The RT810 Series Analog 2-wire, or loop-powered, temperature transmitters offer the most effective price/performance ratio in the industry.
Factory calibrated for fixed range, they provide a 4-20 mA output linearized to temperature for Pt100.
The wide temperature range and stocked availability make the RT810 an excellent choice for temperature signal transmission.
Precision 20-turn potentiometers allow fine adjustment of ZERO and SPAN. RT810 transmitters are of high quality, very accurate, completely linearized and fit into industry standard connection heads.
