PROTECTIVE TUBE DEVICE FOR PROTECTING A TEMPERATURE SENSOR AGAINST CONTACT WITH A FLUID

摘要

A protective tube device can protect a temperature sensor against contact with a fluid, and has a distal end containing the temperature sensor and has an outer wall provided for contact with the fluid, and a proximal end which is connected to the temperature sensor by electric lines and is intended for arrangement outside the fluid, wherein, on the outer wall of the distal end, an elastic membrane closes off a resultantly defined pressure transmission fluid reservoir in a fluid-impermeable manner, the pressure transmission fluid reservoir being connected fluidically by a fluid channel running within the protective tube device to a pressure sensor arranged in the proximal end.

1. A protective tube device for protecting a temperature sensor against contact with a fluid, the device comprising:
a distal end including the temperature sensor and including an outer wall configured to contact the fluid; and a proximal end, connected to the temperature sensor by one or more electric lines, suitable for arrangement outside the fluid, wherein, on the outer wall of the distal end, the outer wall includes an elastic membrane closes off a pressure transmission fluid reservoir in a fluid-impermeable manner, wherein the pressure transmission fluid reservoir is defined by the elastic membrane and the outer wall, wherein the pressure transmission fluid reservoir is connected fluidically by a fluid channel to a pressure sensor arranged in the proximal end, and wherein fluid channel the runs within the protective tube device.
