Hawk MeasurementHawk Measurement has added a new firmware program to help simplify the calibration of the fourth generation Acoustic Technology of the Sultan Acoustic Wave Level. This will allow for up to 22 different applications as diverse as ROM Bins, process slurry sumps, primary crushers, stockpile monitoring and positioning that can start up with a minimum of adjustments. Converting the AWR234SUXXXX Remote Sultan transmitter from a three-to-four wire AC/DC supply to a two-wire, loop-powered 24vdc supply sometimes meant calibration changes to the transducer, but this is now automatically calibrated with the new firmware upgrade. – hawkmeasure.com
