Vernier CRG-BTA Charge Sensor
Vernier CRG-BTA Charge Sensor Description
Unlike a traditional electroscope, the Charge Sensor can make quantitative measurements. Numerical measurements improve many electrostatics experiments, such as charging by induction, charging by friction, and charging by contact.
The sensor can also be used to measure charge polarity. An extremely high-impedance voltage sensor with a 0.01µF input capacitor makes these measurements possible. The sensor has three operating ranges and a zeroing switch to discharge the input capacitor.
± 0.5 V (± 5 nC)
± 2 V (± 20 nC)
± 10 V (± 100 nC)
Maximum input: ± 150 V
Typical bias input current: 0.005 pA
Input capacitance: 0.01 µF
Instrument time constant: 0.1 s
Vernier Charger Sensor
Low-leakage BNC/Alligator Clip Cable
The Charge Sensor requires a compatible interface and software to collect data. Interface and software sold separately.
The Charge Sensor is compatible with these interfaces:
NXT Sensor Adapter
TI-Nspire Lab Cradle
