BG5K Fabric Belt Rip Detector
The Belt Guard BG5k ultrasonic rip detector is an inexpensive non-contact solution to detecting rips using a change of belt width coincident with a rip. The device is not belt manufacturer dependent and requires no embedded loops or antennae installed in the belting.
The tear detector is designed to be installed after each load point and can be connected to sites’ network via 4-20mA outputs and/or via TCP/IP.
Key Features
- Non-contact detection: Uses ultrasonic monitoring for belt width measurement
- Universal compatibility: Works with any belt manufacturer and any belt type
- No installation required: Requires no embedded loops or antennae in belting
- Flexible positioning: Can be installed after each load point
- Multiple output options: 4-20mA outputs and/or TCP/IP connectivity
How It Works
The Belt Guard BG5k provides a non-contact method of detecting a longitudinal rip in conveyor belting by monitoring the width of the belt. Two ultrasonic probes constantly sense the belt edges. When a rip occurs, the torn sections move apart, causing the belt width to change. The device generates a signal that energizes the HALT RELAY, allowing integration with conveyor control systems.
Belt Tracking / Wander Capability
An additional powerful feature of the BG5k is its Belt Tracking or Wander measurement capability. Tracking the lateral movement of the belt on its structure is vital where product spillage is an issue.
- Sensitivity: Can sense lateral movements of less than a millimeter
- Early warning: Detects belt wander trends early
- Real-time adjustment: Allows sites to change operating parameters to minimize product spillage
- Preventive maintenance: Helps avoid belt damage and operational downtime
