Capacitance sensors for non contact measurement Capacitive sensors were first developed to measure the clearance between the tip of the blades and the casing of turbo engines. The turbo engine output is directly related to this clearance which must be as small as possible, to give maximum output efficiency, however in no circumstances must the blades touch the engine casing. Most capacitive sensors applications have been mainly used for measurement in aircraft engines however the same types of measurement apply to industrial gas turbines: • Compressor control • Turbine control • Development measurement •...

up to 1400°c without cooling system Expertise In partnership with the main international turbine manufacturers, THERMOCOAX offers capacitive sensors which can withstand very high temperatures and are adapted to two different technologies: • Triaxial up to 1100°C • Pseudo-triaxial up to 1100°C and1400°C To work with our customers requirements for higher temperature ranges, THERMOCOAX solutions were developed with: • ceramic / metal brazing • ceramic / platinum brazing • special designs to avoid the disintegration of the probe in the turbine • triaxial mineral insulated cable with high level of...
