Detailed Introduction

Service intended

Sheathed type RTD is constructed in a way that monolithic resistance element is connected with MI cable (MgO compacted metal sheathed lead wires), and has a longer life and a fast response time. High purity white gold resistance wire is used to perform with a better accuracy. Except the end tip length of 60 mm, it could be bent 2 times more than its out diameter so can be used in the process pipe where it is not easy to install due to the obstacles exist around the installation site.
