Diagnostics
Drift monitoring diagnostic
The temperature transmitter uses two different, thermally coupled sensor elements (NTC, PT 1000) to automatically detect drifts
and errors in the temperature measurement. The temperature transmitter forms an average value using the individual NTC and PT
1000 measured values. It then calculates the deviation of each sensing element to the average. The permissible temperature
deviation is configurable and the transmitter will send alerts/alarms when it is outside the set specification. Different diagnostic
states can be communicated by the transmitter via either the analog signal or a separate configurable switch output.

Sensor backup
If one of the two internal sensor elements fails, the temperature transmitter will continue to communicate the temperature
reading of the remaining sensor to prevent loss of measurement. The transmitter can also send an alert that it is in sensor backup
mode using the switch output on pin 4 (OUT1).
Note
For more information on diagnostic configuration, please see the Rosemount 327T Temperature Transmitter Quick Start Guide
(00825-0100-4329).

Physical specifications
Material selection
Emerson provides a variety of Rosemount products with various product options and configurations including materials of
construction that can be expected to perform well in a wide range of applications. The Rosemount product information presented
is intended as a guide for the purchaser to make an appropriate selection for the application. It is the purchaser’s sole responsibility
to make a careful analysis of all process parameters (such as all chemical components, temperature, pressure, flow rate, abrasives,
contaminants, etc.), when specifying product, materials, options and components for the particular application. Emerson is not in a
position to evaluate or guarantee the compatibility of the process fluid or other process parameters with the product, options,
configuration or materials of construction selected.

Measuring elements
The Rosemount 327T Temperature Transmitter has two sensing elements, an RTD (PT1000) and a thermistor (NTC).
