ある。"Problems to be solved by conventional techniques and ideas" The nominal resistance value of a resistance temperature detector is specified in JIS-C1604.
Pt is specified as 100Ω or 50Ω, but in order to measure temperature more accurately, for example 500Ω,
Setting a nominal resistance value such as 1000Ω will give a larger measured value and improve accuracy. However, increasing the resistance increases the size and shape of the threaded resistance element, which increases the heat capacity and reduces measurement accuracy, and also makes it difficult to obtain fine platinum wire. There are also problems due to limitations in the technology for winding ultra-fine platinum wire.

測温抵抗体である。"Means for Solving the Problems" In view of the above circumstances, the present invention is a method to create a high-resistance resistance temperature detector using multiple small resistance elements that have recently become smaller and more easily available.

The end of the lead wire of the small resistance element is connected to the end of the lead wire, and ceramic cement is placed in the end of the small resistance element and the recess between the small resistance elements. It is a coated high resistance temperature measuring resistor.

The plurality of small resistance elements are arranged on the outer peripheral surface of an insulator through which a lead wire is inserted, and the lead wire end of the small resistance element and the end of the lead wire are connected, and the end of the small resistance element The present invention is a high-resistance temperature measuring resistor in which ceramic cement is applied to the recesses between the small resistive elements, and although it has high resistance, it is easy to downsize and improves temperature measurement accuracy.

The insulator 5 serves as a reinforcing member and is resistant to vibration while being compact. Further, by adjusting the length of the lead wire of the small resistance element, the combined resistance value can be changed, so that it is possible to use an element whose resistance value does not meet the standard.
