1. Product features and uses: This water level gauge is a national invention patent product of our company, with patent authorization number. 3. Exclusive certification from the National Lightning Protection Center in China, with certificate number (2004) Liangzhi (Hu) Zi (L0343). This product is a high-end instrument level input type liquid level transmitter designed specifically for water conservancy and hydrological monitoring in southern river network areas with multiple and low altitude mines, as well as mountainous areas in the north and south. It uses high-quality imported components with good stability and durability, and is made of selected high-end instrument discharge circuits. The integrated transmitter is equipped with a miniature three-level lightning arrester at the rear. The lightning protection device is installed in harsh installation environments of 3-5 categories, with long distances in the open air. According to the GB/T1762.5-1999 national standard, the strictest lightning resistance tests for electrical appliances are level 3 and level 4. Multiple lightning protection loads of 2kV/1kA and 4kV/2kA have been applied to the input and output lines, and they have passed safely. And according to GB18802.1-2002/IEC61643.1:1998, the ultimate impact strength test of power equipment products has passed the 10kV/5kA test.

This product is resistant to any strong induction lightning strike from a distance of five meters, and comes with a quality warranty (except for direct lightning strikes that burn the cable sheath).

2. Pressure range: 0~1, 2, 3, 5, 10~200 mH2O or measured in kPa

3. Material: The shell is made of standard stainless steel 1Cr18Ni9Ti, and the pressure sensing film is made of 316L stainless steel. It is suitable for slightly corrosive aqueous media

4. Output signal and power supply: 4-20mA 24VDC (18-36V)

5. Accuracy level:

Note: ⑴ The parentheses represent the indicators of low range products ranging from 1 to 3 meters, which should be relaxed according to international conventions;

⑵ J-grade products are all integrated products, and to ensure lightning protection performance, they do not accept split transmitter types;

If only sensors are needed, the performance and price will be negotiated separately;
