Title:
PRESSURE DETECTOR ADJUSTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/142925
Kind Code:
A1
Abstract:
Provided is a pressure detector adjusting device capable of arbitrarily adjusting an initial position of a membrane member. This adjusting device of a pressure detector S is provided with a control unit E which successively executes a first step of bringing a first zone K1 to a prescribed adjusted pressure by driving a pump D while closing the first zone K1 by closing a solenoid valve B, and a second step of releasing the closure of the solenoid valve B and closing a gas phase portion S2, the first zone K1, and a second zone K2, and an adjusted pressure acquiring unit N which acquires the adjusted pressure in the first step on the basis of a relationship between the pressure and volume in the first zone K1 during the first step, and the pressure and volume in the gas phase portion S2, the first zone K1, and the second zone K2 during the second step, wherein the control unit E drives the pump D in such a way as to achieve the adjusted pressure acquired by the adjusted pressure acquiring unit N, as the first step, and then executes the second step to set a membrane member M to a position corresponding to the adjusted pressure.
