Level transmitters with a range of 400 meters belong to a larger range in the actual application process. In the field must pay attention to the following points to ensure that the level transmitter in the 400 meters range can be used normally. First of all, 400 meters range level transmitter can be vertical, inclined and horizontal installation, need to pay attention to whether it is installed in tanks or tanks, should ensure that there is no sand and other impurities on the level transmitter probe caused by clogging or buried. Secondly, due to the level transmitter range is large, will inevitably encounter fluctuations in the medium, when the medium fluctuations are large, the probe part of the liquid level transmitter should be counterweighted or use a fixed casing. In order to avoid the liquid level transmitter probe is damaged. Third, 400 meters range of the level transmitter shall use the gas shielding cable, this gas cable in addition to power and signal transmission, but also play a key role in atmospheric compensation. In the installation should be avoided on the level transmitter cable lock too tight or too sharp bends, to prevent the gas conduction can not be or broken. Fourth, hundreds of meters range of level transmitter in the field may need to install an extension cable, then you need to ensure that the wiring part of the ventilated and dry, forbidden to soak, and to avoid moisture, dirt clogging the cable center of the atmospheric connection pipe, otherwise it will cause damage to the level transmitter or measurement is not allowed.
