The RS485 interface, used for CT, CTlaser, and CTratio pyrometers, is a robust and flexible communication standard for infrared temperature monitoring in industrial environments. Operating in a half-duplex mode over two wires (A and B), it supports differential signaling, which enhances noise immunity and allows communication over distances up to 1200 m. Up to 32 pyrometers can be connected on a single bus, facilitating networked temperature monitoring. The RS485 standard typically operates at baud rates up to 921.6 kbps, with standard settings at 115.2 kbps. Proper termination with a 120-ohm resistor at the last infrared sensor prevents signal reflections, ensuring reliable data transmission. This interface allows for precise and efficient infrared temperature data collection, which is essential for applications requiring digital infrared temperature readings.
