Abstract

The invention provides a sputtering film pressure transmitter, which belongs to the technical field of sensors, and comprises from top to bottom: an upper shell assembly, a circuit board assembly and a lower shell assembly, and the upper shell assembly and the circuit board assembly pass through the first A pin forms an electrical connection, the lower shell component and the circuit board component form an electrical connection through a gold wire, and the upper shell component and the lower shell component are fixed by welding. A sputtering film pressure transmitter provided by the present invention realizes anti-reverse connection and suppression of interference signals such as surge, pulse group, conduction, and radiation through the power supply protection circuit board. In addition, the power supply protection in the circuit board assembly The circuit board, the signal processing circuit board and the signal transfer circuit board are all fixed by a purely mechanical structure, which is different from the colloidal fixing method in the prior art, avoiding the high temperature melting of the colloid, affecting the reliability of the transmitter, and improving the reliability of the transmitter. Transmitter use stability.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a transmitter, in particular to a sputtering film pressure transmitter. Background technique [0002] Pressure transmitter is the most commonly used sensor in industrial practice, suitable for industrial self-control environment, used to measure the pressure of liquid, gas or steam, etc. The pressure transmitter is mainly composed of a load cell sensor, a module circuit, a display head, a watch case and connectors, etc. It can convert the gas, liquid and other pressure signals received by the load cell sensor into a standard current and voltage signal. [0003] Chinese patent (CN210400699U) discloses a pressure transmitter, a pressure detection device and construction machinery. The pressure transmitter includes an electrical connector and a pressure nozzle that are connected to each other. For the pressure sensitive element detecting the pressure in the pressure detection channel...
