Product Name: CAP3024-21113 intelligent oil gauge
Product description:
CAP-3024 intelligent capacitance oil gauge is the use of radio frequency capacitance detection technology, combined with industrial grade range measurement system of temperature drift compensation technology, liquid dielectric constant change automatic compensation technology produced. It is designed for industrial environment gas (vapor) phase medium oil, oil-water interface measurement occasions relatively stable production.
This product by the national instrument explosion-proof safety supervision and inspection station (N E P S) certification. Intrinsically safe explosion-proof flag for E x a I C T 6 / T 5, can be used for the corresponding explosive hazardous sites in the area of I I.
Working principle
The change of oil, oil-water interface and the relation between the measured capacitance change pole of the capacitance change detection by measuring system of temperature drift compensation, liquid dielectric constant changes after compensation by the special mode of software processing, corresponding to 4 ~ 20 m A analog current loop and change and oil-water interface the two line output and the level change is proportional to the system of the four groups of S P S T (N O) solid state relay.
