Title:
TEMPERATURE OR PRESSURE SENSOR WITH FLOAT OR BALLOON
Document Type and Number:
Japanese Patent JPH03296629
Kind Code:
A
Abstract:
PURPOSE:To enable remote measurement of a temperature or a pressure in a liquid by attaching a float or balloon to a sensor. CONSTITUTION:A sensor 22 for measuring temperature is integrated with a float 23 and the float 23, for example, has a required coating of an acid- resisting, solvent-resisting agent or the like applied on the outer circumference of a foamed resin 24. With such an arrangement, the sensor 22 floats near the surface of various liquids and can measure temperatures at points near the liquid surface. The balloon 34 is filled with a lighter gas according to a density of a gas to be measured as compared therewith. For example, when the gas to be measured in temperature is air, He is filled or when it is a gas heavier than air, for example, chlorine gas, air is done. Moreover, a ferromagnetic body or a magnet 26 is provided at a proper point of the balloon 34 and a position of the sensor 22 is controlled with the magnet 26 from outside a container filled with the gas.
