TruSense® Laser Sensor is Seeing Copper

By Kharrold, 11/12/14 

A copper mine in Utah is using Laser Tech’s non-contact, continuous level measurement TruSense® laser sensor to ensure their froth floatation tanks maintain the proper levels.

Customized installation of the sensor as a component complies with the safety regulations of the plant and guarantee protection of the sensors in this harsh environment.

TruSense Laser Sensor In Use At Copper Mine

A ruggedized enclosure, as seen in the photo below, mounts with the laser sensor at the top of the tanks. Each resides next to the air downcomer center and faces the recirculation well. The mine decided to use TruSense laser sensors because of their 4 – 20 milliamp (mA) capability. As the sensor measures distance, it outputs between 4 and 20mA in relationship to the distance. The sensor outputs 4mA if set to measure the shortest distance. When set to the longest distance, it outputs 20mA. 

The sensors integrate into the plant’s control system and feed live data the master control room for monitorization. This central monitoring enables the operators to watch over several tanks at once along several other advantages: 

The splash tube, seen below the ruggedized housing,  prevents any splashing of the froth or liquid onto the sensor housing lens. This design ensures accurate, maintenance-free operation. The durable TruSense will provide years of trouble-free operation for the copper mine.
