THS/TT

CEIA THS/TT Metal Detectors, designed for operation in high speed production lines, allow interception of all magnetic and non-magnetic metals, including high-resistivity stainless steel. The system is composed of an electronic control unit and an antenna which is positioned in the path of the product to be inspected.

The advanced antenna design, completely manufactured in AISI 304 Stainless Steel, ensures high stability, high immunity and exceptional reliability.

DSP (Digital Signal Processing) of the Metal Detector Antenna signals allows a very high degree of sensitivity to be achieved for all metals.

Microcomputer control and complete programmability simplify installation, and in certain applications can offer the capability of operating as production line controller using suitable sensors and actuators.

Modern, rugged and user friendly programming
