VBOX Strain Gauge Amplifier (SGA02)
SGA02
●Dual-channel
●DC isolated channels
●90 dB typical CMRR
●Adjustable gain from 25 to 1000
●Amplifies strain gauge signals to a usable analogue voltage for a data logger
Overview
The Racelogic Strain Gauge Amplifier (SGA02) amplifies the differential signals of a strain gauge to provide a sufficient analogue voltage input for a data logger. It has two user-adjustable channels.
Each channel is DC isolated and designed for full bridge operation, but can be adapted for half bridge and quarter bridge applications.
The output range of each channel is ±9 V, with input signal gain adjustable from approximately 25 to 1000.

Connection
Wires connect to the amplifier via screw terminal contacts for simple fitting.
Wires can be run in through the three mini cable glands, so the lid can be replaced and the internal screw terminals and the scale and offset adjustment screws stay covered.
When used with a full bridge load cell, no additional equipment is required.
