Connection and Wiring Guidelines
Load Cell
A load cell based on strain gauge sensors is basically a full wheatstone bridge which is specified by its voltage sensibility in [mV/V] of the applied excitation voltage and the load sensibility in [Applied Load/Rated Load].
The SGA-2 Amplifier can be connected either in 4- or 6 wire mode:
The 6-wire mode compensate any voltage drops on the excitation voltage line between the amplifier and the sensor/load cell.
Formulas
Vout[mV] = G * Vex[V] * Sensitivity[mV/V] * Load/(Rated Load)
Load = Vout*(Rated Load) / (G * Vex * Sensitivity)
where:
- Vout = Output Voltage of the Amplifier
- G = Amplifier Gain
