product overview：

The TQ-887 high-temperature densitometer adopts a strain sensing structure based on the principle of force balance. By combining the sensor with a sophisticated mechanical structure, it can directly measure liquid density and effectively solve the influence of static pressure. This instrument has outstanding characteristics of high temperature and high pressure resistance, and has the advantages of high accuracy, good reliability, easy adjustment, wide measurement range, and durability. Suitable for measuring density on open or closed tanks in the process flow, as well as through bypass tanks outside the process. Widely used in industries such as petroleum, chemical, power, food, water conservancy, metallurgy, heating, papermaking, cement, and sewage treatment.

TQ-887 is a two-wire instrument that can generate a 4-20mA current signal proportional to density, and the superimposed digital signal can provide remote monitoring and calibration functions (HATR protocol).
