Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1 . 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. 2 . The pressure and temperature sensor according to claim 1 , wherein the pressure measurement body and the temperature measurement body are arranged on a side of the sensor body. 3 . The pressure and temperature sensor according to claim 1 , further comprising: bonding wires electrically connected to at least one of the pressure measurement body and the temperature measurement body. 4 . The pressure and temperature sensor according to claim 3 , wherein the buffering member is arranged more closely to the diaphragm than to the pressure measurement body and the temperature measurement body. 5 . The pressure and temperature sensor according to claim 3 , wherein a through hole is formed in the buffering member. 6 . The pressure and temperature sensor according to claim 5 , wherein the buffering member is formed so that an axis of the through hole is out of offset from the pressure measurement body and the temperature measurement body. 7 . The pressure and temperature sensor according to claim 1 , wherein the temperature measurement body is a resistance temperature detector. 8 . The pressure and temperature sensor according to claim 1 , wherein the pressure measurement body and the temperature measurement body are separate bodies. 9 . The pressure and temperature sensor according to claim 1 , wherein a measurement value of the pressure measurement body and a measurement value of the temperature measurement body are corrected with respect to each other. 10 . The pressure and temperature sensor according to claim 2 , further comprising: bonding wires electrically connected to at least one of the pressure measurement body and the temperature measurement body. 11 . The pressure and temperature sensor according to claim 10 , wherein the buffering member is arranged more closely to the diaphragm than to the pressure measurement body and the temperature measurement body. 12 . The pressure and temperature sensor according to claim 10 , wherein a through hole is formed in the buffering member. 13 . The pressure and temperature sensor according to claim 12 , wherein the buffering member is formed so that an axis of the through hole is out of offset from the pressure measurement body and the temperature measurement body. 14 . The pressure and temperature sensor according to claim 4 , wherein a through hole is formed in the buffering member. 15 . The pressure and temperature sensor according to claim 14 , wherein the buffering member is formed so that an axis of the through hole is out of offset from the pressure measurement body and the temperature measurement body. 16 . The pressure and temperature sensor according to claim 2 , wherein the temperature measurement body is a resistance temperature detector. 17 . The pressure and temperature sensor according to claim 2 , wherein the pressure measurement body and the temperature measurement body are separate bodies. 18 . The pressure and temperature sensor according to claim 2 , wherein a measurement value of the pressure measurement body and a measurement value of the temperature measurement body are corrected with respect to each other. 19 . The pressure and temperature sensor according to claim 3 , wherein the temperature measurement body is a resistance temperature detector. 20 . The pressure and temperature sensor according to claim 3 , wherein the pressure measurement body and the temperature measurement body are separate bodies. 21 . 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; and a temperature measurement body disposed in the accommodation space, wherein a measurement value of the pressure measurement body and a measurement value of the temperature measurement body are corrected with respect to each other.
