Why do pressure transmitters need aging tests?

Project Overview

A pressure transmitter is a device that converts pressure into pneumatic signals or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement, indication, and process regulation.

Flow instrument manufacturer Supmea Measurement and Control stated that the pressure transmitter must undergo an aging test before leaving the factory. The principle of the aging test is: the semiconductor devices of most instrument products are at risk of early failure or failure, which will shorten their chip life. The aging test can be performed at this critical early stage to determine the reliability of the component. Power-on aging of pressure transmitters is a necessary procedure for manufacturers in the production process. It is a product testing and quality control process to better ensure the stability and reliability of pressure transmitter products. In addition to the aging test, the pressure transmitter must also undergo detailed inspections on the product pressure type and pressure value, product accuracy, product stability, and product installation structure before leaving the factory to ensure product quality.

Supmea series pressure transmitters have undergone a series of inspection and testing procedures before leaving the factory. Different from conventional pressure transmitters, the HSYB series pressure transmitter uses a piezoresistive isolation diaphragm oil-filled core to monitor the pressure signal. It is processed by a dedicated integrated circuit and outputs a unified standard signal; it uses temperature compensation technology for the pressure sensitive element. It not only ensures the measurement accuracy of the pressure sensor, but also provides prerequisites for its continuous normal operation in harsh environments, ensuring the reliable performance and quality of the product. At present, HSYB series pressure transmitters are widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, petrochemicals, oil wells, electric power, pipelines and many other industries.

In summary, no matter what kind of product, corresponding inspections should be done before leaving the factory. This is not only a guarantee of product quality, but also the responsibility of manufacturers towards users. Questions about flow instruments such as pressure transmitters, vortex flowmeters, magnetic inductive flowmeters, ultrasonic flowmeters, balanced orifice flowmeters, turbine flowmeters, flow totalizers, steam prepayment systems, smart heating network management systems, etc. are welcome at any time.
