Filter cartridge pore size tester

Implementing standards

1, ISO 2942-2004 Hydraulic transmission - Filter element - Verification of structural integrity and determination of initial bubble point

2, GB/T 14041.1-2007 Hydraulic filter element Part 1: Verification of structural integrity and determination of initial bubble point

3, ISO 4003-1990 Determination of void size for the bubble test of permeable sintered metal materials

4, GB/T 5249 -2013 Determination of bubble test pore size of permeable sintered metal materials

5. JB/T 5089.3 Test Methods for Internal Combustion Engine Paper Filter Element Oil Filter Part III

Test Items

1. Structural integrity (filter material with or without breakage, machining damage, and defects at the seam of the filter element and the end cap adhesive bonding)

2. Pressure value of the first bubbling point and maximum pore size value

3. Pressure value of the bubble point of a group of values and the average pore size value

4. Filtration Precision value (reference value corresponding to βx≥20)

Functions and features

1. Appearance material: stainless steel panel, aluminum alloy profile frame, laser engraved logo, not easy to fall off.

2、Display: it is resistive touch screen.

Operating system: the new version of Android system, as if the smart phone operation.

3, test data a key to lock, an interface to complete all operations, easy to get started, 10 minutes to get started.

4, stability: ergonomic design, the use of Germany Festo regulator control valve, improve the stability of the equipment in the operation of the pressure rise rate.

5、“Blow dry” function: reduce the loss of test liquid, shorten the drying time of the test piece, protect the test cartridge.

6、The test state of filter element and filter material can be switched by one key.

7、The machine itself is small and easy to move. Office personnel on the desk that can be used (placed in a position to avoid resonance).

8, temperature compensation: surface tension in the temperature range (18-37 ℃), the program can be self-compensating arithmetic, the test results are not affected by changes in external temperature.

9, built-in 6 kinds of filter material optional reference filtration accuracy.

10、Mass storage: test data can be saved in millions, convenient for querying at any time.

11, print mode: according to the test results, three modes of printing, and can query the historical data and printing at any time.

12, calibration function: comes with calibration port, you can calibrate the error value of the pressure sensor at any time.

13、Automatic correction function:

(1) After inputting the temperature sensor error, it can be corrected automatically;

(2) After inputting the error of differential pressure sensor, it can be corrected automatically.

13, can be upgraded at any time through the data interface for the operating system

Main Technical Parameters

1, the working medium: compressed air (installed outside the body, give power to the automatic start-stop);

2, the test applies to the liquid: recommended use of isopropyl alcohol (filter), industrial ethanol (cartridge)

3, the test of the maximum pressure: 15KPa

4, the accuracy of the pressure adjustment: (5 ~ 50) Pa

5, the measured diameter of the filter media: 88mm

6, the pore size Tester range: (5.8~100)μm

Test bench configuration options

1, test tanks
