Title: Platinum temperature sensor
Inventor: MORIYA SATOSHI
IPC: G01K7/18
Filed: 1993-04-14
Abstract: PURPOSE:To constitute a platinum temperature sensor having a small step area and a high temperature coefficient in which the resistance can be adjusted over a wide range at a low cost by making a cut in a resistor formed by firing a platinum organic compound between the electrodes on a substrate. CONSTITUTION:A film is printed using a platinum organic compound paste between platinum glazed electrodes 2 on a rectangular ceramic (dielectric) substrate 1 principally comprising alumina having size substantially equal to that of a rectangular chip resistor for surface mounting. The film is then fired to form a resistor 3 having relatively high resistance. Furthermore, cuts 7 are made in the resistor 3 in order to adjust the resistance by laser trimming. This structure increases the resistance by elongating the effective circuit length of the resistor 3 and allows highly accurate trimming of resistance over a wide range.
