Kyushu Shengxin analytical debugging method of input type liquid level gauge
The input liquid level gauge is suitable for chemical industry, metallurgy, power station, water conservancy, urban water supply and industrial wastewater. The product is widely used in acid-base liquid level measurement, accepts a hydraulic signal proportional to the liquid level height, and converts it to a 4-20mA standard current output, which is sent to a computer, recorder, regulator, etc. to achieve the acid-base liquid level Display, alarm and automatic control. The parts in contact with the liquid are all made of all-tetrafluoroethylene material, which has high temperature resistance, corrosion resistance and anti-clogging, and is widely used for the measurement of the liquid level of any liquid under normal pressure (except for the medium that corrodes tetrafluoroethylene)
Anti-corrosion input liquid level transmitter debugging method:
Unscrew the protective cover, you can see the zero-adjustment and full-range resistor, external standard power supply and ammeter (level 0.2 or more), you can adjust, the steps are as follows:
â—† When the transmitter has no liquid, adjust the zero resistor to make it output current 4mA;
â—† Add liquid to the full range of the transmitter, adjust the full range resistor to make the output current 20mA;
â—† Repeat the above steps two or three times until the signal is normal;
â—† After adjustment, tighten the protective cover.

Stainless Steel cups are made from high-grade 18/8 stainless steel. This material is food grade, non-toxic, durable and easy to clean.
Our Stainless Steel cups are mostly Stainless Steel Vacuum Water cups. They have a double-wall vacuum treatment, so they can ensure your drink keeps as it is. And you don't need to worry about getting your hands cold or hot.
Stainless Steel Single Wall cup has a single wall. It sacrifices thermal insulation and improves portability. Holding it in your hand all the time will not cause any discomfort.
