Sincerely thank you for choosing our company's anti-corrosion and anti blocking productsInput type liquid level transmitterYe Li is a professional manufacturerManufacturer of input type liquid level gaugeMoreover, the price of the input type liquid level gauge is discounted,How much does an input level gauge cost? Please contact customer service for a quote,Large quantities are preferred! The new structure of this liquid level transmitter is developed based on the gas conducting cable type anti-corrosion and anti blocking input liquid level transmitter. The adoption of a new structure solves the disadvantages of traditional gas cable type liquid level transmitters, such as being afraid of blockage, prone to corrosion, and not resistant to high temperatures. The WMY-A diffusion silicon level transmitter is a two-wire system, with 4-20mADC output and 24VDC DC power supply. The parts in contact with the medium are all made of stainless steel and can be directly installed on the measuring pipeline. It is extremely convenient to use and widely used in process control and level measurement in industries such as petroleum, chemical, metallurgy, water conservancy, power, food, medicine, and environmental control.

Debugging method:
Unscrew the protective cover to see the zeroing and full range resistors, which can be adjusted by connecting an external standard power supply and an ammeter (0.2 poles or more). The steps are as follows:
◆ In the absence of liquid in the transmitter, adjust the zero point resistor to output a current of 4mA,
◆Anti corrosion and anti blockingInput type liquid level transmitterAdd liquid to full range, adjust the full range resistor to output a current of 20mA,
Repeat the above steps two or three times until the signal is normal.
◆ After adjustment, tighten the protective cover.

matters needing attention:
All supplied products come with user manuals and certificates of conformity, which include product numbers, technical parameters, manufacturing dates, etc. Please carefully check to avoid errors.
When connecting to the power supply, strictly follow our company's wiring instructions for connection.
If any abnormalities are found during use, the power should be turned off, the use should be stopped, and inspection should be carried out, or directly contact our company's technical department.
During transportation and storage, the original packaging should be restored and stored in a cool, dry, and ventilated warehouse.

working principle:
Principle of static pressure measurement:
When the liquid level transmitter is inserted into a certain depth of the measured liquid, the pressure formula on the sensor facing the liquid level is: Ρ=ρ.g.H + Po
In the formula:
P：Anti corrosion and anti blockingInput type liquid level transmitterPressure exerted on the liquid surface
ρ： Density of the tested liquid
g： Local gravity acceleration
Po： Atmospheric pressure on the liquid surface
H： Depth of liquid input into the transmitter
At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through gas guiding stainless steel, and the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ.g.H， Obviously, by measuring the pressure P, the depth of the liquid level can be obtained.
