Honeywell Smartline Temperature Transmitters

Temperature transmitters take a weak, low voltage RTD or thermocouple temperature sensor signal, and convert it to a strong and stable analog signal more appropriate for long-distance transmission through an industrial or commercial plant for direct interface with an indicator, recorder, PLC, DCS or PC-based SCADA system.
