1. Performance Overview
The MT-YLG-XL-C0-04 is a fully automated pressure testing system with a throughput capacity of up to 1,200 cans per minute. It employs a contact-based online detection method, ensuring direct and precise measurement of internal container pressure. Test results are stable and highly reliable, with an accuracy level superior to comparable domestic and international systems.
Its core belt-squeeze detection technology, developed through more than three years of testing and optimization, uses a flexible transport belt to convey cans (or bottles). Pressure sensors mounted on the belt sides capture internal pressure data, which is then converted into digital signals by the controller. The processed results provide real-time insights into container pressure and product quality.

5. Schematic diagram of equipment extrusion
We add a guide mechanism at the front end to pre-squeeze the cans to maintain a certain pressure. If there is a leak, we release the pressure as fully as possible and measure the pressure at the tail end. If there is no leakage, the pressure change will not be much, but if there is a leak, the pressure will be much different from the normal one. In this way, we can reliably detect leaks and products with poor sealing effects.
6. Equipment detection principle
When a product passes the belt, it passes the positioning sensor, which detects its arrival and records the product's identification number and the current encoder signal through the control unit. The positioning sensor triggers the force sensor to measure the instantaneous pressure exerted by the product against the belt. This pressure data is then transmitted to the Maotong signal processing board via the network. The signal processing board processes and analyzes the received pressure data, transmitting the results to both the human-machine interface for dynamic display and the control unit. Upon receiving a rejection signal, the control unit notifies the rejector to remove the product with the corresponding identification number that fails the pressure requirement.
II. Equipment Installation
1. Equipment Loading, Unloading, and Storage
During transportation, the equipment must be secured and packaged, with particular attention to preventing the sensor from being subjected to pressure or tension. The exterior of the equipment must be wrapped with moisture-proof, impact-resistant material to prevent scratches, dents, and moisture. The equipment must be secured to the transport vehicle to prevent damage during movement. When unloading the equipment, use specialized loading equipment and ensure that the equipment is securely mounted on the loading equipment to prevent slipping. During use and storage, the ambient environment must meet certain requirements: relative humidity should be between 10% and 80%, and temperature between 0°C and 50°C.
II. Installation Requirements
2.1 The equipment must be installed horizontally, ensuring that the clamping conveyor belt runs parallel to the product’s bottom conveyor belt.
2.2 Prior to connecting the power supply, carefully check that all cables are secure and that the grounding wire of the control cabinet is properly connected.
2.3 Power connection: Single-phase AC 220V, 50Hz, total power 250W.
2.4 Air connection: Compressed air pressure 4–8 bar, meeting industry quality standards.
2.5 For optimal detection performance, products should be tested after cooling. The unit should be installed on a straight conveyor section of 1.5–2m in length.
III. Equipment Structure & Specifications

IV. Safety Instructions
Before operating the equipment, please observe the following precautions:
Only trained personnel are authorized to operate the machine.
Maintenance and servicing must be performed by qualified technicians.
Ensure all protective devices and warning labels are in place before startup.
Do not operate the unit with covers open; always switch off power and compressed air before opening.
Keep hands away from the reject cylinder linkage during operation.
Do not block or touch the photoelectric trigger switch while the machine is running to prevent accidental ejection and injury.
Do not unplug or disconnect electrical wiring while the machine is powered on.
Place warning signage during maintenance to avoid accidental operation and injury.
Before connecting external devices, ensure both systems are powered off. Restore power only after the connection is secured.
The electronic components are static-sensitive; therefore, the frame and control cabinet must be reliably grounded.
