A method and apparatus for detecting and locating a quench zone (13) in a superconducting coil (11) is provided. A sensor (5) is positioned adjacent to and in heat transfer communication with the superconducting coil (11) along the entire length of the superconducting coil (11).

An improved control device and method is usable with flexible heating wire having a conductive core with a Negative Temperature Coefficient (NTC) layer and a helically wound heater conductor within an insulative outer sheath. The conductive core is coupled to a control circuit, a phase shift relative to the AC power supply being indicative of the temperature of the wire. The nonlinear nature of the NTC layer enhances the detection of local hot spots anywhere along the length of the wire. Precise temperature measurement is achieved by measuring the time differences between two zero crossings and the power to the heater compensates for abnormal use such as bunching of the heater wire. The control of the heater wire is particularly suitable for use with appliances such as heating pads and electric blankets.

Optical time-domain reflectometry can be used to sense respective values of a physical parameter, such as temperature, at different locations along an optical fibre (2). Prior broad spectrum methods call for special correction techniques to account for differential attenuation. Improvements in accuracy can be obtained in relation to prior art methods, without the use of significantly more complicated signal processing circuitry, by ensuring that back-scattered optical radiation used to produce output signals indicative of the values being sensed is restricted to a preselected single spectral line resulting from inelastic scattering in the fibre, for example one of the Anti-Stokes Raman lines, or to two mutually adjacent such lines.
