FUNCTION The T-NC transducers detect the displacement of a target facing to the probe. The different dimensions of the probe allow its application for the detection of different measuring ranges. They are powered at 24 Vdc and provide a 0-M0 Vdc or 4-^20 mA signal proportional to the displacement.The transducer is used for no-contact measurement of displacement and expansion of rotating machines. The probe structural features allow its installation in a particularly heavy environment, with the presence of steam, oil and aggressive agents (typically on steam turbines, gas turbines, compressors, etc.). GENERAL DESCRIPTION These transducers are composed of a ST-NC/16, ST-NC/20 or ST-NC/30 probe and a CT-CN converter contained in a die-cast aluminium housing, complete with a connector (according to MIL standards) for the connection of the transducer to the acquisition system. The principle of operation is based on the generation of an electromagnetic high frequency field, radiated by the probe, which induces an eddy current in the target. The intensity of this eddy current depends directly on the distance between probe and target and it is converted into an electrical signal processed by the converter. The probe consists of an AISI 304 stainless steel body and it is supplied with a coaxial teflon cable. The converter is manufactured with microprocessor technology to ensure measurement linearity and precision. The generated electrical signal, depending on the distance between probe and target is opportunely linearized during the transducer calibration phase. It is supplied calibrated foreseeing the AISI 4140 target (calibration with different targets are available on request). CEMB BALANCING MACHINES
