PROBLEM TO BE SOLVED: To provide a connection structure for a pressure measurement probe, which is enabled to measure a pressure precisely, when the internal pressure of a measurement system is prevented from rising higher than an atmospheric pressure by the connection of a probe, in the case where a pressure is inexpensively measured with respect to the atmospheric pressure without providing a pressure adjustment mechanism for adjusting the pressure inside of the measurement system.SOLUTION: A cylindrical member 20 of a probe 1 comprises a connection part 21 connected to a connector, and a communication hole 24. The probe 1 is equipped with a switching member 40 for switching an atmosphere open state in which the communication hole 24 is opened into the atmosphere, and a non-open state in which the communication hole 24 is in an unopened state.SELECTED DRAWING: Figure 15 |
