Water Level Sensor section
1. Equipment introduction:
The equipment adopts imported sensor cores from abroad, which convert the liquid level and pressure signals into corresponding digital signals, and then process them through digital circuits to output RS485 two-wire standard signals. The integrated design encapsulates the isolated sensor and digital processing circuit inside the probe, and directly outputs the 485 digital signal corresponding to the liquid level pressure through a special cable.
2. Application direction:
Open water tank, water tower level;
Rivers, lakes, wells, dams, groundwater levels, etc;
Urban water supply and sewage treatment;
Water conservancy construction, irrigation, drainage water level monitoring, etc;
Oil level in the fuel tank of diesel power generation equipment and hydropower equipment;
Alcohol and other organic solvent levels.
3. Advantages and features of equipment:
★ High performance sensor, digital processing circuit, all stainless steel structure;
★ Special moisture-proof treatment, product protection level IP68, reliable waterproof sealing;
★ Polyurethane waterproof and oil resistant cables, resistant to various complex media, and reliable and durable;
★ Equipped with automatic pressure and temperature compensation;
★ The product has the characteristics of compact structure, sturdy, corrosion-resistant and overload resistant, and easy to use;
★ According to customer requirements, lightning protection modules can be configured
