LTI's TruSense Laser Sensor is Seeing Copper

A copper mine in Utah is using LTI's TruSense laser sensor to ensure their froth floatation tanks maintain the proper levels. The sensors are mounted in a ruggedized enclosure from LTI, as seen in the photo below, to comply with the safety regulations of the plant and to guarantee protection of the sensors in this harsh environment. The sensors are mounted at the top of the tanks, next to the air downcomer center and facing the recirculation well.

TruSense Laser Sensor In Use At Copper Mine

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. If it is set to measure the shortest distance, the sensor outputs 4mA, and when set to the longest distance it outputs 20mA.

The sensors are integrated into the plant's control system and monitored in the master control room. This central monitoring enables the operators to watch over several tanks at once along several other advantages:

  • Workers do not need to physically examine tank levels, which saves time and increases safety
  • Real-time knowledge of tank levels
  • Instant alarm notification if tank levels rise or fall out of specifications
  • Saves costs, both in manpower and material, allows the tanks to operate at peak performance

The splash tube, seen below the ruggedized housing, is installed to prevent 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.
