Overview 

The Rosemount 648 Wireless Temperature Transmitter offers best-in-class wireless accuracy and stability for process monitoring.
This durable transmitter is designed with a dual-compartment housing for field reliability. When combined with Rosemount X-well™
Technology and the Rosemount 0085 Pipe Clamp sensor, this transmitter can provide accurate measurement of process temperature via an in-transmitter thermal conductivity algorithm, eliminating the need for a thermowell or process penetration.

Benefits

* WirelessHART® technology is secure, cost-effective and delivers >99% data reliability
* Best-in-class wireless accuracy and stability for process automation
* Durable dual-compartment housing offers added field reliability
* Rosemount X-well Technology measures temperature without a process penetration for reduced design, installation and maintenance costs
* Transmitter-sensor matching produces better accuracy, matching exact sensor characteristics with the transmitter
* LCD display offers access to measurement and diagnostic information in the field, enhancing process visibility
* SmartPower™ module provides up to 10-year maintenance-free operation and field replacement without transmitter removal
* Easy installation enables quick instrumentation of measurement points without the cost of wiring.
