Description

The Rosemount 248R Temperature Transmitter is engineered as a DIN rail-mounted unit, providing flexible installation in control panels and junction boxes. It supports a wide range of input types including 2-, 3-, and 4-wire RTDs, thermocouples, millivolt, and ohm signals, allowing compatibility with various temperature sensing elements. With a reference accuracy of ±0.20°C or ±0.1% of span and a fast update time of less than 0.5 seconds, it ensures reliable and responsive temperature measurement in dynamic process conditions.

In addition, the transmitter features 4–20 mA output with HART protocol for easy integration into distributed control systems (DCS) and asset management platforms. It operates within a temperature range of -40°C to 85°C and includes input/output isolation up to 500 Vac for enhanced safety and signal stability. Built-in diagnostics such as open/short sensor detection help identify faults early, reducing downtime and maintenance costs. Its PC-programmable interface and compact design make configuration simple while lowering overall installation costs compared to direct sensor wiring.
