Summary:
The octane number of diesel fuel cetane number tester is used for petroleum refining enterprises, oil storage and oil adjusting units to determine the octane number of gasoline (including aviation, national standard, blending, ethanol) and diesel fuel cetane number of special instruments. The instrument adopts large screen display, the back light is soft, and the interface font is clear.
LR-637 Diesel Cetane Number Tester Blended Gasoline Cetane Meter Diesel Fuel Octane Number Analyzer
Four technological innovations:
|
1. Digital sensor. Strong anti-interference ability, small variation, high precision; Reproducibility, repeatability is good. 2. The instrument calibration program adopts automatic assignment calibration technology, and the calibration results are accurate and reliable. 3, the determination procedure can be automatically regression, ASTM--CFR testing machine determination results as the standard, targeted regression, improve the determination accuracy, expand the determination range. 4, for aviation gasoline, vehicle gasoline, mixed gasoline, ethanol gasoline, vehicle diesel, through the first regression can do a key determination. |

Working principle:
Gasoline octane number determination principle is according to GB/T5487, the use of ASTM - CFR testing machine to achieve, is also internationally recognized. It is a method of determination under test conditions: a standard engine with variable compression ratio is taken as the means, and the reference fuel is taken as the standard. The instrument is used to measure the synthetic dielectric constant of oil components. Is based on rigorous mathematical model for regression theory, by means of advanced electronic measurement technology, on the basis of CFR tester determination results, targeted for automatic regression, the determination of targeted can ensure measurement accuracy, broke through the quantity cannot dissemination, implements the CFR tester tester of dissemination.
The instrument consists of a microcomputer and a sensor. The signal collected by the sensor is transmitted to the input terminal of microcomputer and processed by CPU to display the measurement result. Screen display (research method, motor method, anti-knock index), and can be stored, read, browse, print. Working principle circuit block diagram is as follows:
