ZONESUN ZS-MD818 Button-Type Automatic Metal Detector and Checkweigher with Reject System

ZONESUN ZS-MD818 Button-Type Automatic Metal Detector and Checkweigher with Reject System

Description

The ZONESUN ZS-MD818 Automatic Metal Detector and Checkweigher combines metal detection, dynamic weighing, and automatic rejection in one continuous system. Products are inspected for ferrous, non-ferrous, and stainless-steel contaminants, then weighed against preset tolerances on the conveyor. Items with metal or outside the weight range are automatically rejected, while qualified products continue downstream. The metal detection unit uses a button-type control panel, while weight control is managed via touchscreen, with high-speed inspection for automated lines requiring integrated safety and weight quality control.

Key Features

Button-Type Metal Detector Controller
Allows operators to set detection parameters and sensitivity through a simple button-operated interface for convenient product metal inspection.

Touchscreen Control Panel
Allows operators to set target weight, tolerance limits and operating parameters while monitoring inspection results and machine status in real time.

Metal Detector
Detects ferrous, non-ferrous and stainless-steel metal contaminants as products pass through the inspection tunnel.

Dynamic Weighing Conveyor
Measures product weight during continuous conveying and compares each product against the preset acceptable weight range.

Automatic Reject System
Automatically removes products that contain detected metal contaminants or fall outside the preset weight range, allowing qualified products to continue downstream.

Independent Dual Control
The machine features two separate control interfaces: a button-type metal detector controller for metal detection parameter and sensitivity adjustment, and a touchscreen control panel for checkweighing settings and monitoring.

High-Speed A/D Sampling Controller
Uses a high-speed A/D sampling control system for accurate dynamic weighing and stable inspection performance.

100 Product Presets
Supports up to 100 preset product numbers, making it easier to manage inspection parameters when switching between different products.

Push-Rod Reject System
Uses a push-rod type rejection mechanism to automatically divert non-conforming products from the main conveyor.

SUS304 Stainless-Steel Construction
The machine uses SUS304 stainless steel, providing a durable structure suitable for industrial packaging and inspection environments.

Benefits

Button-Type Metal Detection Control
Provides independent adjustment of metal detection parameters and sensitivity through a simple button-operated interface, offering straightforward control of the metal inspection section.

Integrated Metal Detection + Checkweighing
The biggest advantage of the ZS-MD818 is the integration of metal contamination inspection and dynamic weight inspection into a single conveyor system.

Detects Multiple Metal Types
Detects ferrous, non-ferrous, and stainless-steel contaminants, providing comprehensive inline metal inspection.

Real-Time Dynamic Weighing
Products are weighed continuously while moving through the conveyor, supporting efficient production without requiring manual weighing.

Automatic Non-Conforming Product Rejection
Products that fail either the metal detection or weight inspection are automatically removed from the production flow.

Production Line Integration
The continuous conveyor design allows the machine to be installed downstream of filling, sealing, packing, or other packaging equipment for automatic final product inspection.

Up to 80 pcs/min
Supports a specified maximum inspection speed of 80 pcs/min, with conveyor speed adjustable from 20–90 m/min.

≤3000 g Weighing Range
Supports individual product weights of up to 3000 g, with customization available according to production requirements.

±0.3 g to ±1 g Weighing Accuracy
Provides dynamic weighing accuracy of ±0.3 g to ±1 g, depending on product and operating conditions.

0.1 g Minimum Division
The weighing system provides a minimum division of 0.1 g, supporting precise package-weight inspection.

Adjustable Metal Detection Sensitivity
Detects ferrous contaminants with a specified sensitivity of ≥1.0 mm, Cu sensitivity of ≥1.5 mm, and stainless-steel sensitivity of ≥2.0 mm under the documented configuration.
