Rosemount™ 148 Temperature Transmitter

The Rosemount 148 Temperature Transmitter is a standard device that can be used with multiple sensor type inputs, providing a cost-effective installation and improved measurement accuracy when compared to wire direct solutions. This transmitter is available in a DIN B style head mount configuration with enclosure and housing options. For reliable performance in process environments, this device has a 4 to 20 mA signal that withstands noise and provides ambient temperature compensation.

About Temperature Transmitters

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.

Advanced Diagnostics

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.
