Abstract: System and method for measuring a parameter within a well. The method includes connecting a gauge to a first end of a cable and connecting a vector network analyzer to a second end of the cable, lowering the gauge inside the well, generating a signal with the vector network analyzer and sending the signal along the cable to the gauge, sweeping a frequency of the signal within a given range while feeding the signal to the gauge, determining a resonance frequency of at least one sensor located within the gauge, and calculating the parameter from the resonance frequency of the at least one sensor.
