AUTROL ATT 2100 SMART TEMPERATURE TRANSMITTER
The ATT 2100 converts various physical temperature values (RTD, Thermocouple, etc.) into a proportional analog current output while also superimposing a digital signal using the HART 7 protocol for remote configuration and diagnostics. Key features include automatic ambient temperature compensation, continuous self-diagnostics, and an optional 3-line LCD display. It is built with a flameproof, IP66/67-rated housing, ensuring reliability and safety in oil & gas, chemical plants, and marine applications. The dual-sensor “Fast Back-up” function ensures uninterrupted operation in critical systems by automatically switching lines if a problem occurs.
