1,186,980. Temperature sensitive devices. J.E. LINDBERG. Dec. 12, 1968 [Feb. 13, 1968], No. 59161/68. Heading G1D. A temperature detection device comprises a wire-like sensor 11 formed as a helix and a wire-like support member 12 formed as a helix of the same pitch and handing, the two being intertwined so that the member 12 supports the sensor 11 throughout its length. The support member is preferably of larger diameter than the sensor 11 and may be coated with electrical insulation material and may be in the form of a tube with a return wire from the remote end of the sensor passing therethrough if this is necessary. The sensor 11 may be hollow and enclose gas to sense the average temperature along its length or may contain a gas-emitting material inside to sense discrete peak temperatures a combination of the two. Also the sensor may be wound itself with a much smaller pitch helix of small wire 40 and as a further protection the member 12 and sensor 11 may be coated with molybdenum disulphide as an anti-friction lubricant. |
