Rosemount 848T Wireless High Density Temperature Transmitter
1. Product Overview
- Four independently configurable RTD, thermocouple, ohm, millivolt and 4 - 20 mA signals
- Lowers installed cost by eliminating long wire runs to the control room
- Dependable performance by enhancing measurement reliability for trustworthy data - Mount close to process to keep sensor wiring short to minimize effect of electromagnetic interference(EMI)
- Transmitters compensate and filter noise and EMI for stable measurement performance
- Simplified installation and configuration practices for faster start-ups - Reduction of required loop drawings, eliminates cable trays and large wiring cabinets
- Enhanced user interface makes configuration intuitive for faster configuration and commissioning
- Fully compatible with WirelessHART networks with greater than 99% data reliability
- Eight user configurable alerts for advanced measurement monitoring
- fluctuations of ambient temperature
- Reference Accuracy ± 0.3°C (± 0.54°F) PT100 @ 20°C
- ± 0.70 °C (± 1.26 °F) for Type J Thermocouple
- Output WirelessHART™
