Hopper level monitoring

Traditionally it has been very hard to measure solid level in ore hoppers with 2 wire radar. This is due to the fact that the surface is sloped and irregular, and the dielectric of the product is very low. This would yield very noisy and weak signals and would require expensive high power radars to yield better signal returns. Another key challenge is the rapid level changes from trucks dumping and ore dumped in crushers.

Current software improvements to Rosemount 5400 yield better signal strengths and improved performance in the measurement of solids. The footprint for this technology is much smaller than the traditional parabolic antenna, making installation easier and more cost effective. The added value to the Rosemount 5402 is the much lower cost than the high powered 4 wire radar.

With the Rosemount 5400, maximum mounting and application flexibility is ensured with a wide range of antennas and two models with different microwave frequencies, 5401 (6 GHz) and 5402 (26 GHz). Dual Port Technology enables a stronger signal than other 2-wire radar transmitters, providing better measurement reliability.
