Abstract
Disclosed is a pressure and temperature sensor capable of precisely measuring a pressure. A sensor body, a diaphragm defining an accommodation space together with the sensor body, and a transmission substance charged in the accommodation space are provided, and a pressure measurement body and a temperature measurement body which is a separate body from the pressure measurement body are disposed in the accommodation space.
Claims21
A pressure and temperature sensor comprising:
- a sensor body;
- a diaphragm defining an accommodation space together with the sensor body;
- a transmission substance charged in the accommodation space;
- a pressure measurement body disposed in the accommodation space;
- a temperature measurement body disposed in the accommodation space;
- a buffering member having a base portion which is disposed between the diaphragm and the pressure measurement body and between the diaphragm and the temperature measurement body in the accommodation space and which is configured to buffer the transmission substance;
- and
- a through flow passage which has an opening portion opened toward the base portion of the buffering member, and which is configured to the accommodation space through the opening portion and to be closed after the transmission substance is charged in the accommodation space through the through flow passage,
- wherein an axial dimension between the buffering member in the accommodation space and the opening portion of the through flow passage is shorter than a thickness of the base portion of the buffering member.
