Overall View
The truck scale consists of four independent sections that work together as a complete weighing system. Each section is designed to handle specific portions of the truck weight while maintaining accuracy across the entire platform.
Working Principle
Independent Weighing System
The scales operate independently of each other while functioning as a complete system.
Vertical & Horizontal Limits
Special consideration for scale body shifting to maintain accuracy.
Longitudinal Limitation
Limit screws at the ends of first (3m) and fourth (6m) sections with 2-3cm space reserved.
Lateral Limitation System
The lateral/lateral limit is controlled by an additional limit plate on the end plate of the scale body. This prevents unwanted side-to-side movement while allowing for proper weight distribution

INDICATOR - ZM 510
User-centred design
Enclosures
Constructed for use in the office, dusty, wet or high pressure, heavy washdown and outdoor environments, the ZM510 is IP69K certified and enclosed in 304 brushed stainless steel. Designed for long service in extreme conditions, including corrosive environments and frequent, heavy washdown, the ZM510 adapts to desk, wall or column mount applications
Keypads
With metal domed tactile keys and audio contact confirmation, the ZM510’s large QWERTY keypad makes it flexible for use across all applications. Five programmable keys allow for specific weighing tasks to be assigned to the indicator, allowing weighing operations to be carried out quickly and effectively. The ZM510 can also be connected to a USB keyboard
Dot matrix graphical display
High contrast, Improved Super Twisted Nematic graphic display gives the ZM510 excellent visibility and colour contrast. With its wide viewing angles, the ultra bright green and black dot graphic display is easily visible in extreme working conditions and
The ZM510 is a high performance, multi-function indicator, flexible enough to adapt to complex weighing tasks. Programmable and highly connective, the ZM510 displays, analyses, stores, and transmits data across devices, offering an end-to-end, personalised weighing solution.
Remote Display Unit
The weight of the axles can be shown on large external displays with 120 mm high red LED digits making the information visible to the driver immediately. An external display can also show the gross weight of the vehicle.The large displays are fully waterproof. The displays show zero when the platform is idle and when overloads are detected, the appropriate display will flash, showing which sets of axles are causing the problem
