New Adjustable Attenuator for Mining

Adjustable attenuators for mining improve signal control and noise reduction, with solutions available for both RF networks and generator noise management.

RF and Leaky Feeder Applications

The Becker Mining Systems smartcom® 450 In-line Attenuator is designed for mining communication networks, particularly Leaky Feeder systems. It allows precise adjustment of signal loss at any point along the network, improving voice and data performance by reducing system noise and maintaining minimal losses between components such as line amplifiers and Ethernet devices. The device features a single PCB housed in a glass fiber reinforced polyester enclosure and includes two RF connections for easy installation with UHF coaxial radiating cables . Mini-Circuits also offers digital step attenuators (DAT series), which provide adjustable attenuation from 0 to 15.5 dB in 0.5 dB steps. These devices use a CMOS process for high performance and can be controlled via a 5-bit serial/parallel interface, making them suitable for precise RF signal management in mining communication systems .

Noise Management for Mining Equipment

For generator and machinery noise reduction, Minetek provides generator attenuators that target both low-frequency exhaust noise and high-frequency radiator fan noise. The exhaust system uses dual-skin mufflers, flexible bellows, and pipework to absorb engine noise, while the radiator attenuator incorporates sound-reduction media to minimize fan noise without restricting airflow. These solutions can reduce noise levels by up to 50%, enhancing operator safety, regulatory compliance, and community relations. Minetek's attenuators are compatible with a wide range of mining equipment, including haul trucks, excavators, dozers, and generators .
