Emerson's industry-leading Rosemount Temperature Transmitters are engineered for performance, helping to obtain accurate and reliable measurements even in the most challenging applications. Choose from various housing styles to meet your application needs and utilize the Advanced Diagnostics capabilities to gain insight into your process for safer and more efficient operations.
Our Rosemount Temperature Transmitter portfolio offers innovative, industry-leading technologies engineered to meet the demands of tough environments and challenging applications. These transmitters help ensure accurate and reliable measurements to support the safety and efficiency of your operations. For application flexibility, our temperature transmitters can transmit a hard-wired or wireless signal and be mounted and configured locally or remotely. Every Rosemount temperature transmitter is compatible with all industry-standard resistance temperature detectors (RTD) and thermocouples.
Temperature transmitters act as a medium between the sensor and a control system. Used in a variety of industries, they accept signals from all industry-standard resistance temperature detectors (RTD) and thermocouples, converting measurement input signals to a 4-20mA, HART, WirelessHART®, or FOUNDATION™ Fieldbus output signal. They can be calibrated to a desired temperature measurement range and configured to alert the control system if the process temperature falls outside of the specified range. Available in many housing styles and enclosures, these devices can be mounted with a sensor/thermowell assembly at the measurement point or mounted remotely.
Protect Your Temperature Measurement Against Numerous Disruptors:
Temperature Transmitters improve performance by filtering out environmental noise (1) and compensate for inaccuracies caused by corroded terminations (2) and frayed wiring (3). Field Mount housings can prevent the presence of moisture in the electronics compartment (4). A calibrated transmitter-sensor assembly can fulfill performance requirements in custody transfer and safety-related applications. Advanced Diagnostics help avoid measurement failure and process shutdown by identifying failing or degrading sensors (5) and connections (6).
Utilizing the Advanced Diagnostics Capabilities of Rosemount Temperature Transmitters enhances the quality and accuracy of your temperature measurements. Environmental and installation effects that can create erroneous measurement values can be compensated and filtered out by these diagnostic capabilities. Our diagnostics can also be used to alert you of a degraded sensor or installation condition prior to sensor failure. The measurement insights gained by using advanced diagnostics help to maintain process measurement uptime, allow for proactive maintenance, and ultimately, help avoid an unforeseen process shutdown.

Reduce process control disruption with Hot Backup Capability. This dual-input diagnostic prevents loss of measurement due to primary sensor failure. Unexpected failure of temperature measurement can cause safety, environmental or regulatory concerns and process shutdowns. With Hot Backup, the transmitter automatically sends a maintenance alert during primary sensor failure and switches the output to a secondary sensor without impacting your measurement signal.
Thermocouple Degradation continuously evaluates thermocouple loop status. Thermocouple loops are often installed in high temperature processes where shutdowns are expensive and can be compromised by wire thinning, sensor degradation, and corrosion. Thermocouple Degradation monitors thermocouple loop resistance, detects degrading sensors before failure, and provides alerts when a user-specified resistance limit is exceeded.
Open/Short Sensor Diagnostic alerts you to open or shorted sensor failure, the most common of sensor failures. These failures can be caused by shock, vibration, corrosion, wire thinning, bent wiring or contamination. This feature recognizes the sensor failure and generates an alarm to alert a need for maintenance, preserving measurement accuracy and health.
Maintain measurement integrity with the Sensor Drift Alert. This dual-input diagnostic detects the condition of degrading sensors on a transmitter. During sensor degradation, the temperature reported can drift from the actual value. This diagnostic monitors the two sensor readings continuously and when the difference in the reading between the two sensors exceeds a user-specified limit, the transmitter sends you an alert to indicate the status of the degrading sensor.
Ease troubleshooting efforts with a Diagnostics Log, a historical log of device alerts and alarms. This feature maintains the identity of the alarm or alert even when a temperature transmitter alarm quickly disappears. The Diagnostic Log records which alarms and alerts have occurred since the last device reset and provides access to the alarm information regardless of how brief, providing you added device status insight and simplifying maintenance.
Keep your processes running with Open Sensor Holdoff, a diagnostic that prevents false open sensor events from disrupting process control. High voltage transients, such as lightning and electrostatic discharge, can cause false open sensor alarms. With this diagnostic enabled, the transmitter waits for several updates to determine if an actual open sensor event has occurred before triggering an alarm.
Min/Max Tracking proactively monitors temperature extremes, which aids in the troubleshooting of quality issues. This feature provides access to records of ambient and output temperature extremes. Ambient temperature tracking verifies that installation temperatures have not exceeded recommended operation limits. Min/Max Tracking monitors output temperatures, which can be used to ensure optimal temperatures are not exceeded in order to preserve process quality.
Prevent induced voltages from affecting your measurement accuracy with EMF Compensation. In RTD measurement loops, small voltages known as EMFs can be induced on sensor wires, increasing the effective resistance and causing false temperature readings. The EMF Compensation diagnostic detects and eliminates erroneous voltages commonly caused by external factors, such as motors, calibration devices, corroding terminals or damaged sensor wiring.
The Transient Filter diagnostic prevents intermittent sensor conditions from affecting accuracy. When subjected to a high vibration or a noisy environment, a temperature sensor can often report false temperature spikes. The Transient Filter recognizes and rejects these incorrect, intermittent temperature readings and filters out incorrect temperature spikes to minimize disruptions in process control.
The Line Voltage Filter provides temperature measurement protection from AC voltage effects. Temperature sensors can easily pick up noise from a 50Hz or 60Hz AC voltage source, and the transmitter can interpret this AC voltage interference as part of the measurement, causing an incorrect temperature reading. The Line Voltage Filter recognizes the AC voltage interference and filters out the noise for a more accurate reading.
