Used for measurement and monitoring of lubricating oil, cooling water, bearings and outside air temperature of various marine engines. Of the various performances required for low temperatures, delay characteristics (response speed) are emphasized, so a mechanism for reducing the heat capacity and improving heat conduction of the resistance element has been incorporated into the structure. Compared to a single tube, it exhibits inferior characteristics.
