When screwed into 26, the temperature / pressure display section 6 also turns, so when screwed in sufficiently,
Not necessarily the vertical direction 2 of the scale plate 4 of the temperature / pressure display unit 6.
4 does not always face up and down in the attached state, but may tilt rightward or leftward. Therefore, in order to mount the scale plate 4 so that the direction of the scale plate 4 is in the correct direction, the sealing tape to be wound around the threaded portion 25 serving as the measured object mounting portion 14 may be wound thickly or thinly to adjust the screwing. I am forced to do troublesome work.

る。In order to eliminate such troublesome work, the temperature / pressure display portion 6 may be mounted without rotation, and for that purpose, a union screw may be adopted as the screw portion 25 serving as the object mounting portion 14. Conceivably, in this case,
The outer diameter of the threaded portion formed on the outer circumference of the union screw is inevitably large. Usually, the inner diameter of the screw hole 26 of the object to be measured 10 is often standardized. Therefore, even if a union screw is adopted as the threaded portion 25 that becomes the conventional object to be measured mounting portion 14, it is measured. The water height thermometer cannot be attached to the object to be measured 10 because it cannot be screwed into the screw hole 26 of the object 10. Therefore, this can be solved by reducing the diameter of the connecting cylindrical body 9 forming the measured object attaching portion 14 on the outer peripheral surface, but since the connecting cylindrical body 9 has the hole 25 which becomes the pressure transmission passage 13, the corresponding cylinder is formed. As long as the wall is required, the connecting cylinder 9 cannot have a small diameter as long as it has such a configuration, and the threaded portion 25 that becomes the measured object mounting portion 14 of the conventional water thermometer is used.
It is considered impossible to adopt a union screw as.

ある。The present invention is based on the difference in diameter between the spirally wound bametal and the rotating shaft that rotates due to expansion and contraction in the direction of rotation that occurs when the spirally wound bametal is temperature-sensitive and that moves the temperature pointer in the temperature / pressure display section. It was completed by paying attention to the use of the space in the temperature-sensing cylinder that arises as an area where the pressure transmission passage is provided, and by making it possible to reduce the diameter of the connecting cylinder.

に取付けることができる。As described above, in the pressure transmission passage of the water thermometer according to the present invention, one end of the pressure transmission passage is opened to the outside of the temperature sensitive cylinder, and the temperature sensitive cylinder is hermetically sealed by the seal portion. Since the intermediate portion penetrates into the temperature sensitive cylinder and the connecting cylinder body and enters the temperature / pressure indicating portion, the other end is formed by a pressure transmission pipe connected to the Bourdon tube for communication. It is possible to reduce the diameter of the connecting cylinder, and it is possible to adopt a union screw as a screw portion that is screwed into the screw hole of the measured object that becomes the measured object mounting portion on the outer periphery of the connected cylindrical body, and A flange portion is formed on the outer periphery of the end portion of the connecting cylinder as an object mounting portion, and the end portion of the connecting cylinder is rotatably and axially movable so that the end can abut on the flange portion. A union screw having a male thread portion on the outer peripheral surface to be mated, and a female screw threaded to the union screw on the inner peripheral surface. The union is composed of a threaded portion and a small-diameter step portion that can come into contact with the flange portion, and an outer peripheral surface having a male thread portion that is screwed into a threaded hole of the measured object. Even if the screw is turned, the connecting cylinder does not turn, and the water thermometer is attached to the DUT by first screwing the DUT mounting screw into the screw hole of the DUT, and then With the scale plate of the display unit oriented in the correct direction, screw the union screw into the screw for mounting the DUT, and connect the flange of the connecting cylinder to the end of the union screw and the small diameter of the screw for mounting the DUT. By sandwiching between the stepped portions, the scale plate of the water thermometer can be correctly oriented and easily and surely attached to the object to be measured.
