Used for surface temperature measurement, this surface mount RTD sensor measures -328 to 500°F (-200 to 260°C) with a 100 Ω wire-wound platinum element in a thin, flexible polyimide body. It offers ±0.25% tolerance in a 3-wire build with a 70 ms response and minimal thermal mass. It bonds to surfaces with epoxy adhesive and has 36" (91.4 cm) of 26 AWG PVA-insulated leads.

OMEGA's SRTD-1 and SRTD-2 are polyimide insulated surface mount RTD temperature sensors designed to provide a practical method for measuring surface temperature. These sensors are small, flexible, and their low mass has minimal thermal effect on the material being measured. They are ideally suited for applications where the sensor can be mounted to the surface being measured using adhesives or other mechanical mounting methods.
