PRC has designed, developed & manufactured a dedicated air leakage testing machine for cover cylinder head which is unique in design. It is equipped with fixtures and other attachments with audio visual alarm for OK & NG.

Features of Parametric Leak Testing Machines:

• Highly accurate & dependable
• Quick leak detection
• Multi-channel operation
• Smart pneumatic & electronic circuits
• Easy calibration through Leak Masters.
• PC Interface through RS 232 C
• Pressure Decay leak measurements
• Strain gauge based pressure transducers / transmitters.

Theory of working:

The original dry-air method is pressure decay, in which the test part is pressurized and then isolated from the pressure source. Because air moves from a high-pressure area to a low-pressure area, any decrease in pressure indicates the presence of a leak. Algorithms then convert pressure changes into an approximation of the leak rate.

HMI (Human Machine Interface) is a medium for information exchange and mutual communication between electromechanical systems and the user. It allows the user to complete settings through touchable images or keys on the user-friendly window. This not only offers fast and convenient control of manufacturing automation, but also has replaced traditional controlling panels which need extensive wiring.

Human Machine Interface (HMI) equipment provides a control and visualization interface between a human and a process, machine, application or appliance. HMIs allow us to control, monitor, diagnose and manage our application.

The Human Machine Interface (HMI) includes the electronics required to signal and control the state of industrial automation equipment. These interface products can range from a basic LED status indicator to a 20-inch TFT panel with touch screen interface. HMI applications require mechanical robustness and resistance to water, dust, moisture, a wide range of temperatures, and, in some environments, secure communication. They should provide Ingress Protection (IP) ratings up to IP65, IP67, and IP68.

Features and Benefits

Supports high source and sink output IO capabilities up to 60mA for direct drive of LEDs. High-speed PWM units enable LED dimming and screen back lighting. Robust touch technology provides reduced wear and increased product lifetime. The excellent signal-to-noise ratio makes the design immune to water, moisture, or dust and enables operators to use gloves. Capacitive touch eases design of full hermetic or sealed products, while power efficiency minimizes heat dissipation.
