The low temperature platinum thermal resistance bulb is used to the measurement and monitoring for the temperatures of lubricating oil, cooling water, and bearing of various ship-engines as well as the air temperature. Since the delay characteristic (response speed) is most important factor for low temperature use, this thermal resistance bulb is so designed that its resistance element keeps excellent heat conductivity to minimize heat which may otherwise develop in it. The adoption of double protection tube does not affect the characteristics, maintaining the same characteristics as those of single protection tube types.
