SGA-2
Bridge Amplifier for Strain Gauges
The SGA-2 bridge amplifier is designed for highly dynamic measurements with strain gauges.
Strain gauges can be connected in full bridge, half bridge or ¼ bridge configuration. Two independent channels are available per amplifier module. To compensate for voltage losses in the supply line, the 6-wire technique can be used. In the gain stages x1 and x10 the bandwidth is 1.5 MHz
For configuration of all settings and for monitoring of a static output signal the USB / RS458 interface can be used.

Variants
Rack-Version
- 2-channel plug-in module SGA-P/7 or SGA-P/16
- Amp-BU-10 (for up to 5 modules / 10 channels)
- Amp-BU-24 (for up to 12 modules / 24 channels)
- USB connection on the rack for operating all plug-in cards (internally via RS485)
Box-Version
- 2-channel Module SGA-Box/7 or SGA-Box/16
- USB port (emulated COM port)
- External power supply
Rack Variant
The SGA is available as a rack-mountable module and can be installed in a rack for 5 or 12 modules:
- Amp-BU-10 (for up to 5 modules / 10 channels)
- Amp-BU-24 (for up to 12 modules / 24 channels)
The advantage of the rack version is the compact design for multi-channel applications. In addition, all channels can be configured via one USB interface.
