Tips for using level transmitters
2011-11-23 11:32:15

送器 是目前使用非常广泛的仪表,对 投入式液位变送器 的维修和保养 是日常工作的必须。 The input type liquid level transmitter is a very widely used instrument. The repair and maintenance of the input type liquid level transmitter is a must for daily work.
投入式液位变送器 的维修和保养的前,我们先看看 投入式液位变送器 原理的介绍,根据压力原理来进行物位测量,测量探头承受的压力与水深成正比。 First of all, before we learn about the repair and maintenance of the input level transmitter , we first look at the introduction of the principle of the input level transmitter , perform level measurement according to the pressure principle, and measure the pressure and water depth on the probe. Directly proportional. Before formal operation, the secondary water meter's detection value must be corrected in accordance with the current level gauge or other effective reference value of the inland or outer river of the sluice to ensure the correctness of the sampling data.
   维护和保养:每个月清洗一次。 Submersible Level Transmitter Maintenance and Maintenance: Clean once a month. 投入式液位变送器 上附着的杂物( 比如水草,浮游生物等 ) 清除掉。 When cleaning, first open the screw cap of the submerged water level meter and carefully take out the liquid level gauge ; then remove the debris ( such as waterweed, plankton, etc. ) attached to the submerged water level transmitter . When cleaning the pressure gauge hole of the water level gauge, you can use trichloroethylene or alcohol to inject the pressure gauge hole to a half of its height and soak it for about 5 minutes, then shake it slightly and repeat it many times until it is cleaned. Do not use any appliance to clean the pressure-inducing hole to avoid damaging the sensitive core pressure-sensitive diaphragm. When cleaning the pressure interface and pressure hole of the transmitter, do not use excessively hard brushes or metal tools to avoid damaging the sensitive core and pressure interface threads. 投入式液位变送器 慢慢的放回铁管中,感觉已放置铁管的低部,将旋帽安装回原处即可。 After cleaning , put the drop -in liquid level transmitter back into the iron pipe slowly, feel that the lower part of the iron pipe has been placed, and install the screw cap back to the original position. After removing and cleaning and reinstalling, the installation depth will change to a certain extent, and the secondary water meter's detection value must be corrected again in accordance with the water level gauge at the same water level of the sluice to ensure the correctness of the sampling data.
