Radio frequency admittance liquid level gauge is widely used in petroleum, chemical industry, metallurgy, electric power, papermaking, pharmaceutical and other fields.Products used in industrial and mining field, suitable for most applications, instrument by a circuit unit a set of explosion-proof enclosure and lever type or rope type of sensors, sensor has a variety of types of optional, instrument optional or fission installation as a whole.
Radio frequency admittance level installation requirements:
When sensor installation, need on-site set the reference electrode, such as metal cans wall conductor, then must ensure that the instrument shell keep good contact with the setting of reference electrode.If the container wall for insulator, watchcase must use a grounding conductor.
Radio frequency admittance level at the top of the installation:
Top mounted distancing himself from the liquid into the mouth, avoid when the feed liquid level fluctuation is bigger, in the process of measuring more than 3.6 m tank or container, need to choose soft cable, rf admittance level soft cable bottom fixed to a heavy hammer, avoid large sloshing into liquid soft cable.
Hard bottom bar type sensor is generally not fixed, special circumstances in the middle of the bottom or plus fixed support, cable type sensor to aggravate the hammer or anchor fixation.
Radio frequency admittance level to note:
1, the radio frequency admittance installation location not being too close to the mouth, otherwise, rf admittance level meter when the material is easy to receive fake echo.
2, rf admittance for the original coal cylindrical, VEGA should be installed in the cylinder radius in half, the sensor should be aimed at discharging port.
3, rf admittance model is needed for the different voltage grade are not identical, to ensure the personal safety and equipment in good condition, should be in the case of power wiring.
4, connection mode can be divided into two wire system, rf admittance level meter acquisition is 4-20 ma current signal, to prevent electromagnetic interference on site, ensure the accuracy of signal, should use shielded cable, shielding grounding cable end.
