を特徴とする圧力変換器。 A piston having a large-diameter primary piston and a small-diameter secondary piston is slidably inserted into a barrel having a large-diameter primary liquid chamber and a small-diameter two-character liquid chamber, and the primary liquid chamber is slidably inserted into the barrel. A pressure transducer configured to reciprocate the primary piston with the primary liquid supplied to the chamber, thereby causing the secondary piston to reciprocate and send out the secondary liquid supplied to the secondary liquid chamber under increased pressure. An oil chamber communicating with the primary liquid chamber and the secondary liquid chamber is formed inside the secondary piston, and a small piston that is always biased toward the secondary liquid chamber is slidable in the oil chamber. In addition to fitting, a check valve that is always biased toward the primary liquid chamber side is provided in the middle of the guide hole that communicates the oil chamber and the primary liquid chamber, and the secondary piston is provided with a check valve that is always biased toward the primary liquid chamber side. A pressure transducer characterized by having a conduit hole communicating with an oil chamber.
