The  CCS machine ASTM D5293 engine oil (CCS) or Cold Crank Simulator is used to determine the oil viscosity in cold and -5 to -35 degrees in various types of engine oil. The CCS device is in accordance with ASTM D5293 standard.

Viscosity measurements are required for each condition monitoring (CM) software. One of the basic properties of oil is viscosity. Changing the viscosity is very dangerous for the car and causes serious damage. Because viscosity varies greatly with temperature, the tools used to measure viscosity must take this parameter into account in viscosity calculations.

For this purpose, more viscometers ( viscometer ) must maintain a constant temperature oil tested. It is generally used to measure viscosities of 40 degrees and 100 degrees. Conventional devices have an oil bath in which the temperature of this oil is fixed at one of the above temperatures (with an accuracy of 0.01 degrees).

To measure, the test oil is poured into capillary tubes in the oil bath and the time of movement of the oil is measured at a certain distance and the viscosity of the oil is calculated using equations or control tables.

To accurately measure viscosity, the oil must first be filtered so that the used oil particles do not clog the capillary tubes and affect the oil transfer rate. It is also necessary to rinse the capillary tube well after each test so that the remaining oil has no effect on the measurement. As can be seen, measuring viscosity in this way requires a lot of time and high accuracy.

One thing to keep in mind is that the purpose of monitoring the situation should not be forgotten. The main purpose of monitoring is not to measure the viscosity of the oil, but to compare the viscosity of the oil with the previously measured values.

The purpose is not to measure viscosity, but to look for changes in viscosity. This is an important point to keep in mind when working with laboratories. The purpose of the viscosity measurement workshop is to observe changes in previous measurements. So if the goal is not to really measure the viscosity of the oil, we can use simpler equipment for this test.

ccs is designed and built with the same idea. In this instrument, the viscosity of the test oil is compared with the reference oil. Because these two oils are used for measurement and comparison, the effect of temperature on these oils is very similar. Therefore, to measure the viscosity, there is no need to stabilize the temperature properly and the reference oil can be selected to measure the viscosity at 40 ° C at ambient temperature (300 ° C).

ccs has two tubes, one of which contains reference oil. This oil is a special oil that is prepared by the manufacturer and the consumer can not reach it. The second tube looks like a syringe and draws the test oil into it like a syringe.

There is a small wire inside the pipes. The size of the bullet makes it easy to move inside the tube. After applying the test oil to the second tube, hold the instrument with the lead in the zero position to measure the viscosity. Then place the device horizontally, and gently lift the tip of the device 25 degrees. The bullets start moving.

When each bullet reaches the end of the tube, rotate the device horizontally and the other bullet reads the viscosity of the oil in centimeters from the ruler in front of it.

The accuracy of this device is less than 3%. This value allows the viscometer to be used to monitor conditions. Because monitoring the change in viscosity up to 5% is often not enough for action.

For example, if the viscosity of unused oil is 100 and the viscosity of used oil is 95, then this measurement does not yet require any practical action.

The CCS device is fully automatic and has a touch screen.

This machine is used in oil and grease laboratory, oil and gas laboratory, petrochemical laboratory, refineries, standard laboratories and research laboratories.
