A retro-reflective sensor coating arrangement comprises a base layer of luminescent sensor material and an outer layer of optical bodies, such a spheres.

Sensor coating

A thermocouple connector has a first member and a second member which couples to the first member. The first member carries two first terminals for electrically joining to the respective ends of a pair of thermocouple wires. The second member carries two corresponding second terminals for electrically joining to the respective ends of a pair of thermocouple extension wires. Each first terminal contacts a respective second terminal when the first and second members are coupled.

An apparatus () for measuring temperature using luminescence thermometry, comprising: a photon emitter () for providing photons () of at least a first frequency; photoluminescent material () that produces photons () of at least a second frequency in response to the incidence of photons () of the first frequency; one or more photon receivers (); and an optically dispersive element () for directing photons () of at least a second frequency produced by the photoluminescent material () into the photon receiver(s).

Apparatus for measuring temperature using luminescence thermometry

A method of measuring temperature of a component capable of emitting thermal radiation and reflecting background radiation having the steps of: providing a pyrometer for measuring the radiation from the component, characterised by coating a part of the component with a first emissivity coating and a part of the component with a different and second emissivity coating, each with known emissivities Eand Erespectively, recording a first radiation measurement from the first emissivity coating Rand a second radiation measurement from the second emissivity coating R, then calculating the true radiation Rfrom the component from the equationand relate the Rvalue to the true component temperature by calibration of the pyrometer.
