DESCRIPTION
The Model JH240 2-wire transmitter provides a 4/20mA current loop output proportional to temperature as measured by a 100 ohm platinum RTD (resistance thermometer). A fixed-range device, it is precisely calibrated to your specified input range at the factory. (For a rangeable 2-wire RTD transmitter see Model JH245.) RTD linearization is provided. Three-wire input circuitry eliminates errors due to lead wire resistance.
