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.
Stainless steel pressure gauges are widely used in petroleum, chemical, chemical fiber, metallurgy, power stations and other industrial sectors. There are processes with high corrosion resistance and vibration resistance requirements to measure the pressure of various fluid media. Therefore, it is made of stainless steel pressure gauges.
In the case of static test (or slow change), the maximum value of the measured pressure shall be two-thirds of the full scale value of the pressure gauge; in the case of pulsating (fluctuating) pressure, the maximum value of the measured pressure shall be selected from the pressure gauge One-half of the full-scale value.
Stainless steel pressure gauge is composed of pressure guiding system (including joint, spring tube, current limiting screw, etc.), gear transmission mechanism, number display device (pointer and dial) and shell (including watch case, watch cover, watch glass, etc.).
If the Rosemount transmitter is directly connected with a thermocouple or resistance temperature sensor, it may cause some problems at the input end of the host system of the instrument, thereby affecting the measurement effect of the transmitter. To solve this problem, we can add a temperature transmitter near the sensor.
Rotameter flow meter are the most commonly used flow meters in industry and laboratories. It has the characteristics of simple structure, intuitive, small pressure loss, convenient maintenance and so on. The rotameter float measures the fluid flow according to the throttling principle, but it changes the flow area of the fluid to keep the differential pressure above and below the rotor constant.
For the diversity of industrial flow measurement instrumentation equipment, we can choose to use different instrumentation equipment due to different application environments when using industrial instruments. So what is the difference between a turbine flow meter and a vortex flow meter?
