Research and Development Background

Currently, most explosive devices are detonated and controlled by electronic devices and electronic timers. Therefore, nonlinear node detectors are widely used in railways, airports, customs, high-level meetings, large-scale exhibition venues, and other places to detect electronic detonators and to conduct explosives safety checks.

However, traditional nonlinear node detectors may result in false alarms in special circumstances, requiring security personnel to carry electronic listening devices for secondary inspection. This leads to issues such as heavy workload, low efficiency, and inconvenient operation.

As a result, composite security detector integrating the functions of nonlinear node detection and electronic listening devices has emerged.

Design Principle

The functional design of the composite security detector integrates electronic listening devices and nonlinear node detectors, allowing for accurate and convenient detection of electronic timed detonators, mechanical timed detonators, electronic eavesdropping devices, and recording devices hidden under various types of packaging and covering materials.

Key Features

Can detect semiconductor nodes and corroded metal nodes

Can detect the working status of mechanical and electronic timed devices

Can detect electronic devices containing semiconductor components in both working and non-working states

Can detect the characteristic sounds of mechanical and electronic timed devices through headphones

Integrated design of the entire machine, with operation interface integrating both electronic listening and nonlinear node detection functions for convenient use

The electronic listening and nonlinear node detection functions can run independently or simultaneously

Equipped with low voltage alarm function (meeting the requirements of GA 1236-2015 "Nonlinear Node Detectors" 5.2.2)

Highlights

【Multifunctional】 Integration of nonlinear node detection and electronic listening functions for simple operation

【Lightweight】 Weighs less than 1.5kg, making it more lightweight than similar products

【Strong Performance】 Large detection distances for both nonlinear and listening functions, exceeding 15 meters

【Quick Response】 Alarm response time for both nonlinear and listening functions is less than 0.2 seconds

【Long Endurance】 Continuous detection time is not less than 6 hours

Application Scenarios

1.Widely used in security, public security, anti-terrorism, explosion prevention, military, airports, stations, ports, and other security inspection places, serving as an important tool for counter-terrorism and explosive detection.

2. Widely used in indoor enclosed spaces such as conference rooms, offices, and residences, as a powerful tool for detecting eavesdropping devices and recording devices.
