The switch mechanical characteristic tester is a newly designed special instrument for detecting the mechanical dynamic characteristics of high voltage circuit breakers. The instrument adopts high-tech technology and integrates computers, printers, measurement interface circuits, and operating power sources into one, and is a new special instrument for high-voltage circuit breaker detection. The instrument is equipped with two displacement sensors suitable for different distances and accuracy tests. The automatic identification system of the switch mechanical characteristic tester recognizes the selected sensors to complete the low oil, multi oil, sulfur hexafluoride, vacuum high voltage circuit breaker Ranging, speed measurement.
Installation instructions
1. The principle of the online density meter is a double flange differential pressure method based on static pressure. Because the measured liquid is sometimes not stationary, it is constantly circulating and agitating. Therefore, devices that use the static pressure principle to test density must overcome these effects. In places where direct measurement is not suitable, an auxiliary test tank should be added to allow the density meter to work in a place where the flow rate and fluctuation are small to ensure the stability of the density meter reading.
2. The specific installation drawing is designed and decided by the technical personnel on site according to the size of the purchased equipment.
3. For the testing of flowing liquids or liquids with large vibrations, an auxiliary measuring tank should be added in order to stabilize the measurement reading. When adjusting the flow rate of the liquid in the measuring tank, the field operator must take into account both the dynamic and the stability of the reading.
4. On-site installation of density timing must ensure that the two pressure repeaters are on the same vertical plane, otherwise measurement errors will occur.
5. Installation method of online density transmitter on the tank
6. The liquid to be measured on site must be kept within two measurement sensors.
7. The online density meter can theoretically measure the concentration according to different media, please use the user to convert the concentration result according to the site situation.
