The Rosemount 848T temperature transmitter provides a top-notch solution for high-density temperature measurement applications. It is the ideal transmitter for obtaining up to 8 closely spaced temperature measurement results, reducing wiring costs and simplifying installation. This transmitter features Emerson's measurement validation diagnostics, which can help you predict scale failures and avoid unnecessary downtime, thereby enhancing safety and productivity.

 Here are the key features of the Rosemount 848T Temperature Transmitter that make it a standout for high-density temperature measurement:

Eight independently configurable inputs: Supports RTDs, thermocouples, ohm, millivolt, and 4–20 mA signals—perfect for clustered measurement points.

FOUNDATION Fieldbus or WirelessHART communication: Offers flexible integration into digital plant architectures.

Measurement validation diagnostics: Detects sensor drift, wiring issues, and abnormal process conditions to prevent failures before they happen.

High accuracy: ±0.30°C for Pt100 RTDs and ±0.70°C for Type J thermocouples.

Fast update rate: Reads all eight inputs in approximately 1.5 seconds.

Compact, field-mountable design: Reduces wiring costs and improves signal integrity by placing the transmitter close to the process.

Robust construction: Tested for high pipeline vibration and operates in 0–99% non-condensing humidity environments.
