10-bit (±1V) Voltage Input Phidget - VCP1002
10-bit (±1V) Voltage Input Phidget - VCP1002
Measure tiny voltage differences of up to ±1V with precision. This Phidget is isolated and plugs into a VINT port.
This Voltage Input Phidget provides a way to measure small voltages anywhere in a circuit. It plugs directly into a VINT port and has a set of selectable voltage ranges from ±1V down to ±10mV, with smaller ranges having higher precision (See the "Compatible Products" tab for a list of VINT Hubs). This Phidget also has an automatic mode that continuously adjusts the range based on present voltage measurements, so you'll always have the most accurate measurement possible.
Ideal for Use with Current Sense Resistors
You can use this Phidget to measure current in a pinch: Just place a known resistor in series with the circuit, and measure the voltage drop across it. Knowing the voltage and resistance, you can then use Ohm's law to calculate the current.
Isolated for Stability
This Phidget is electrically isolated, so a power surge on the circuit you're measuring will not damage your VINT Hub or your computer. Isolation also improves stability by eliminating potential ground loops.
