Overview

Silicon rubber surface RTDs 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.

Features

  • Temperature range: -50°C to 220°C (-58°F to 428°F)
  • Elements: Platinum, Copper, Nickel; Style: Plotted
  • Optional adhesive backing
