Title: Measuring apparatus
Inventor: SAKAI HIROMI
IPC: G01M3/26
Filed: 2000-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a measuring apparatus in which a measurement accuracy is improved at low costs and can be maintained easily in a pressure drop type leakage measurement. SOLUTION: A pressure controller 100 as a member to be measured is sunk in a temperature-controlled dry solvent. The measurement accuracy can be improved because no temperature change is present in the periphery of the pressure controller 100. Since the need of setting the measuring apparatus inside an air conditioning chamber is eliminated and a temperature in a room where the measuring apparatus 1 is set can be controlled roughly, a manufacturing cost and an operating cost for the measuring apparatus 1 can be reduced. The dry solvent including the air discharged from an air bleed tank 30 is supplied and transferred to a measurement tank 70. Therefore, an apparatus for controlling a temperature of the dry solvent stored in the measurement tank 70 is not required. The measurement accuracy can be thus improved by the simple constitution at low costs.
