The 1121 provides an interface to non-Phidgets resistance sensors such as: Force-Sensing Resistors (FSR), light sensors, thermistors (heat sensors), and bend sensors.
The 1122 measures AC current up to 30 Amps and DC Current from -30Amps to +30Amps. Dual outputs allow the user to measure both the AC and DC components of complex current waveforms separately.
The Voltage Sensor measures the differential voltage between the input terminals and outputs the difference proportionally. The maximum differential voltage that can be measured accurately is ±30V.
