Procon Engineering have recently appointed Ultra-Dynamics as their agent for sales and marketing for the Inflo resometric beltscale across Australasia. The Inflo Resometric Belt Weighers provide a unique combination of features that ensure the key factors influencing belt scale performance are maintained in service over long periods.
One of the major features of this scale is the Digital Resometric Force Transducer or Resonator, which provides unequalled levels of measurement performance that are repeatable for many years. The Resonator has no moving parts and is pre-loaded to a standard level by the applied force from the weigh carriage.
The resonant frequency changes in proportion to applied load passing over the carriage rollers. This change in frequency is processed by the electronics and combined with the belt travel speed (as measured by the Tachometer) to provide an accurate weight reading per unit time.
Periodic calibration checks can be carried out by utilising the roll-over calibration weights. These dead weights are normally ‘parked’ across the conveyor stringers and then lowered by a cam mechanism to carry out calibration.
The Inflo Belt Weighers are used in applications, such as custody transfer, ship unloaders and stacker/reclaimers. In these applications, belt weighers are subjected to constantly changing angles of operation which would introduce significant cosine weighing errors due to the apparent change in the suspended weigh carriage mass. Procon’s proprietary technology has overcome these problems.
