals
• Single or dual‑sensor mode: Supports differential, averaging, redundant measurement, Hot‑Backup®, and Sensor Drift Alert capabilities
• Transmitter‑Sensor Matching (C2 option): Calibrates with RTD sensor characteristics to reduce interchangeability error by ~75%

Diagnostics & Safety

• Thermocouple loop degradation detection: Monitors for changes in resistance that might indicate wire issues
• Min/max tracking: Continuously logs peak values for both process and ambient temps
• Sensor Drift Alert: Warns if dual-sensor readings diverge beyond preset thresholds
• Hot Backup® (U1 option): Seamlessly switches to backup sensor if primary fails, ensuring uninterrupted output
• IEC 61508 Safety-Certified: HART‑based units certified up to SIL 2 (1oo1 logic) and SIL 3 (redundant 1oo2 setup)
• Independent fail‑safe circuit: In case of processor failure, analog output goes to preset fail‑high or fail‑low state.

Physical & Environmental Design

• Dual‑compartment rugged housing: Offers robust protection (NEMA 4X/IP66/68) against water, dust, wiring noise, and EMI
• Enclosure materials & entries: Low‑copper aluminium or optional stainless steel, with ½‑14 NPT, M20, PG13.5, or JIS conduit options
• Operating & storage range: –40 °C to +85 °C (electronics); –60 °C to +120 °C (storage) .
• Stability specs: RTDs maintain ±0.25 % or ±0.25 °C over 5 years; thermocouples ±0.5 % or ±0.5 °C
• Self‑calibrating ADC and robust EMC performance (IEC 61000‑4‑3 up to 30 V/m test)

Communication & Local Interface

• 4‑20 mA + HART (Rev 5/7) or FOUNDATION Fieldbus (ITK 6.0, NE107) with built‑in AI, PID, and advanced diagnostics function blocks
• Local LCD display: Shows process value and diagnostics graphically; suave configuration and verification onsite

Wiring / Configuration Snapshots

• Single sensor wiring: Standard RTD or thermocouple hook-up diagrams available for HART and Fieldbus modes.
• Dual sensor wiring: Supports dual RTDs, dual T/Cs, or mixed RTD+T/C setups—ideal for ΔT, averaging, or redundant measurements
• Typical response time: ~0.5 s for single-sensor mode, ~1 s for dual sensors.
