FAQ
- A temperature transmitter takes the raw signal from a thermocouple or RTD, linearizes it, applies engineering units, and outputs 4-20 mA or HART to the control system. Used in head-mount (in the sensor's connection head) or DIN-rail (in a control cabinet) configurations. Modern smart transmitters add diagnostics, dual-sensor input for backup, and configuration over HART or fieldbus.
- Three reasons. First, a 4-20 mA signal handles cable runs of hundreds of feet without error - thermocouple and RTD signals start to drift over distance. Second, the transmitter does linearization and cold-junction compensation locally, so the PLC sees engineering units instead of raw millivolts. Third, smart transmitters give you sensor diagnostics, drift detection, and the ability to swap sensors without recalibrating the PLC. The transmitter pays for itself the first time it catches a failing sensor before the process trips.
- A head-mount transmitter installs inside the sensor's connection head (the housing on top of the thermowell). Compact, no extra panel space, and you eliminate the long sensor cable run. A DIN-rail transmitter sits in the control panel on a 35 mm rail, with the sensor wired all the way back. Head-mount for distributed sensors and big plants, DIN-rail for centralized installations and densely sensored skids.
