Structure and mode of operation
PW15iA digital load cells are part of the family of elec
tronics developed by HBM for static and dynamic weigh
ing processes. The measuring element is a steel loaded
member to which strain gages (SG) are applied. The SG
are arranged so that two are stretched and the other two
compressed when a load acts on the load cell. The
PW15iA digitally conditions the signals and delivers a
fully-filtered, scaled and digitized output signal for direct
connection to bus systems or PCs via the RS‐485 inter
face, CANopen, or DeviceNet. Measuring element and
electronics are housed in a single enclosure. The digital
load cells can be quickly and easily matched to a particu
lar system by various parameters, and they work with an
internal data rate of up to 1200 measurements per sec
ond.
The inbuilt digital inputs and outputs allow event-driven
weight determination, e.g. for checkweigher applications
or dosing controls. The digital outputs can be configured
by software command, and can be used to control coarse
flow and fine flow in dosing valves, for example.
The
PanelX
PC software is available to facilitate parame
ter settings, to display dynamic measurement signals and
for comprehensive frequency analysis of the dynamic
system.
This document describes the installation and functions of
the digital load cell. The commands for the interfaces can
be found in the online documentation for the PanelX pro
gram.
