Transmission Line Probes
-
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 1kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.

ElektroPhysik Dr. Steingroever GmbH & Co. KG
Measuring the lining thickness of rotary kilns is an important process in the industry, especially in cement production. The lining of a rotary kiln consists of refractory material that has to withstand high temperatures and chemical stresses to ensure a smooth production process. The thickness of the lining is of great importance because it has a direct influence on the efficiency, safety and service life of the rotary kiln. Measuring the lining thickness is therefore an important and fundamental aspect when it comes to the safety of rotary kilns.
