Abstract: Disclosed are a signal processing assembly for a pressure sensor and a pressure sensor. The signal processing assembly for the pressure sensor includes a horizontal plate, a first flexible plate, a longitudinal plate, a second flexible plate and a first conductive connecting portion connected in sequence. The horizontal plate, the longitudinal plate and the first conductive connecting portion are provided in sequence from near to far; the first conductive connecting portion is electrically connected to the pressure measurement circuit, and the pressure measurement circuit is provided at a horizontal plane located at a distal side of the first conductive connecting portion, so as to well connect the signal processing circuit and the pressure measurement circuit.

Abstract: A pressure sensor includes a pressure port provided with a pressure channel extending longitudinally; a pressure sensitive head, wherein a longitudinal distal end of the pressure sensitive head is recessed inward to form a connection cylinder provided with a sensing cavity, and a longitudinal proximal end of the pressure sensitive head correspondingly formed with an elastic diaphragm; a terminal connector and a housing enclosed with the pressure port to form a mounting cavity; a mounting seat and a signal assembly provided in the mounting cavity; and a plurality of electrical connectors electrically connected to the signal assembly after passing through the terminal connector. One side surface of a longitudinal proximal end of the elastic diaphragm is provided with a pressure measurement circuit, and a proximal end of the connection cylinder is sealedly connected to the pressure port.

Abstract: A pressure measurement assembly includes a pressure connector provided with a pressure channel extending longitudinally and a pressure sensitive head. The longitudinal distal side of the pressure sensitive head is recessed inward to form a connecting tube with a sensing cavity facing the distal end, and the longitudinal proximal side of the pressure sensitive head is correspondingly formed with an elastic diaphragm. The longitudinal proximal side of the elastic diaphragm is provided with a pressure measurement circuit, and the proximal end of the connecting tube is sealed and connected to the pressure connector so that the proximal end of the pressure channel is in fluid communication with the sensing cavity. The proximal end of the connecting tube is welded to the pressure connector.

Abstract: A temperature-pressure sensor includes a shell, a pressure sensitive component provided in the shell and a temperature sensitive component provided in the lower cavity. The shell is provided with a fluid inlet. The pressure sensitive component includes a ceramic plate laterally extended. The temperature sensitive component includes a temperature sensor, and two connection ends of the temperature sensor are respectively electrically connected to the circuit board through an elastic connection body, a conductive pin and a conductor. The conductive pin is respectively correspondingly penetrated through two via holes opened on the ceramic plate, and a gap between the conductive pin and the corresponding via hole is sealed by a seal body made of glass material; and the fluid inlet is communicated with the lower cavity.
