Oct 26, 2009 Max distance of 3 m between sensor and capaNCDT 6500 can be bridged without pre-amplifier. If larger distances are required, DL6510 demodulator unit is used instead of standard plug-in module. Pre-amplifier is then connected between electronics unit and sensor, amplifying sensor signal with minimal noise component. Miniature amplifier CP 6001 is used for multi-channel applications without max output requirements, and CPM 6011 can be replaced in existing measurement channel with CP 6001.
