Resistance temperature sensor S100050 PD

ATEXstator windingfor hazardous areas

Insert these thin, laminated RTDs in winding slots to detect high temperatures before insulation damage occurs. RTD temperature sensors continuously monitor conditions and provide the long term trend data that is necessary for making adjustments before unexpected alarms occur. The sensing elements of stator RTDs extend through most of the body length to provide an average temperature reading. This eliminates the danger of a point-type sensor missing a localized hot spot. Six sensors are recommended for each motor, two per phase. Locate sensors near the hottest point of the windings for best performance. Some models comply with European standards for electrical apparatus for potentially explosive atmospheres: ATEX Directive 94/9/EC EN 50 014: 1997, General requirements EN 50 019: 2000, Increased safety.
