DISPLACEMENT TRANSDUCERS
T-NC/8-API The T-NC/8-API transducer measures the distance of a ferrous material from
the sensor head. The non-contact type measurement can be both dynamic for vibration measurement and static for displacements.
The measuring chain is composed by a proximity sensor, an extension cable and a converter.
The converter is inserted in a box and contains the electronics to power the sensor and
signal linearization. The operating principle is based on the generation of a high-frequency
electromagnetic field irradiated by the sensor which induces an eddy current in the target. The
intensity of this eddy current depends directly on the distance between the sensor and the
target and is converted into an electric signal processed by the converter.
The sensor is composed of a stainless steel body and a Teflon coaxial cable.
