An industry-standard solution, the Rosemount 248 Temperature Transmitter delivers consistent and reliable performance for process environments. Engineered to meet requirements for common single point temperature measurements, its compact DIN rail design allows for easy installation and use in a wide range of applications.
Emerson’s Rosemount™ 248 and 644 Rail Mount Temperature Transmitter product offering is designed with enhanced features for greater ease-of-use, increased accuracy and reliability, and better insight into your temperature measurements.
New features and capabilities deliver a better user experience:
• LED Indicator gives visibility to the health status of your transmitter and sensor
• Slimmer Form Factor (23.5 mm) allows you to fit more measurement points per rail for more efficient space utilization
• Unique QR Code Asset Tags on newly shipped devices enables you to access serialized information directly from the device
Get more accurate and insightful temperature measurements:
• CVD Transmitter–Sensor Matching improves accuracy by up to 75% by trimming transmitter to specific RTD calibration schedule
• Dual Sensor Functionality increases uptime and measurement insight by providing measurement redundancy and visibility into sensor health (Rosemount 644 only)
• Hot Backup allows for a seamless transfer from a failed sensor to a backup sensor
• Sensor Drift Alert indicates sensor issues before failure
• Calculated Outputs allow for average or differential temperature measurement
