Bently 330180-50-00
Product Introduction:
The 330180-50-00 is the signal-conditioning module that converts the high-frequency eddy-current signal from the probe into a calibrated DC voltage proportional to gap. It forms the “driver” half of the 3300 XL 8 mm proximity transducer system and is mounted in the instrument cabinet rather than on the machine.
