High Current Sensor

The Differential Voltage Probe is designed for exploring the basic principles of electricity. Use this probe to measure voltages in low voltage AC and DC circuits. With a range of ±6.0 V, this system is ideal for use in “battery and bulb” circuits. Use it with the Current Probe (DCP-BTA) to explore Ohm’s law, phase relationships in reactive components, and much more. Use multiple Differential Voltage Probes to explore series and parallel circuits. The Differential Voltage Probe reports the potential difference between the red and black leads. For example, if the black terminal is attached to something that is 2 V above ground, and the red to something that is 3 V below ground, it will report -5 V. The Differential Voltage Probe is the preferred voltage sensor in cases where more than one voltage sensor will be used in the same circuit. Input voltage range: ±6.0 V Maximum voltage on any input: ±10 V Input Impedance (to ground): 10 M Ω Differential Impedance: >20 M Ω Typical Resolution: 3.1 mV user manual

The Current Probe can be used to measure currents in low-voltage AC and DC circuits or for electrochemistry experiments. The Current Probe measures DC and low-frequency AC currents up to 600 mA. Use Current Probes in combination with Differential Voltage Probes to investigate Ohm’s Law and explore series and parallel circuits. The 0.1 Ω shunt resistor minimizes changes to your circuit. If currents will exceed 1 A, use the High Current Sensor. Range: ±0.6 A Maximum voltage on any input: ±10 V User Manual

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. Ranges:± 0.5 V (± 5 nC)± 2 V (± 20 nC)± 10 V (± 100 nC) Maximum input:± 150 V Typical bias input current:0.005 pA User Manual

This Voltage Probe can be used with the Vernier LabPro, LabQuest, LabQuest Mini, Go!Link, Easylink, SensorDAQ and CBL 2 to measure direct voltage. The Voltage Probe is a bipolar sensor. The black lead is grounded along with the interface, and the sensor reports the potential difference between the red lead and ground. It can be used to measure the potential in DC or AC circuits. You might also consider the Differential Voltage Probe (DVP-BTA). Multiple Differential Voltage Probes can be connected to a circuit without the use of a common grounding terminal.

The Vernier Energy Sensor offers an easy way to quantify voltage, current, power, and energy output of small wind turbines and solar panels such as those used in our KidWind Experiment Kits. Setting up a circuit to study renewable energy systems such as wind turbines or solar panels is easy with the Vernier Energy Sensor. Simply connect a source such as a small wind turbine or solar panel to one side and a load such as the Variable Load (VES-VL) or a resistor on Vernier Resistor Board (VES-RB) to the other side. The Energy Sensor measures the current and voltage of the system. Data-collection and analysis software, such as Logger Pro or LabQuest App can then calculate the power and energy output. Source Input Potential Range:± 30 V Source Input Current Range:± 1000 mA User manual

Description Simpler to use than a multimeter, the Go Direct Energy Sensor measures the voltage and current oputput of a renewable energy system. Connect a source, such as a small wind turbine or solar panel, and our free Graphical Analysis 4 app displays voltage, current, power, and energy output. For simple energy measurements, Go Direct Energy includes a fixed load of 30 Ω. For more advanced experiments, electrical contacts are built into the sensor to connect to an external load, such as the Variable Load, a resistor on Vernier Resistor Board, a water pump, or lights. The Go Direct Energy Sensor is ideal for a wide variety of renewable energy experiments:  Investigate the electrical energy generated by a wind turbine or solar panel. Explore the effect of load on wind turbine or solar panel output. Test blade design variables and evaluate data to determine optimal blade design.
