Cobra4
New members of the Cobra4 family – extended opportunities for experimentation during your classes Cobra4 Sensor-Unit Energy: current, voltage, work, and power
Features
This sensor unit enables numerous fundamental and application-relevant experiments, e.g. concerning the characteristics of AC resistors or the energy demand of consumers.
Measurement and direct indication of measured quantities concerning the electrical power and energy in AC and DC circuits (current, voltage, active power and apparent power, phase shift, frequency, and electrical work) Can be connected to a Cobra4 Wireless-Link, Mobile-Link, USB-Link, or Junior-Link Technical data: Measuring range and resolution: 30 V (0.3 mV), 6 A (0.3 mA) Frequency range: up to 2 kHz
Cobra4 Sensor-Unit Spirometry: respiratory volume, wind speed
Features
This sensor unit enables the measurement of spirograms that can be used to determine the various functional quantities of the respiratory volume. In addition, the wind speed can be measured.
The Cobra4 Sensor-Unit Spirometry is used to measure the respirationdependent lung volume Measurement of the wind speed possible Can be connected to a Cobra4 Wireless-Link, Mobile-Link, USB-Link, or Junior-Link Technical data: Measuring range (accuracy): -15 … + 15 l/s (3%) Max. data rate: 5 Hz Volume: -15, ..., + 15 l Volumetric flow rate: -10, ... , + 10 l/s Wind speed: 0.2, ..., 20 m/s
