The 22810 polyimide insulated flexible RTD Stikon® surface sensor series from RdF is designed to provide a practical method for measuring surface temperature. The standard sensing element is platinum with a resistance of 100Ω at 0°C with a TCR of 0.0038 Ω/Ω/°C nominal and an operating temperature range -200°C to +232°C. The 22810 sensor series from RdF are small, flexible and their low mass has a minimal thermal effect on the material being measured. They are ideally suited for applications where the device can be permanently mounted using adhesives or other mechanical mounting methods.

Operating temperature range -200°C to +232°C with permissible exposure to 260°C for short periods clamped
Standard accuracy of ±0.5Ω 0.5% of temperature. (Optional accuracy of ±0.22Ω 0.25% of temperature)
Time response of 200ms lag on metal surfaces
Platinum sensing element with a resistance of 100Ω at 0°C
TCR of 0.00385 Ω/Ω/°C nominal (IEC751)
Stability of less than 0.2°C drift per year at a rated service temperature with proper mounting
The bare sensor will rise less than 1°C while dissipating an I²R power of 15mw on metal surfaces
Stranded nickel plated copper conductors with PFA Teflon® insulated 3 or 4 conductor ribbon cable
The insulation resistance between the outer sensor insulation clamped between 2 metal plates and the common lead wire is 50MΩ minimum with 50VDC applied to a dry sensor at room temperature.
Mounting will conform to surfaces with radii down to ⅜ inch transverse to the element winding and 1½ inch longitudinal to the winding
