Frequency-To-Voltage Converter Ectron Model 441A

Frequency-To-Voltage Converter Ectron Model 441A produces an analog output that precisely represents the frequency of an applied input signal. Adjustable"input frequency to output voltage" set points allow the user to closely bracket the frequency of interest.

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
