Abstract: Provided is a temperature sensor used in a molding machine, comprising a cylindrical fiber probe into which an optical fiber is inserted; a window support part formed in a cylindrical shape and into which at least a part of the fiber probe is inserted; a protective window disposed on a tip end side of the fiber probe while being at least partially inserted into the window support part; and a sleeve member formed in an annular shape, and having an inner circumferential surface in contact with an outer circumferential surface of the protective window and an outer circumferential surface in contact with an inner circumferential surface of the window support part.

Abstract: A capacitive pressure sensor (1) using mutual capacitance type is provided. The capacitive pressure sensor (1) comprises a dielectric layer (2), a ground electrode (3), transmission electrodes (4), reception electrodes (5) and a controller (6). The transmission electrodes and reception electrodes have a matrix structure (FIG. 3). An electric field is generated between the transmission electrodes and the reception electrodes by the controller. When the dielectric layer is deformed by a pressure applied to the ground electrode, a capacitance of the dielectric layer changes. The controller detects the unit detection area (10) where the capacitance changes and the pressure corresponding to the change in the capacitance.
