Abstract
The present invention relates to a measurement device for fixing to a pipe or a vessel containing a fluid, the device including a pressure sensor surrounded by a wall. The device includes a coating adhering to said wall and suitable for isolating the fluid sensor.
Claims30
A measurement device for fixing on one of a pipe and a vessel containing a fluid, the device comprising
- a pressure sensor,
- a wall surrounding the pressure sensor,
- a coating adhering to said wall and configured for isolating the sensor from the fluid, wherein the coating adheres sufficiently to the wall of the device to enable it to be used without the wall pressing against a step in a hole in the pipe or the vessel in which the device is inserted.
A measurement device for fixing on one of a pipe and a vessel containing a fluid, the device comprising:
- a pressure sensor,
- a wall surrounding the pressure sensor,
- an adhesive filling a clearance between the pressure sensor and the wall surrounding the pressure sensor, and
- a coating configured for isolating the sensor from the fluid, wherein the coating adheres sufficiently to the wall of the device to enable it to be used without the wall pressing against a step in a hole in the pipe or the vessel in which the device is inserted.
1 more element
A method of measuring the temperature of a fluid, the method comprising:
- measuring the temperature of the fluid in a pipe or a vessel containing said fluid by fixing on a pipe or a vessel containing the fluid a measurement device comprising a ceramic diaphragm pressure sensor, a wall surrounding the pressure sensor, and a coating adhering to the wall and configured for isolating the sensor from the fluid, wherein the coating adheres sufficiently to the wall of the device to enable it to be used without the wall pressing against a step in a hole in the pipe or the vessel in which the device is inserted, the measurement device further comprising at least one temperature sensor close to the pressure sensor, the fluid temperature being measured with said at least one temperature sensor.
