## SILICONE RUBBER SURFACE RTD Temperature Sensor 

## Specifications 

- Fast Response 

- Surface Sensing 

- Noninvasive, Simple Installation 

- Flat, Flexible 

- Custom Dimensions Available 

The Silicone Rubber Surface RTD is a flat, flexible, rectangular sensor with a sensing element laminated in silicone rubber.  They are used to monitor or measure temperature on round or uneven surfaces.  For motor and generator applications, they are commonly used in the end turns of the windings.  Silicone rubber surface RTD sensors are manufactured with plotted element style.  A plotted element allows for measuring the average temperature over an extended area. Measurement Specialties has many sizes available from stock or we can customize to meet your specifications. 

## Features
