Title:
エンジンの高温部測定装置
Document Type and Number:
Japanese Patent JP7428462
Kind Code:
B2
Abstract:
To reduce measurement cost by reducing measurement accuracy and responsiveness within a permissible range, relating to a device for measuring the temperature of a high temperature portion such as a combustion chamber.SOLUTION: A measurement device 1 is composed of a holder body 2 and a cap 3 provided at the distal end of the holder body, with a sensor housing unit 13 formed at the distal end of the bolder body 2 while the sensor housing unit 13 is opened forward. The cap 3 is composed of a cylindrical body 17 and an end plate 18. The end plate 18 is made of a metal such as copper, having high thermal conductivity, and is close to or in contact with the distal end face of a temperature sensor 12. The temperature sensor 12 is repeatedly usable since it is not exposed to a combustion gas. The end plate 18 has high thermal conductivity, therefore the temperature can be measured accurately and with good responsiveness even by an indirect measurement method by correcting an actual measured value. Running costs can be significantly reduced since an expensive temperature sensor is repeatedly usable.SELECTED DRAWING: Figure 1
