1054 - Phidget Frequency Counter
All prices are VAT included
Product Features
- Measures the frequency of an analog or digital signal
- Measures zero-centered signals with a minimum amplitude of 110mV peak-to-peak
- Measures logic-levels (3.3V and 5V)
- Connects directly to a computer's USB Port
Product Description
the 1054 - PhidgetFrequencyCounter is designed to count events from an analog signal over time and calculate a frequency from it. The product can count a logic level or signal centered around zero volts. Signals with a different ground can be counted, provided they are within the common mode range (+-10V).
The Frequency Counter can also power small devices, such as Hall Effect, flow rate sensors, tachometers, and other sensors.
The PhidgetFrequencyCounter contains two channels to sense two different inputs. Each channel has two different circuits to sense for logic level-frequencies or zero-centered frequencies. The measurable frequency is accurate to 0.25% up to 1MHz. The Frequency Counter may measure frequencies past 1 Mhz, but the input voltage specifications will not hold.
The PhidgetFrequencyCounter can measure frequencies down to ~ 0.01Hz. However the response time of these measurements is directly related to the frequency, thus it could take 1 or 2 periods(100-200s) to detect the input frequency.
Comes packaged with
- A 193018 - Mini-USB Cable 180cm
- A Hardware mounting kit (4 nuts and bolts, 4 plastic spacers)
