Roller compression force tester: a precision instrument specifically designed to measure, analyze, and optimize the pressure distribution within the compression zone. It is usually a thin thin film with a large number of high-precision sensors placed between two rollers to simulate production conditions and perform measurements.
Product Details
Applicable scenarios: The drum pressure tester is mainly used to measure the combined pressure between drums, that is, the pressure values of two rollers. It can measure the combined pressure gap and pressure between different drums, and is suitable forUsed for various drum combinations, such as metal to rubber, rubber to rubber, etc.
Roller compression force testerAdvantages:
Accurate measurement of pressure distribution: It can measure the peak pressure in the contact area of the drum.
Wide measurement range: The low voltage range is 3-60 N/cm ²,
The high voltage range is 20-999 N/cm ².
Easy to operate: Measurement can be done by pulling the sensor sheet over the pressure zone, and the display results are intuitive.
The range of 20-999 Newton (N) is relatively large and suitable for measuring large pressures. In offset printing machines, if it is necessary to measure a large range of pressure, such as when adjusting the macroscopic pressure distribution between the rollers,
A tester with this range may be more suitable. For example, during the initial installation and debugging of the drum, it is necessary to ensure that the contact pressure between the drums is within a reasonable range to avoid printing quality problems or equipment damage caused by excessive or insufficient pressure.
The range of 3-60 Newton (N) is relatively small and more suitable for precise measurement. In the offset printing process, the pressure between the rollers needs to be controlled very precisely, especially when printing fine patterns or high-quality printed products.
A pressure range of 3-60 Newtons may be more suitable for measuring the fine adjustment pressure between the rollers, ensuring uniform and stable pressure during the printing process, thereby ensuring printing quality.
Basis for selecting pressure range
1.Printing requirements: If ordinary paper is being printed and the printing quality requirements are not high, a larger pressure range (such as 20-999 Newtons) may be sufficient. Because in this case, the pressure between the rollers does not need to be controlled very precisely.

If high-quality picture books, brochures, etc. are printed, or special paper (such as copperplate paper, specialty paper, etc.) is used, more precise pressure control is required, and a pressure range of 3-60 Newton may be more suitable.
2. Equipment accuracy requirements: The higher the accuracy requirements for offset printing machines, the higher the accuracy requirements for measuring drum pressure. If the device itself has high accuracy and requires precise adjustment of drum pressure, then a pressure range of 3-60 Newtons may be more advantageous.
If the accuracy of the equipment is relatively low, or if the main focus is on the macroscopic pressure distribution between the rollers, then a pressure range of 20-999 Newtons may be more practical.

Actual application scenarios
Equipment installation and debugging phase
During the installation and debugging phase of the offset printing press, it may be necessary to use a pressure range of 20-999 Newtons to initially adjust the pressure between the rollers to ensure that the equipment can operate normally.
Daily printing production stage
In daily production, if fine printing is required, a pressure range of 3-60 Newton may be used to fine tune the drum pressure to ensure printing quality.
In short, the selection of a drum pressure tester with a certain pressure range needs to be comprehensively considered based on specific printing requirements, equipment accuracy requirements, and actual application scenarios.

All composite pressures have a pressure curve. When the thin sheet of the tester passes through the required measured compression area (roller compression), the roller pressure tester monitors how the pressure increases
Transform. The tester will display the peak pressure (maximum value) on the display screen.

Contactless is safer
The pressure indicator adopts the latest nanotechnology, which can quickly measure the indentation pressure between the rollers. The pressure sensitive area of 5 x 5 millimeters passes through a small opening under pressure, and the instrument records the absolute pressure level thousands of times.
All composite pressures have a pressure curve. When the thin sheet of the tester passes through the required measured compression area (roller compression), the roller pressure tester monitors how the pressure increases and changes. The tester will be displayed on the screen
Display the peak pressure value (maximum value) in the middle. When a pressure sensitive area of 5 x 5 millimeters passes through an overpressure zone under pressure, the instrument will record thousands of absolute pressure levels. And it will maintain the display of the highest value - peak pressure.
Easy to operate
Let the roller pull the Jian end of the sensor blade over the pressure zone and then stop. The pressure in the compression zone will be displayed immediately
2. Reverse the roller or lift it up
3. Adjust the roller if necessary and repeat the measurement
