BRIDGE ADAPTOR FOR CAPSULE TYPE HIGH TEMPERATURE STRAIN GAUGE AND CABLE CONNECTING STRUCTURE FOR CAPSULE TYPE HIGH TEMPERATURE STRAIN GAUGE

PROBLEM TO BE SOLVED: To provide a bridge adaptor which has a simple structure, can be easily installed in a sealed part, can reduce execution mandays for installation, and can prevent erroneous wiring effectively as well. SOLUTION: To a sensor unit 1, a metal-coated cable 2 is connected, and the metal-coated cable 2 is connected to a flexible cable 4 with the bridge adaptor 3 having a cable connecting function. In the metal-coated cable 2 as a heat-resisting cable, a signal wire is insulated from a metal coating by filling up the inside of a heat-resisting tubular metal coating with an inorganic insulator along with enclosing the signal wire inside the metal coating, like an MI cable. A pair of lead wire temperature compensating resistors different in polarity are arranged side by side in parallel and being inclined against the direction of a column made up of gauge temperature compensating resistors, bridge balance compensating resistors, and Wheatstone bridge forming resistors, to reduce the dimension of packaging in a crosswise direction of a bridge adaptor board.
