With the advancement of instrument technology, differential pressure transmitters of various brands are developing in the direction of high precision and intelligence.
Differential pressure transmitter is the most commonly used weight transmitter in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.
The installation position of the differential pressure transmitter on the process pipeline is related to the measured medium.
Differential pressure transmitters are widely used in factories. In order to ensure their normal operation and accuracy, regular inspection and calibration are necessary. A method for on-site calibration without removing the pressure guiding tube is now introduced.
The selection of pressure and differential pressure transmitters is mainly based on the measured medium, temperature environment, accuracy level, installation and maintenance costs, etc. After determining the manufacturer and model of the transmitter used, determine the variable according to the use requirements. range of the transmitter.
The pressure transmitter amplifies the weak electrical signal collected by the pressure sensor in order to transfer or start the control element. Or a signal source that converts the non electric quantity input by the sensor into an electrical signal and amplifies it at the same time for remote measurement and control. Analog quantity can also be converted into digital quantity as required.
What pressure transmitter parameters do I need to provide when buying a pressure transmitter? In fact, it is very simple to buy a pressure transmitter that suits you. Just master and determine a few factors. Viscous liquids and mud will block the pressure port. Will solvents or corrosive substances damage the transmitter?
Rosemount working principle: when working, the diaphragm and filling fluid on the high and low pressure sides transfer the process pressure to the filling fluid, and then the filling fluid transfers the pressure to the sensor diaphragm of the sensor.
