1. Employs dual-channel signal detection circuit merging technology, offering exceptionally high detection sensitivity and product effect suppression capabilities, with wide applications. Features dual-channel signal display; when a metal object passes through, the indicator light displays different sensing intensities based on the size of the metal. Utilizes DDS frequency synthesis, DSP digital signal processing, power amplifier, and other technologies, demonstrating industry-leading technical standards.
2. Employs a dual high-speed digital signal processor design, boasting high detection accuracy and high-speed processing, with product effect adjustment functionality. For example, moist products, sugary products, and salty products can generate metal-like signals for the metal detector, affecting detection results. This function reduces product effects, achieving better detection results.
3. Easy-to-disassemble mechanical structure for convenient cleaning and maintenance.
4. Suitable for use in production lines.
5. Fully welded food-grade 304 stainless steel frame, high-level protective motor available as an option, high IP69 protection rating, suitable for particularly harsh working environments.
6. Alarm methods: Buzzer alarm for shutdown, or optional rejection device.
7. Multiple rejection methods available (push rod, flip plate, air blowing, etc.) to ensure accurate and reliable removal of foreign objects, minimizing material waste.
