Proximity sensor no contactThe 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 Proximity sensor is composed of an ST-NC/8 proximity sensor, a CPT-NC/8 extension cable and a T-NC-8/API converter.
The generated signal allows measurements of vibration, displacement, eccentricity and speed in the specific application.
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
It is manufactured according to API standards and it is available also with different certifications: intrinsecally safe Atex, TP TC, IEC EX.
