Devar's fixed range SM811EC series of two wire thermocouple transmitters receive signals from thermocouples and provide a proportional 4-20mA output signal. Because the SM811EC is a two wire device, a single pair of twisted copper wires are all that is required to provide power to the unit as well as to carry the output current.

All SM811EC's are field calibratable, accepting inputs from J or K thermocouples.The zero pot provides an offset adjustment of +/- 25% of the span. The SM811EC's are all provided with upscale thermocouple break indication.
