Working Principle - OHAUS Defender Serie Bedienungsanleitung

Defender Series Floor Scale EN-5
DFL series clamshell floor scale are made up of components demonstrated
above. Connect the double shielded cable to the weighing instrument and turn
on the power to use. In addition, external devices such as big screens,
computers and printers can be connected to the scale.

2.2. Working principle

Put an object on the weighing platform. Under gravity, the load cell elastomer
deforms and makes the impedance of the strain gauge bridge adhered to the
elastomer by the strain gage out of balance. As a result, a voltage signal
proportional to the weight value is outputted. The signal is then amplified by a
linear amplifier, and converted to a digital signal by an analog-to-digital
converter, which is processed by the microprocessor of the meter to display
the weight data. Squadron staff can read the weight directly and print weight
record at any time if having a printer. You can open the scale to flush the
hidden areas at the bottom when clean.
