Nuclear
In the early 1970's, Vibro-Meter diversified into the nuclear business, supplying piezoelectric transducers qualified for start-up, hot functional tests, and permanent monitoring of primary circuits. The systems designed for these applications were high reliability transducers (vibration and dynamic pressure transducers) with their associated remote charge converter and interface cables.
Since 1978, Vibro-Meter's nuclear systems have been used for many applications including start-up and HFT, loose parts monitoring, reactor internals vibration monitoring, fuel pin flow induced vibration, steam generator and in-core fuel flow induced vibration programs. Vibro-Meter supplies mainly high temperature qualified sensors.
Space
Launchers
Vibro-Meter's involvement in designing measuring systems for space applications began in 1987, thanks to the experience acquired in designing monitoring systems for aircraft engines and nuclear reactors. Vibro-Meter's instrumentation supported the development of the Vulcain and Vulcain 2 main engines of the Ariane 5 launcher.
Today, many Vibro-Meter systems are flight qualified for Ariane 5 and similar instrumentation is awaiting qualification on the second stage engine VINCI. We supply cryogenic accelerometers, dynamic pressure transducers, and high temperature sensors.
Our sensors measure:
- Displacement, relative and absolute vibration, rotational speed and dynamic pressure in liquid oxygen and hydrogen high pressure turbopumps.
- Shocks on pyrotechnic devices.
- Absolute vibration and dynamic pressure on engine gas generator and output nozzle
- Absolute vibration (modal analysis) for launcher structures.
High Reliability Microgravity and Satellites
A further step was taken in 1996 with the development under an ESA GSTP competitive contract of a High Resolution Standard Proximity Sensor (HRSPS). The HRSPS is intended to become the standard for space qualified high-resolution nano-measurement displacement/position measuring systems.
