Overview
Pulsotronic-Anlagentechnik GmbH provides a tunnel detector, Type TU – Digital 2 / M-Pulse2pro, designed for retrofitting metal detectors on existing lines and mounting on conveyor belts and chutes. The sensor is made entirely of stainless steel, making it suitable for use in both the plastics and food industries.

Specifications
The TU sensor offers high sensitivity for metal detection and can distinguish between signals caused by vibration, product, or metal. It is maintenance- and calibration-free, enhancing its usability across various applications.

Functionality
The device operates using a system of three coils, allowing precise signal analysis. Handling is facilitated through a membrane keyboard and LC-display, enabling easy adjustment of sensitivity and other parameters.

Mounting
The sensor's sensing range extends above and below the detector's opening, requiring metal-free zones to ensure accurate functioning. These zones are categorized into those for movable and non-movable pieces, with dimensions specified in data sheets.
