Abstract
A resistance thermometer sensor is provided by forming a path of electrically conducting material secured on an insulating base. The path is shaped as a loop having two side-by-side portions. A shorting bar connecting across these portions to short circuit part of the loop is adjusted along their length to trim the ice point resistance of the sensor as required. When suitably adjusted, the shorting bar is fastened in position, for example by welding. In one example, the sensor comprises a bifilar helix of resistance wire wound and secured on a cylindrical former.
