Specifications and Reference Data
Mounting
The Rosemount 644R attaches directly to a wall or a DIN rail. The
Rosemount 644H installs in a connection head or universal head
mounted directly on a sensor assembly, apart from a sensor
assembly using a universal head, or to a DIN rail using an optional
mounting clip.
Weight
Weight (stainless steel housing for Biotechnology,
Pharmaceutical Industries, and Sanitary Applications)
Enclosure ratings (Rosemount 644H)
All available enclosures are Type 4X, IP66, and IP68.
Sanitary housing surface
Surface finish is polished to 32 RMA. Laser etched product marking
on housing and standard covers.
A.1.3 Performance
EMC (ElectroMagnetic Compatibility)
NAMUR NE 21 Standard
The Rosemount 644 meets the requirements for the NAMUR NE 21
rating.
CE Electromagnetic compatibility compliance testing
The Rosemount 644 is compliant with Directive 2004/108/EC.
Meets the criteria under IEC 61326:2006.
Power supply effect
Less than ±0.005% of span per volt
Stability
RTDs and thermocouples have a stability of ±0.15% of output
reading or 0.15 °C (whichever is greater) for 24 months.
When ordered with the P8 option code:
RTDs: ±0.25% of reading or 0.25 °C, whichever is greater, for 5
years
Thermocouples: ±0.5% of reading or 0.5 °C, whichever is greater,
for 5 years
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.
Vibration effect
The Rosemount 644 HART is tested to the following specifications
with no effect on performance per IEC 60770-1, 2010:
