Abstract
PURPOSE: To obtain an explosion-proof detector which assures stable action with a low noise by optical detection of the specific frequency of the vibrator varying with the temperature with the pressured fluid of the measuring temperature jetting over the vibrator.
CONSTITUTION: As the fluid pressurized with a pump or the like reaches the specified temperature with the heat exchanger 3 maintained at the measuring temperature, it jets out over the vibrator 5 in turbulence from the nozzle larger than the critical Reynolds number. This enables the vibtator to vibtate at the frequency varying with the temperature of the fluid regardless of the fluid velocity. The vibration is detected with the light source 7, the light wave channel, lenses 8 and 9, and 11 and 10 and the light detector 12 and the frequency proportional to the temperature measured with the frequency measuring device 13. This arrangement dispensing with wire or the like assures stable temperature detection with a low noise and an explosion-proof property.
