The DTN2070 Class 1E absolute and gauge pressure transmitters are designed for harsh nuclear environments and manufactured by Ultra Electronics, Energy. The transmitters provide precision pressure measurements in nuclear applications requiring reliable performance and functional safety. The instruments are Class 1E qualified to IEEE 323-1974 and IEEE 344- 1987. The DTN2070 contains only analog electronics utilizing a diaphragm isolated direct coupled strain gauge pressure sensor capsule. The DTN2070 is updated to meet the most stringent environmental requirements of Gen III+ reactors for harsh operating environments and post-accident monitoring applications inside containment.
The DTN2070 has undergone its own complete seismic and environmental qualification. While the transmitter has been updated over the years to improve performance and to deal with component obsolescence, the sensing capsule of the DTN2070 (Westinghouse Veritrak/ Tobar/ Camille Bauer Model 32, and most recently Weed Instrument DTN2010 and N97) is the same basic field proven design as the Model 32 originally qualified in 1982.
