Emerson 248RANAQ4 intelligent temperature transmitter

Product Description

Rosemount (Emerson) 248RANAQ4 is a DIN rail mounted smart temperature transmitter from 248R series. It accepts RTD (PT100, PT1000) and thermocouple inputs, equipped with HART 7 protocol. It converts temperature sensor signals to standard 4-20mA analogue output. Compact rail housing for cabinet installation, with sensor wire-break detection, self-diagnosis and custom range configuration. Explosion-proof options available. Widely used in chemical, oil & gas, water treatment and power plants for temperature measurement and transmission to DCS / PLC, commonly used spare part for thermal process loops.
