This detector uses an unusual sensor today. The circuit is from an 80s documentation. Its sensitivity is 10 ppm. The transformer has two secondary voltages.
This circuit amplifies signals from 0.5 Hz to 300 kHz. We found it in an old documentation. Equivalent...
In the figure we have a constant current source for Shape Memory Alloy or (Nitinol). The value of...
