ROCKBOLT LOAD CELL

Designed for measurement of load on bolts in mines

Operating principle: -

The instrument, which is portable, measures loads on rockbolts.

The load cell is designed for loads up to 20 Tonnes. Load is applied to a cell of a known area, pressure within the cell is transmitted to a pressure gauge. The area is designed to have a 2:1 ratio between load and pressure. The gauge is rated at either 0 to 6 mPa, or 0 to 10 mPa, 1 mPa = 2 Tonnes, 6 mPa = 12 Tonnes etc. Accuracy is +- 5%.

Features: -

1. Simple, reliable and easy to read, with no electrical connections.

· Can be installed by one person.

• 16mm thick load spreader plates on top and base, 200mm diameter.
• Designed with a split centre sleeve, to allow for assembly without removing the rock-bolt nut.
• Mass 8,5Kg.
• List price R3160,00 plus VAT (valid until End May 2017) Quantity discounts will apply.

 Optional extras: -

· Max pointer type gauge, this indicates the peak load reached between observations.

· Add R477,00 plus VAT (valid until End May 2017). NO QUANTITY DISCOUNTS

• Pressure gauge can be replaced by a pressure transducer for remote data logging.

Add R7632,00 plus VAT.

• Gauge armour can be supplied when fitted close to a blast, add R386,00 plus VAT.
