Mid-temperature 2-color Ratio Pyrometer
This classification includes two color infrared pyrometers measuring range start from 600℃. Compared to one color infrared pyrometers, two color pyrometers have more strength. Two-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected.

Because the density of the location of the float is relatively fixed, that is, the percentage of oil and catalyst is relatively fixed. From the above formula, it can be seen that Ï1 and Ï2 are relatively fixed, and the buoyancy of the float is fixed. The float floats accurately on the interface and the liquid surface, thus ensuring high-precision measurement of the magnetostrictive level gauge. 
The magnetostrictive liquid level gauge can measure the liquid level and the interface at the same time. In the DCS, the addition and subtraction module uses the liquid level value minus the interface value to obtain the exact height of the oil, and solves the problem that the LT2 in FIG. 1 can only measure the upper part of the oil level. Makes the process operator more aware of the conditions inside the reactor. Differential Pressure Transmitter Pilot Tube Steam heating in winter can cause vaporization of the liquid in the pressure guide tube. It is necessary to perform regular exhaust and filling of the spacer fluid. When the material contains impurities, it will cause the instrument to be blocked. The maintenance personnel of the instrument will have a heavy workload. After the magnetostrictive level gauge, the maintenance of the meter is reduced much.
Magnetostrictive level gauge as a new measuring instrument has the advantages of high precision, good stability and reliability. It is more suitable for interface level measurement. In the future, there will be a larger market in the petroleum, chemical, pharmaceutical and other industries.
A schematic diagram of a typical chemical reactor level measurement in a chemical plant. Above is the oil (benzene and its compounds) The following is a liquid catalyst. Because the density of the catalyst is greater than that of the oil, the two materials are automatically separated. The process operator controls the catalyst, oil interface (LT1 measurement) and oil level (LT2 measurement) to ensure the formation of the synthesis reaction. The two liquid level values ​​must be precisely controlled within a certain range, which is the system parking interlock point.
