Two easily overlooked, yet extremely critical parameters when evaluating and specifying torque transducers are – Mechanical Overload Rating and Electrical Overrange.  Each is important, but often confused and misunderstood.

Overload – represents a mechanical safety factor for the sensor element.  Normally expressed as a percentage of the sensor full scale rating, it is the maximum load limit of the sensor before yield or physical deformation.  S Himmelstein and Company products are available in a variety of overload ratings – typically either 200%, 400% or even 1,000%.  

Overrange – is a parameter that relates to the sensors’ electrical output signal.  Also expressed as a percentage of the sensor full scale rating, it represents how far the output voltage will extend beyond full scale.  The majority of S. Himmelstein and Company sensors now incorporate integrated signal conditioning electronics for processing of the sensor strain gage signal.
