product overview:

The TQ-889 series online input density (concentration) sensor is an instrument for continuous online measurement of liquid density, mainly used for industrial process automation control. Generate corresponding 4-20mA analog signals based on changes in medium density, and convert them into digital signals for remote calibration and monitoring. According to different industrial processes, density can be expressed as Brix degree, GL degree, Baume degree, Plato degree, and concentration percentage.
The TQ-889 series online input density (concentration) sensor can be widely used in industrial sites such as pipelines, open or closed storage tanks, etc. It can continuously and real-time measure the liquid density of pipelines or tanks online.
Product features:
*The engineering units that can be used for direct density or concentration readings include:
g/cm3、kg/m3、 Specific gravity, ° Brix, ° Baume, ° Plato, ° GL, solid percentage content, etc
*Suitable for flowing or stationary liquids
*Suitable for density measurement of pipelines and tanks
*Adopting an integrated structure with no moving parts
*Standard industrial and sanitary process connections
*The converter can be optionally equipped with GPRS wireless remote transmission function
*The instrument is equipped with a built-in temperature sensor, providing accurate temperature compensation
*Online remote verification, digital local display
*Factory multi-point linear correction for higher accuracy
*On site recalibration: No need for standard reference sources, no need for experimental calibration, no process interruption
*The converter is compatible with three installation methods: wall mounted, embedded, and desktop
*The converter adopts a touch screen display, with a more user-friendly interface
