About the Metal Detector Range

Introduction

Loma’s metal detectors are packed with some incredible patented innovations, which are all designed
to make them compliant with current legislation and best in class.

Even more robust and reliable, the latest products continue to lead the way in tackling key industry
challenges and standards, notably food inspection Codes of Practice and user traceability. Its
breakthrough innovations, including a new touch screen display, can be easily retrofitted to older
product versions on request.

The search head is available separately for fitting to your own conveyor or this can be supplied as a
system, already fitted to a Loma conveyor. A Pipeline Metal Detector is also included in the range for
inspecting pumped products.

The items numbered in the figure are listed and described below.
