　　Functional characteristics of pressure type water level gauge

　　1. Good stability, with a long-term stability of 0.1% FS/year at full and zero positions. Within the compensation temperature range of 0-70 ℃, the temperature drift is less than 0.1% FS, and within the entire allowable operating temperature range, it is less than 0.3% FS.

　　2. Equipped with reverse protection and current limiting protection circuits, the transmitter will not be damaged if the positive and negative poles are reversed during installation. In case of abnormalities, the transmitter will automatically limit the current to within 35MA.

　　3. Solid state structure, no movable parts, high reliability, long service life.

　　4. Easy to install, simple structure, economical and durable.

　　Performance and advantages of pressure type water level gauge

　　1. Its mechanical structure has high resistance to overload and corrosive media.

　　2. High precision, long-term stable ceramic capacitors and imported diffused silicon measurement units.

　　3. The sealed electronic module and dual filtering pressure compensation system can resist the impact of on-site climate changes.

　　4. An electronic module that can output 4... 20mA signals and is equipped with overvoltage protection.

　　5. Choosing the integrated temperature sensor Pt100 allows for simultaneous measurement of both level and temperature.

　　6. The corresponding attachments can provide a complete measurement plan.

　　The pressure type liquid level gauge adopts the principle of static pressure measurement. When the liquid level transmitter is put into a certain depth of the measured liquid, the sensor is subjected to pressure on the liquid surface. At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the gas guiding stainless steel. Then, 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. By measuring the pressure P, the depth of the liquid level can be obtained.

　　The pressure type water level gauge is made of advanced isolated diffusion silicon sensitive elements, which can be directly put into a container or water body to measure the height from the end of the water level gauge to the water surface, and output the water level value through 4-20mA current or RS485 signal to the outside.
