Signal Conditioners / Amplifiers for AC LVDT Sensors
Compact Size | Economical | Precise
These Signal Conditioners have been designed to accept AC LVDTs of any standard make or model and are suitable in many different applications. They incorporate sinusoidal excitation oscillator, signal amplifier, phase sensitive demodulator, low‐pass filter. An output scaling stage amplifier is also integrated to provide voltage or 4 to 20 mA output proportional to the core‐rod displacement of the connected LVDT. A LVDT Amplifier is a necessary requirement for operating AC LVDT.
