Abstract :
A compact impedance spectrum analyzer has been developed that is well suited for the use in process control. Various sensor elements connected to the sensor electronics allow an adaptation to different measuring applications. Digital signal processing minimizes the insertion of noise and distorting effects to the system. Facilities are provided to calibrate the sensor with a reference.
