ATEX oscillator and longer cables for tip clearance measurement systems
14 May 2009
Tyco Thermal Controls has introduced an ATEX certified oscillator which adds hazardous area capabilities to its 5 Series CapaciSense high temperature, tip clearance measurement systems for gas turbine engines. The oscillator enables energy limited outputs to the sensing probe and connection and disconnection functions to be performed within the hazardous area.
ATEX oscillator and longer cables for tip clearance measurement systems
When used in combination with Tyco Thermal Controls latest cable, probes up to 10 metres in length can be supported so the oscillator can be installed outside of the turbine compartment for easier access and thermal management, whilst the rack electronics can still be 100 metres away from the oscillators.
Capable of monitoring gas turbine engines in operation, CapaciSense capacitive sensors deliver real time data on compressor and turbine blade-tip clearance measurements, rotor shaft and disc displacement.
CapaciSense high temperature clearance measurement systems accurately monitor a wide range of clearances within modern gas turbine engines. These systems have a patented capacitive sensor design that can be used with AM or FM electronics and are capable of withstanding tip temperatures up to 1400C. Using advanced electronic processing, CapaciSense will output real-time, high accuracy, blade-clearance and blade deflection information and can be configured to assist with engine condition monitoring, blade vibration and rotodynamic measurements.
