Walk-through metal detectors are often divided into multiple detection zones, typically ranging from 1 to 33 zones, depending on the model. Each zone corresponds to a specific area of the body, allowing for more precise localization of detected metal objects.
Walk-through metal detectors usually offer adjustable sensitivity settings to accommodate different security requirements and minimize false alarms. Sensitivity levels may be adjusted based on factors such as the size and type of metal objects to be detected.
Most walk-through metal detectors use electromagnetic induction technology to detect metal objects. Some models may also incorporate additional detection technologies, such as pulse induction (PI) or multi-coil systems, to enhance detection capabilities and reduce interference from environmental factors.
The detection strength of walk-through metal detectors refers to their ability to accurately detect metal objects of varying sizes and compositions. Higher detection strength ensures reliable detection of both ferrous and non-ferrous metals, including weapons, coins, and jewelry.
Walk-through metal detectors typically feature multiple alarm modes to indicate the presence of metal objects. Common alarm modes include audible alarms, visual indicators (such as LED lights), and vibration alerts. Some models may also offer silent alarm options for discreet operation.
The operating frequency of walk-through metal detectors determines their sensitivity to different types of metals and interference from external sources. Most models operate within the frequency range of 1 kHz to 100 kHz, with higher frequencies generally offering greater sensitivity to small metal objects.
Walk-through metal detectors are constructed from durable materials such as stainless steel or aluminum to withstand frequent use in high-traffic environments. They are typically designed to meet industry standards for reliability, stability, and resistance to tampering or vandalism.
Walk-through metal detectors come in various sizes and weights to accommodate different installation requirements and spatial constraints. Portable or lightweight models are available for temporary or mobile security applications, while larger, heavier units are suitable for permanent installations in airports, government buildings, and event venues.
Walk-through metal detectors require power to operate, typically supplied through standard electrical outlets. Some models may also offer battery backup options for continued operation during power outages or temporary installations where access to electrical power is limited.
Walk-through metal detectors may be designed to meet specific regulatory standards and certifications, such as those set by government agencies or international organizations (e.g., TSA, CE, FCC). Compliance with these standards ensures that the detectors meet established performance, safety, and quality requirements.
These specifications provide an overview of the common features and capabilities of walk-through metal detectors. When selecting a walk-through metal detector, it’s essential to consider factors such as detection sensitivity, reliability, ease of use, and compliance with relevant standards to ensure effective security screening operations.
