Pressure transmitter is a device that converts pressure into pneumatic signal or electric signal for control and remote transmission. It can convert the physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals to supply secondary instruments such as alarm, recorder and regulator for measurement, indication and process adjustment.

Flow meter manufacturers said that the pressure transmitter 4-20ma must be aging tested before leaving the factory. The principle of burn-in testing is that semiconductor devices in most instrumentation products are at risk of early failure or failure, which can shorten the life of their chips, and burn-in testing can be performed at this critical early stage to determine the reliability of the components. The aging of the china pressure transmitter is a necessary procedure in the production process of the manufacturer, and it is the process of testing and quality control of the product to better ensure the stability and reliability of the pressure transmitter product. In addition to the aging test, the pressure transmitter should also conduct a detailed inspection of the product pressure type and pressure value, product accuracy, product stability and product installation structure before leaving the factory to ensure product quality.

In summary, no matter what kind of product, the corresponding inspection work should be done before it leaves the factory. This is not only the guarantee of product quality, but also the responsibility of the manufacturer to the user.
