Main model: YCCH-3

　　Scope of application: power plant double inlet and double outlet coal mill level measurement system

　　Differential pressure and material level detection system is a part of the control of a direct-blown steel ball mill. It applies the principle of depth probe measurement to a container with varying pressure and is developed to measure the thickness of materials with a differential pressure value.

　　The system consists of three major parts and twelve subsystems:

　　1. Measurement part: PID control constant voltage source circuit, constant current source circuit, backflow prevention circuit, self-checking subsystem of running status.

　　2. Cleaning part: cleaning control circuit, cleaning main circuit, cleaning back pressure subsystem, cleaning pressure measurement subsystem.

　　3. Control part: microcomputer (PLC) intelligent software control system, human-machine conversation (HMI) system, differential pressure level signal output subsystem, fault alarm output subsystem.

　　Nantong Nantong Lubrication Hydraulic Equipment Co., Ltd. has developed three generations of products, applied for and obtained 1 national invention patent (Patent No.: ZL200710019779.1). "YCCH Rotary Vessel Intelligent Differential Pressure Thickness Measurement System" won the title of "High-tech Product of Jiangsu Province" in 2007.
