    摘要： A cylinder internal pressure sensor includes: a housing; a diaphragm having flexibility and being joined to one end of the housing; a sensor element configured to change an output signal according to deformation of the diaphragm; and an opposed member housed inside the housing so as to face the diaphragm. The opposed member defines a housing room between the diaphragm and the opposed member, and includes: a cylindrical tube part being a layered structure with an inner tube and an outer tube; and a seal part provided inside the tube part. The sensor element is fixed to the seal part. The tube part is provided with a spring rate reducing portion that is provided between the diaphragm and a position where the inner tube and the outer tube are joined together.

    摘要： The invention refers to a pressure-measuring device for converting a mechanical or hydraulic pressurization in a measuring signal and for forwarding the measuring signal to a remote evaluation unit. The invention distinguishes by a fastening device (1) for fastening the pressure-measuring device to a machine housing of a motor or a pump, a transmitter head (4) which is arranged on a measuring device head (3) of the pressure measuring device and which is to be connected to a light source via a first optical fiber (25), a receiver head (5) which is arranged on the measuring device head (3) of the pressure measuring device and which is arranged opposite to the transmitter head (4) to receive the light emitted by the transmitter head (4) via a light path in the measuring device head (3) and to be connected to the evaluation unit via a second optical fiber (26), and a measuring element (14), which in case of a mechanical or hydraulic pressure is displaceable on the measuring device head (3) into the light path between the transmitter head (4) and the receiver head (5).

    摘要： An apparatus for measuring temperature comprises a housing and an actuator pressure sealed to the housing and having a shaft. The actuator is configured to be in pressure communication with a volume of gas or liquid. Upon a change in pressure, the actuator is displaced at least partially in the axial direction. A sensor detects axial displacement of a magnetically encoded target upon the change in pressure in the volume. A device for measuring pressure and temperature in an engine cylinder comprises a valve in pressure communication with an engine cylinder. The valve stem has a magnetic coding located adjacent a sensor. Axial displacement of the stem under cylinder pressure and temperature changes are detected.
