SGABCM Zum Anschluss von 1/2- und 1/4-DMS Brücken

The SGA Strain Gauge or Load Cell Amplifier is a high performance signal conditioner for single or multiple strain gauge bridge sensors (load, force, pressure, torque), offering a wide bandwidth and a wide input signal range.
The device can be powered from AC or DC supplies providing excitation for up to four (350 ohm) strain gauge bridges.
The conditioned output signal can be selected from 0-20mA, 4-20mA, 0-10V, 0-5V, ±5V or ±10V.
Options include: Isolated DC supply, DIN rail mount and OEM-PCB module.


  • Strain gauge amplifier for signal conditioning of load cells
  • Bridge excitation of 5V or 10V DC with drive for four 350 ohms load cells
  • Bridge resistance: min. 85 Ohms
  • Selectable bandwidth of 1 to 5000 Hz (6000 without Filter) for test & measurement applications
  • Selectable sensitivity from 0.06 to 30 mV/V using switches and fine trim potentiometer
  • Selectable offset ±79% FS using switches and fine trim potentiometer
  • User selectable analogue output in standard voltage or current format
  • The SGA comes complete with a waterproof IP65 / NEMA4 case.
  • An OEM-PCB-Version is also available
  • Available with AC or (isolated) DC power supply options
  • Robust and Fully CE compliant

NEW MODULE AVAILABLE for 1/2 or 1/4 Bridge Connection (SGABCM):

  • Provides local and remote shunt calibration
  • Supports 1/2 and 1/4 bridges
  • High stability resistors
  • Compatible with all variants of the SGA
  • Easy installation
  • Retro fit PCB also for existing installations

For a digital version with set point relays, serial communications and display options please see our Load Cell Amplifier Model LCA20.
