Frequency-To-Voltage Converter Ectron Model 441A
![]() A unique crystal-controlled microcontroller design provides fast response, high conversion accuracy and low output noise that is independent of frequency. The font-panel display shows the input frequency with up to five-digit resolution. All operating parameters are set using the display and one other front-panel control. The input signal conditioner automatically provides stable operation for a wide range of pulse-, square- and sine-wave signals from under 10 millivolts to 100 volts in amplitude. Three selections of input sensitivity and input bandwidth are provided, plus a unique digital periodic filter that cancels unwanted output variation caused by an input signal whose frequency varies in a periodic manner. Features: • 1 Hz to 50 kHz Frequency Range • Fast Response • Crystal-controlled Accuracy • Digital Periodic Filter • Adjustable Input Sensitivity and Filtering • Front-panel Display of Frequency to 5 Digits • Precise Control of Output Voltage vs. Input Frequency • Automatically Accepts 10 mV to 100 V Input Signal Range • Output Noise Independent of Frequency Applications: • Engine Monitoring • ABS Evaluation • Cruise-control Test • Drive-line Analysis • Overspeed Monitor/Control • Failure Analysis • Governor Studies • Flow Meters ![]() |
