Product Overview

Engineered for versatility, the Rosemount 644 Temperature Transmitter is available with HART™, FOUNDATION™ Fieldbus or PROFIBUS™ protocols in head, field or rail mount styles with various enclosure options. The optional Local Operator Interface (LOI) enables transmitter configuration in the field without tools.

Key Features
  • Versatile temperature transmitter supporting multiple protocols (HART™, FOUNDATION™ Fieldbus, PROFIBUS™)
  • Flexible mounting options including head, field or rail mount configurations
  • LOI option eliminates need for special configuration tools for field adjustments
  • Transmitter-sensor matching with Callendar-Van Dusen constants improves measurement accuracy
  • Hot Backup™ capability and sensor drift alert ensure measurement reliability with dual sensors
  • Thermocouple degradation monitoring detects potential failures before they occur
  • Min/max temperature tracking for easy troubleshooting of process extremes
  • Intuitive device dashboards simplify configuration and diagnostic processes
