Temperature control, using a thyristor from Eurotherm

Temperature monitoring, using S-Products temperature transducers

 The Perth Mint is Australia’s oldest operating Mint and one of the oldest still operating from its original site, established in 1899 to mint gold sovereigns for the British Empire. The Mint is owned by the Western Australian Government and is Australia’s specialist precious metals mint, producing collector and investment coins for world markets.

It specialises in precious metals minting in both proof and uncirculated (bullion) qualities, producing regular issues in gold, silver, platinum and palladium.

The existing control equipment for the continuous caster are old and the control requires upgrading with better operator interface facilities.

Industrial Automation is to design, supply and commission the control cubicle containing all control equipment. This includes the supply and design of the control system using a PLC, Operator Interface Panel and thyristor.

It also includes for the supply, installation and calibration of the temperature and current transducers.

Mitsubishi FX2N series PLC

10.5" colour touch screen operator interface, QuickPanel from Total Control

Thyristor from Eurotherm

S-Products temp. transducers

Faget current transducers

IA signal isolators - IA1400

The new thyristor and control equipment is packaged into one control panel which is mounted close to the caster.

The new system facilitates the operator with online status of the operation of the caster. It enables the operator to change system settings with a touch.
