TEMPERATURE SENSOR AND MULTIPOINT TEMPERATURE MONITORING APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a multipoint temperature monitoring apparatus by which a temperature in many points can be monitored precisely by a method wherein the apparatus is constituted of a first elastic member which surrounds and protects a temperature detection part and whose thermal conductivity is excellent, of a second elastic member which surrounds the first elastic member so as to absorb a shock from the outside, whose elasticity is excellent and whose thermal conductivity is excellent and of an electric wire which is connected to the temperature detection part and which is installed so as to be extended to the outside from the first elastic member. ;SOLUTION: A first elastic member 22 which surrounds and protects a temperature detection part 21 used to measure a temperature inside a temperature monitoring space as an electric change and whose thermal conductivity is excellent is installed. In addition, a second elastic member 23 which is installed so as to surround the first elastic member, which absorbs a shock from the outside, whose elasticity is excellent and whose thermal conductivity is excellent is installed. A heat-resistant electric wire 24 which is connected to the temperature detection part 21, which is installed so as to be extended to the outside from the first elastic member 22 and which is connected to an intermediation device is installed. Thereby, a temperature sensor is constituted. The temperature detection part 21 is an element such as a Zener diode, a thermistor, a thermocouple or the like. A synthetic resin such as a rigid rubber or the like which has an insulating property and which is elastic is used as the first elastic member 22. A cylindrical resin material such as a silicone rubber or the like which is soft and whose shock absorption is excellent is used as the second elastic member 23.;COPYRIGHT: (C)1997,JPO
