Description
The Rosemount 248R is a DIN-rail temperature transmitter with HART 7 that converts a single RTD, thermocouple, millivolt or resistance input into a 4–20 mA signal, with ±0.20 °C plus 0.10% of span accuracy on a Pt100. It runs on 7.5–48 V DC, provides 2.5 kV galvanic isolation and works from −50 to +85 °C.
Callendar-Van Dusen sensor matching improves system accuracy, and NAMUR-compliant diagnostics support asset management.
