A seal provided in a pressure-balanced cylinder. Amendment February 6, 1982 The scope of claims for utility model registration is amended as follows. -O Utility Model Registration Claims (1) For scale and detection, one end of the cylinder housing the Rad has a connecting hole, and through the connecting hole, the cylinder is provided inside the ladder and outside the cylinder so that it can be easily deformed. A measuring device characterized in that two pressure-equalizing cavities are connected to each other. (2) The measuring device according to claim 1, which is a registered utility model, wherein an incompressible fluid is sealed in the cylinder and the pressure equalization cavity. The brief description of the drawing has been amended as follows. Correcting “torso” on page 8, line B of the specification as “dong” = Correcting “torso” on page 8, line 9 of the specification box as “dong” = “” on page 8, line 10 of the specification Correct "torso" to "dong". "Torso" on page 8, line 11 of the specification is corrected to "dong." The word "torso" on page 8, line 13 of the specification is corrected to "dong."

Claims

[Scope of utility model registration request]

(1) The cylinder housing the scale and the detection head has a connecting hole at one end, through which the inside of the cylinder is connected to a pressure equilibrium cavity provided outside the cylinder that is easily deformable. - A measuring device characterized by:

(2) Claim 1 of the utility model registration, in which an incompressible fluid is sealed in the cylinder and the pressure equalization cavity. Measuring device as described.
