The Count/Tachometer adapter counts electrical pulses. It contains the calibration for 11 different ranges making this a very versatile sensor for a wide range of investigations.
The Count/Tachometer Adaptor can count up to 60,000 cumulative events or the speed of a rotating bicycle wheel. It can be used to investigate Newton’s laws with Atwood’s machine or count red and green buses, anything where you count an event or use events per unit of time for rate e.g. revs/second, miles per hour, rpm, counts /second.
Students can study weather patterns with our environmental accessories; by recording wind speeds with our Anemometer or the amount of rain fall over time using our Rain Gauge.
Atwood’s machine provides a simple and economical way of testing Newton’s 2nd Law. Find the accelerating force by recording the difference between the weights of the two masses hanging either side of a free running pulley.
All our sensors come with 5 years warranty and lifetime support, we ensure your investment gives you complete peace of mind.
The Count/Tachometer adaptor is pre-calibrated at manufacture making it ready to plug-in and start using with minimal setup time. Here's a selection of experiments you can achieve by using the Count/Tachometer adaptor, additional accessories are required.
|Measure the distance and speed of a road bicycle|
|Record wind speed using an Anemometer|
|Record rain fall using a Rain Gauge|
|Get distance measurements from a spoked pulley|
|Study circular motion|
|Use with switches to count events|
|Muscle fatigue using a Light gate|
|Bike speed and exercise|
The Count/Tachometer is supplied as a single adaptor item and designed to be used with other sensors such as an Anemometer or a rain gauge.
For customers outside of the UK, please contact Data Harvest or an overseas distributor within your country.
