Load cell manufacturer introduces a new system that monitors the tension in chains used in conveyor belts

STRAINSTALL have launched a new chain tension monitoring system that provides data on the tensions in chains used in industrial conveyor belts. Should the loads reach pre-set limits, the system has the facility to decrease/increase tension in the chain, trigger alarms to warn operators to take corrective action before any breakdown occurs or stop the conveyor. This avoids the possibility of chain failure resulting in machine downtime, which is crucial, as any machine stoppage holds up production and is extremely costly.

The monitoring unit utilizes proven Strainstall load pins or compressive load cells (depending on the application) to measure the tension in the conveyor drive chain, with the resulting data transmitted to an electronic display.

Specifically designed to operate in extreme temperatures and resistant to high moisture levels, abrasive materials and vibration, both the load pins and load cells are suitable for use in the harsh conditions found in the mining, marine and quarrying industries. The load pins are also resistant to the effects of metal fatigue, a condition caused by being subjected to repeated cyclic loads.

Custom-designed software and a range of display options are available on the monitoring system to meet the needs of individual customers. Key features and benefits include: maximized chain life; reduced maintenance requirement; ATEX/IECEx certified for use in Zone 1 and Zone 2 hazardous areas; and increased reliability and productivity.

Adrian Coventry, engineering director at Strainstall, said: ‘This new system means conveyor operators no longer have to worry about chain overloading and potential system failure, which has the additional benefit of providing significant cost savings from both improved operation and increased chain life. Also, as it uses our load cells and pins that have many years of proven use in harsh environments, they are can be assured our system will provide a long-term, hassle-free operation.’
