Tyco Thermal Controls has introduced the new Raychem VPL Power-Limiting Heating Cable, developed to operate at higher exposure temperatures and greater power output.
CapaciSense high temperature, clearance measurement systems can monitor gas turbine engines in operation using high bandwidth capacitive sensing systems.
They have been fitted into new engines for over three years now and have proven highly successful at delivering accurate data on compressor and turbine blade-tip clearance measurements, rotor shaft and disc displacement.
The 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 2550degF (1400degC).
Using advanced electronic processing, CapaciSense will output real-time, high accuracy blade-clearance proximity information and can be configured to assist with engine condition monitoring, blade vibration and adaptive clearance control.
The CapaciSense systems comprise world leading probes - including patented sprayed ceramics and captive components.
Used for many years solely for engine test and development, tip clearance systems are now mature technologies and are being quickly adopted for condition monitoring and adaptive control of turbines.
Manufactured in accordance with ISO9001 2000, the engine-mounted electronics package, carries FM and ATEX approval for use in hazardous areas.
Tyco Thermal Controls can demonstrate a real expertise in the field of sensors used in power generation operations.
Its Pyrotenax brand has been a leading name in sensors for steam turbines, boilers and nuclear reactors for some 60 years.
In the gas turbine industry, CapaciSense has now accumulated over ten years experience working with development teams to generate meaningful clearance results and now boasts world leading probes that are proven to work.
In addition to the design, manufacture and supply of measurement systems, the Company offers total technical support including sensor advice and a full calibration service.
