NEW! S1 Series CSA, ATEX, IECEx, SIL Approved Stator Winding RTDs

Insert these thin, laminated RTDs in stator 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. These models are designed for use in hazardous areas, where there may be a presence of flammable gas under normal operating conditions. Strict construction guidelines prevent arcing.

Choose between wire-wound or thin-film sensing elements:
• Wire-wound elements are the standard for use in stator winding temperature sensors since the temperature sensitive length extends nearly the entire sensor body length. 
• Thin-film elements are effectively point sensors, with a temperature sensitive length of approximately 0.1”. Thin-film elements are generally not recommended for stator sensors longer than 4”, but are required for stator sensors under 2” long. These short sensors are also appropriate for installation within the motor/generator winding’s end turns.
