In a prior-art nail puncture test, it has been difficult to measure the temperature at a short-circuiting portion, which is closely related to the scale of an accident which occurs. As a solution, A nail puncture test device having a temperature measurement function, a sheath thermocouple, and a fixing portion 6 of the sheath thermocouple, wherein a bottomed hole through which the sheath thermocouple is inserted is bored in the axial direction from a head portion to the vicinity of the distal end at the center part of the outer frame, and the sheath thermocouple is fixed to the outer frame by the fixing portion 6 in a state where the sheath thermocouple is inserted into the bottomed hole and the distal end thereof having a temperature measurement point is in contact with the bottom of the hole is provided.

Abrégé

In a conventional nail puncture test, a temperature sensor such as a thermocouple is fixed to a battery to be tested in many cases in order to measure a heating value at the time of short circuit; and since, when the sensor is installed in the battery to be tested, the sensor itself may causes short-circuiting or the internal structure of the battery to be tested changes, the installation position of the temperature sensor is limited to the surface of the battery and thereby it is difficult to measure the temperature of a short-circuiting portion which has a close relationship with the scale of an accident that occurs. Nail puncture test equipment having a temperature measurement function comprises an outer frame (3) consisting of a high-hardness metal or ceramic and having the external shape of a nail, a sheath thermocouple (4), and a portion (6) for affixing the sheath thermocouple (4), wherein a bottomed hole (5), into which the sheath thermocouple (4) is inserted, is bored in the axial direction into the central part of the outer frame (3), having the external shape of a nail, from the head to the vicinity of the distal end of the frame, and, in a state where the sheath thermocouple (4) is inserted into the bottomed hole (5) and the distal end having a temperature measuring point is touching the bottom of the hole, the sheath thermocouple (4) is fixed to the outer frame (3) by means of the portion (6) for affixing.

Provided is a flange-mounting, screw-mounting or weld-attaching protective tube of a thermometer wherein corrosion of the protective tube and detachment of an anti-vibration band are prevented by eliminating the gap between the anti-vibration band and the surface of the protective tube, and the anti-vibration band can be formed conveniently. The protective tube of a thermometer comprises a tubular portion (2), and one or a plurality of ribs (3), i.e. anti-vibration bands, formed spirally on the outer wall of the body of the tubular portion (2), characterized in that the ribs (3) are formed by cutting the outer wall of the body of the tubular portion, and the protective tube has such a shape as being fixed to piping by flange-mounting, screw-mounting or weld-attaching.

This aims to provide a thermocouple of a quick response, which does not receive a mechanical damage such as a fold or bend even if it is used in a high-speed fluid. A quick-response thermocouple for a high-speed fluid is constituted such that a sheathed thermocouple of a small external diameter, in which a plus-side thermocouple filament and a minus-side thermocouple filament are contained in a metal sheath while interposing powder of an inorganic insulating material and in which the plus-side thermocouple filament and the minus-side thermocouple filament are joined to each other at their tips to form a temperature measuring point, is so inserted into a protective tube of a large external diameter as to expose its tip. The exposed portion of the sheathed thermocouple from the protective tube is inserted into a protective cylinder including a plurality of through windows and a bottom cover having a hole, through which the sheathed thermocouple is inserted, in its tip side, so that the tip of the sheathed thermocouple is shortly exposed from the protective cylinder bottom cover, and so that the protective cylinder bottom cover and the sheathed thermocouple, and the protective cylinder and the lower portion of the protective tube are welded to each other.

A sheath type measuring instrument can be mounted in place easily and smoothly without the need for boring holes in an outer wall and an inner wall with high positional accuracy and also for a complex process, even if a barrel is to be fixed to the outer wall while a tip end of a sheath is being inserted in a sheath insertion hole bored in an inner wall. The sheath type measuring instrument has a sheath having a tip end for being brought closely to or into contact with a measurand for measuring a physical property of the measurand, and a barrel holding a proximal portion of the sheath for movement in a direction perpendicular to an axis of the sheath.
