TQ-880 anti-corrosion densitometer Introduction: The TQ-880 series online density (concentration) sensor is a high-precision density (concentration) measuring instrument based on the static pressure principle introduced by Beijing WorldCom Technology Co., Ltd. The TQ-880 series in-line density (concentration) sensor is a continuous online measuring instrument for liquid density, mainly used for industrial process automation control. The corresponding 4-20 mA analog signal is generated according to the change of the medium density, and the digital signal can be converted and output for remote calibration and monitoring. Density can be expressed as: Brix, GL, Baume, Plato, and percent concentration, depending on the industrial process. The TQ-880 series of online density (concentration) sensors can be widely used in industrial sites such as on-site pipelines, open or closed storage tanks, and can continuously and in real-time measure the liquid density of pipelines or tanks. Features: 1. Direct density or concentration readings, available engineering units include: g/cm3, kg/m3, specific gravity, °Brix, °Baume, °Plato, °GL, percent solids, etc. 2. Suitable for flowing or stationary liquids 3. Suitable for tank density measurement 4. Two-wire system uses 4-20mA/Hart output 5. Adopt integrated structure, no moving parts 6. Standard industrial and sanitary process connections 7. Converter can be equipped with GPRS wireless remote transmission function 8. Meter built-in temperature sensor for accurate temperature compensation 9. Online remote verification, digital local display 10. Factory multi-point linear correction, higher precision 11.
