Emerson 248HANAU2XAF6

Emerson's Rosemount 248 Head Mount Temperature Transmitter (model 248HANAU2XAF6) delivers reliable single-point temperature measurement in industrial processes by converting a wide range of sensor inputs to a standard 4-20 mA current loop with HART communication. It accepts sensors including 2-, 3-, and 4-wire RTDs, thermocouples, millivolt sensors, and resistance (ohm) inputs, with transmitter-sensor matching based on Callendar-Van Dusen constants to minimize total measurement error. The transmitter features a one-year stability rating to reduce maintenance and provides open/short sensor diagnostics and device dashboards for straightforward configuration and troubleshooting. Built to withstand common process environments, the Rosemount 248 head-mount design is available with multiple housing options and compatible conduit entries (M20 x 1.5 or 1/2-14 NPT) via accessory heads, allowing flexible installation. This model is part of the Rosemount 248 temperature transmitter family, a trusted standard for single-point measurement in challenging industrial settings.
