The CHATILLON® STS Series torque sensors are full-bridge strain gauge sensors complete with 15-pin plug.  These sensors are used  exclusively with the Chatillon DFS II-R-ND Series digital indicator.   The sensor’s torque values and sensitivity factors are stored in memory within the sensor plug.  When connected to a DFS II-R-ND indicator, the capacity and calibration points are automatically recognized by the instrument.  The instrument then becomes a full-featured torque measurement instrument.
