RTDs are designed for applications that require critical temperature measurement for small-diameter lines in sanitary processes. The RTDs cover temperature range from -58 to 392°F (-50 to 200°C) with ± 0.10 percent accuracy at 32°F (0°C). Time constant is 1.5 sec max for 63.2 percent response to step change of temperature in water moving at 3 ft/sec. Insulation resistance is 500 MW at 100 VDC. Repeatability is less than ± 0.01 percent change in ice point resistance after 10 consecutive cycles from -58 to 392°F.
