Abstract
A detecting element for determining a parameter, including an electrically resistive body formed on a surface of a support, a conductor electrically connected to the resistive body, and a bonding member for securing the conductor to the support. The bonding member has a low-conductivity portion having a lower thermal conductivity than a remainder thereof, to minimize heat transfer from the resistive body to the conductor via the bonding member.
Claims21
A detecting element for determining a parameter, comprising:
- a support having a bearing surface;
- an electrically resistive body formed on said bearing surface of said support;
- conductor means electrically connected to said electrically resistive body;
- bonding means for securing said conductor means to said support, said bonding means consisting of a porous glass structure which has pores formed therein as at least a part of a low-conductivity portion having a lower thermal conductivity than a remainder of said bonding means which consists of a glass.
