The 6331A is a 2-wire programmable transmitter. The transmitter is for conversion of linear resistance variation to a standard analog current signal, for instance from valves or ohmic level sensors.2-wire Programmable Transmitter. 1-channel version, stock-no. 827-5508. 2-channel version, stock-no. 796-6922. Amplification of a bipolar mV signal to a standard 4-20 mA current signal. RTD, TC, Ohm or mV input. Linearized temperature measurement with Pt, Ni or TC sensor. RTD and resistance inputs have cable compensation for 2-, 3- and 4-wire connection. Programmable sensor error value. A limit can be programmed on the output signal. Extremely high measurement accuracy. Galvanic isolation.
