CD15 General Purpose Basic Carrier Demodulator
- Output: ±10 Vdc
- Compact: may be used on bench top or mounted in existing enclosures
- Regulated against line voltage variation
- Fast Dynamic Response
- Solid state reliability
Basic Signal Conditioner for Variable Reluctance Transducers.
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.
The unit is small enough to be included in the case of most receiving and recording instruments.
