Abstract: Provided is a pressure detection device that can suppress variation in the pressure detection characteristics of a pressure detection unit from occurring due to individual differences in the shape of flow passage units, variation in work in mounting the flow passage unit on the pressure detection unit, or the like. The pressure detection device including: a pressure detection unit; a flow passage unit; and a mounting unit configured to removably mount the flow passage unit on the pressure detection unit. The pressure detection unit has a pressure detecting diaphragm and a sensor rod arranged at the center part of a first surface of the pressure detecting diaphragm. The flow passage unit has a flow passage diaphragm, and a displacement of the flow passage diaphragm in contact with the top surface is transmitted to the pressure detecting diaphragm via the sensor rod.

Abstract: Provided is a pressure detection device including: a pressure detection unit configured to detect a pressure transmitted to a pressure detecting surface; a flow passage unit in which a pressure transmitting surface for transmitting a pressure of a fluid to the pressure detecting surface is formed; and a mounting unit for removably mounting the flow passage unit on the pressure detection unit. The pressure detection unit has a sensor unit having the pressure detecting surface, a holding unit configured to hold the sensor unit to be movable along an axis orthogonal to the pressure detecting surface, and an urging unit configured to generate urging force to urge the sensor unit toward the pressure transmitting surface. The mounting unit mounts the flow passage unit on the pressure detection unit with the pressure detecting surface being in contact with the pressure transmitting surface under urging force generated by the urging unit.

Abstract: There is provided a tube pump system including: a pair of roller units rotated around an axis line from a contact position to a separate position; a pair of drive units rotating the pair of roller units respectively; and a control unit controlling each of the pair of drive units. A pipe having flexibility is connected to an outflow-side end portion of the tube, and the pipe maintains a pressure of a liquid flowing through the inside of the pipe at a first predetermined pressure higher than an atmospheric pressure. The control unit controls each of the pair of drive units such that a pressure of the liquid in the tube closed due to a contact of the pair of roller units is increased to a second predetermined pressure when one of the pair of roller units passes the separate position.

Abstract: Provided is a pressure detection device, wherein a pressure detection unit includes: a pressure detecting diaphragm; a second connection portion; and four strain resistance portions. One of either a first connection portion or the second connection portion is formed of a magnet, and the other of either the first connection portion or the second connection portion is formed of a magnet or a magnetic body. The first connection portion and the second connection portion are arranged such that the first connection portion and the second connection portion are attracted by a magnetic force in a state where a flow passage unit is mounted on the pressure detection unit. The four strain resistance portions are attached to a region of a second surface of a pressure detecting diaphragm other than a center portion.
