2 Definitions
Measuring uncertainty: Each measuring device has some inaccuracy, but
however, inaccuracy is in a small, defined range of tolerance. This deviation of the
measuring value referring to the effective value is called measuring uncertainty.
Measuring accuracy: Its behaviour is the contrary to the measuring uncertainty:
Increases the uncertainty, decreases the accuracy, and also in reverse mode.
Force measuring bearing: Measuring device using strain gauges, which converts
the load of the measuring roller into electric signals.
Proxy switch: Inductive distance sensor which is used for gearless and contact-
less switching
3 System Components
The Belt scale for bulk conveyors BMGZ600A consists of the following components
(refer also to fig. 1):
Measuring roller

For acquisition of roll load and belt speed
 Flat or troughed measuring roller
 Simple mounting also to existing systems thanks to the all-purpose mounting
elements
 All parts are fully zinc galvanized
Evaluation electronic unit
 For excitation of the sensors and amplifying of the measuring signal
 With operation panel for parametrization
 It is possible to connect external displays
 Interface RS232

Interface PROFI-BUS ®
 Some different housings available
 For 1 measuring roller (BMGZ610A/611A) or 2 measuring rollers (BMGZ620A)
 Additional digital inputs and outputs for extended functions such as
proportioning belt weighers, etc. (BMGZ611A)
External display
 Telecounter to show the charge value
 Analogue display to show the actual flow rate
External printer
 For printing of charge values or daily output
 driven by RS232 interface
