Method and apparatus for measuring vibrations
First Claim
1. A method of measuring the vibration of a duct disposed in a thermal enclosure in which duct there flows at least one fluid, in which method use is made of a vibration sensor disposed inside said thermal enclosure, said sensor being secured to a sensor support, said sensor support being pressed against said duct to enable and facilitate transmission of vibration by conduction from said duct to said sensor support, and from said sensor support to said sensor, at least the portion of the sensor support adjacent the sensor being within the thermal enclosure, and said duct and said portion of the sensor support being exposed to heat provided within said thermal enclosure, said sensor being cooled by a cooling fluid flowing within said sensor support.

- 1. A method of measuring the vibration of a duct disposed in a thermal enclosure in which duct there flows at least one fluid, in which method use is made of a vibration sensor disposed inside said thermal enclosure, said sensor being secured to a sensor support, said sensor support being pressed against said duct to enable and facilitate transmission of vibration by conduction from said duct to said sensor support, and from said sensor support to said sensor, at least the portion of the sensor support adjacent the sensor being within the thermal enclosure, and said duct and said portion of the sensor support being exposed to heat provided within said thermal enclosure, said sensor being cooled by a cooling fluid flowing within said sensor support.
- 5. A physical or chemical treatment method in which one or more substances are caused to flow inside a duct disposed in a thermal enclosure, and in which enclosure said duct is subjected to vibration, wherein vibrations of the duct are measured by a vibration sensor disposed inside said enclosure, said sensor being secured to a sensor support disposed at least partially within said enclosure, and said sensor support being pressed against said duct to enable and facilitate transmission of vibration by conduction from said duct to at least a portion of said sensor support, and from said sensor support to said sensor, said sensor being cooled by a cooling fluid flowing within said sensor support.
-
8. Apparatus for physically or chemically treating one or more substances inside a duct, the apparatus comprising:
-
said duct disposed in a thermal enclosure; and a generator for establishing vibrations of said duct, the apparatus including a duct vibration sensor disposed inside the enclosure, cooling means for cooling said sensor, wherein said cooling means comprises at least one cooling circuit for cooling said sensor by means of a fluid, the apparatus further comprising a sensor support for said sensor and containing the cooling means for cooling said sensor, at least the portion of the sensor support adjacent the sensor being positioned within said enclosure, and thrust-generating means exerting a force on said sensor support in the direction of said duct.
