<p>PROBLEM TO BE SOLVED: To provide a pressure measurement apparatus which is useful for various kinds of constitutent devices of an apparatus for treating a waste plastic and for pipings between the various kinds of the constitutent devices and which are usable in a pressure measurement object part in which a hydrogen chloride- rich gas or an oil vapor can exist and an apparatus for treating a waste plastic, equipped with the pressure measurement apparatus. SOLUTION: This apparatus 1 for treating a waste plastic is equipped with the pressure measurement apparatus 20. Pressure detection parts 21 and 71 of the pressure measurement apparatus 20 are arranged at pressure measurement object parts 13n and 63n. Pressure measurement main body parts 24 and 74 are connected to the pressure detection parts 21 and 71. The pressure measurement object parts 13n and 63n are provided with inert gas induction parts 25 and 75 with which an inert gas is introduced into the pressure measurement object parts 13n and 63n and a gas which can exist in the pressure measurement object parts except the inert gas is prevented from coming into contact with the pressure detection parts 21 and 71.</p> |
