• Moduláris Kompatibilitás: Compatible with a wide range of Intercomp weighing instruments, including wheel and axle load scales (e.g., PT300™, LP600™), Jack Weigh Kits, and aircraft platform scales (AC series).
• Robust Design: Built to withstand harsh industrial and outdoor environments, ensuring reliable operation in the most diverse locations.
• Data Management Functions: Enables storage, display, and export of weight data, supporting subsequent analysis and compliance documentation.

Technical Specifications (PT20™ CPU)

Although the precise, complete specification list can be found in the manual supplied with the product, the table below summarizes the key technical parameters characterizing the PT20™ CPU:

Application Areas Details

The PT20™ CPU systems provide outstanding performance in the following areas:

1. Automotive and Freight Applications

The PT20™ CPU is the ideal accessory for portable wheel and axle weighing systems, which are essential for adhering to central regulations and optimizing vehicle loads.

• Portable Scales: Compatible with systems such as the LTR788™ (dual wheel load scale) or the PT300™ wheel load scale, enabling fast on-site measurements.
• Axle Load Weighing: Provides precise weight data for axle load enforcement, helping carriers avoid overloading and preventing fines.
• Weigh-In-Motion (WIM) Systems: Although primarily used for static measurements, the RFX® CPU can be integrated with low-speed WIM systems (e.g., LS630-WIM™), where wireless data transmission increases flexibility.
• Commercial Fleets and Construction Sites: Assists in the precise distribution of cargo, optimizing vehicle stability and lifespan.

2. Aerospace Weight & Balance

In the aviation sector, precision is not just a requirement, but a safety mandate. The PT20™ CPU plays a key role in determining aircraft weight and center of gravity.

• Aircraft Platform Scales: The CPU communicates directly with platform scales such as the AC15-LP™ or AC60-LP™, ensuring precise measurement of wing, main gear, and nose gear weights.
• Jack Weigh Kits: The RFX® wireless technology allows the use of AC100™ or EZ RFX® Jack Weigh Kits without the load cell cables obstructing work around the service stands.
• Weight & Balance Calculations: Based on the collected data, the CPU or the connected software (e.g., ACWeigh™) immediately calculates the center of gravity, assisting pilots and ground crew in setting safe flight parameters.

Advantages of Wireless Technology with the PT20™ CPU

The integration of the RFX® wireless system into the PT20™ CPU provides significant operational advantages:

1. Quick Installation: Load cells can be quickly positioned under the vehicle or aircraft and immediately connect to the central CPU, drastically reducing setup time.
2. Safety: The absence of cables minimizes the risk of tripping in the work area, which is especially important on crowded tarmacs or in maintenance pits.
3. Interference Management: The RFX® protocol utilizes advanced encryption and frequency hopping to ensure clear signal transmission even in environments with high electromagnetic noise.
4. Portability and Flexibility: The PT20™ CPU is easily portable between different measurement locations while maintaining communication with remotely located load cells.

Software and Data Management

The PT20™ CPU is not just a data collector; it is an intelligent processing unit. While precise software integration depends on the specific application (e.g., aerospace ACWeigh™ or vehicle applications), the basic functions of the CPU include:

• Real-Time Display: Instantaneous update of weight values on the connected display.
• Zeroing and Tare: Ability to zero the load cells or subtract the weight of a vehicle/container (tare measurement).
• Data Logging: Recording of measurement cycles with a timestamp, which is essential for quality assurance and compliance audits.

The Intercomp RFX® Wireless CPU (PT20™ CPU) represents the pinnacle of modern measurement technology, combining wireless freedom with the reliability of precision industrial measurements.
