Load Cell Integrity Junction Box & Fault Monitoring Alarm

Product catalog summary
Product Features
  • Increased Safety: The LCI provides fault monitoring capabilities that ensure a safe working environment by continuously sampling load cell channels.
  • Cost and Time Savings: Immediate alarm and fault diagnosis reduce downtime.
  • System Protection: Prevents material shortage, overflow, or incorrect batching due to load cell damage or cable faults.
  • Low Power Consumption: Available in 5V excitation, requiring less power.
  • Installation and Commissioning Aid: Simplifies setup processes.
Introduction

The LCI load cell failure alarm is designed to monitor individual load cells continuously and activate an alarm upon detecting faults, enhancing safety and cost efficiency for weighing systems. It supports both 5V and 10V operations, with 5V reducing power consumption and simplifying barrier selection. It is ideal for multi-load cell installations like silos and tanks, where individual load cell failure can lead to significant issues.

Load Cell Integrity Junction Box & Fault Monitoring Alarm-1

LCI Load Cell Integrity Junction Box & Fault Monitoring Alarm , Introduction r i Product Features • Increased Safety: Fault monitoring capabilities provide a safe working system in critical applications by continuous sampling of load cell channels • Cost and Time Savings: Reduction of down-time via immediate alarm and fault diagnosis • System Protection: Avoids material shortage, overflow, or incorrect batching due to load cell damage or cable faults • Low Power Consumption: Now available in 5V excitation which requires less power • Avoids batch wastage and product recall • Aids installation and commissioning The LCI load cell failure alarm is designed to continuously monitor the condition of individual load cells and activate an alarm when faults in the system are detected, therefore providing increased safety and cost savings onsite for all weighing systems. The latest version of the LCI now supports both 5V and 10V operation. 5V operation requires less power consumption from the connected instrument and simplifies barrier selection. It provides protection for multi-load cell installations such as silos, tanks and other systems where the failure of an individual load cell can have serious consequences such as material shortage, overflow, or incorrect production batching. The device constantly samples the individual load cell channels and activates an alarm if any failure conditions are detected, ensuring a safe working system. The LCI should be used in conjunction with a host intelligent weighing instrument such as Mantracourt's ADW15, LCA20, LCD20, SMW etc. as well as suitable third-party products.
