# Output voltage of Crystal Oscillators

I am currently building a circuit that produces a 200khz signal with a potential difference of 3 - 12 volts, depending on the force applied to a strain gauge. The input voltage is a 12V, 50hz source. With no force applied to the strain gauge, the output is to be 3V and 12V at breaking force.

From my research I discovered that I can use a crystal oscillator to produce the 200khz signal, except I am having trouble understanding exactly how the component works and its output voltage. Should I convert the input voltage to DC, then run it through the oscillator and the voltage of the input DC will be the voltage of the 200khz signal produced by the oscillator? That is, is the voltage input the same as the output (perhaps a small decrease due to the resistance of the component) across this component?

It's not what you think. It's more like a high-Q RLC resonator. It doesn't do anything unless you connect it to the right kind of amplifier. The whole thing is then a 200KHz oscillator.

What is the standard price range on these amplifiers, and once I connect the oscillator to the aforementioned amplifier, how can I determine the output voltage? Or alternatively, is there an easier way to convert the 50hz signal to a 200khz signal?
