Conveyor Belt Misalignment Switch

SRT Conveyor Belt Misalignment Switch

Overview

This device monitors the operation process for potentially hazardous conditions and activate an alarm when it is occurred misalignment, the SRT series conveyor belt misalignment switch protects the conveyor belt from damage due to belt misalignment or run off。For normal condition, the belt misalignment switches are generally mounted on both sides andthe edge of the conveyor belt。

A small clearance between the contact rollers and a little swaying for the belt edges are allowable. When the swaying exceeds the normal limit (on/ about 20 mm), the belt edge pushes the contact roller, which drives the switch and operates the contacts, the misalignment switch will reset automatically when the belt resumes normal running.

These control devices are used in pair on both side of conveyor belt detected place, each unit can be equipped with two micro-switches to produce signals indicating the belt misalignment at two deviation points。

The first signal point could indicate small belt deviation by output an alarm, the second signal point could guard against extreme belt run off by shutting down the conveyor。

The roller is adjustable up to 20° in both directions and is positioned approximately 20mm from the conveyor belt, the switch actuation points are adjustable from 0 to 35° by a simple change of the actuating cams。
