Racelogic's Strain Gauge Amplifier (SGA02) increases the differential signals of a strain gauge to enable a sufficient analogue voltage input for a data logger. It comes with two channels and is user adjustable.
Each channel is DC isolated and designed for full bridge operation, but can be adapted for use in 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.
Wire connection to the amplifier is via screw terminal contacts for simple fitting.
Wires can be run into the Strain Gauge Amplifier using the three mini cables glands. This allows the lid to be replaced, enabling secure connections to the internal screw terminals without leaving them or the scale and offset adjustment screws exposed.
When using the Strain Gauge Amplifier in conjunction with a full bridge load cell, no additional equipment is required. Simply connect the load cell to the Strain Gauge Amplifier as shown in the diagram below.
