EA402 913-402-000-012 proximity measurement system

EA402 913-402-000-012

The TQ402/TQ412, EA402 and IQS900 form a proximity measurement system, from Meggitt’s
vibro-meter® product line. This proximity measurement system allows contactless
measurement of the relative displacement of moving machine elements.
TQ4xx-based proximity measurement systems are particularly suitable for measuring the relative
vibration and axial position of rotating machine shafts, such as those found in steam, gas and
hydraulic turbines, as well as in alternators, turbocompressors and pumps.

The system is based around a TQ402 or TQ412 non-contact sensor and an IQS900 signal
conditioner. Together, these form a calibrated proximity measurement system in which each
component is interchangeable. The system outputs a voltage or a current proportional to the
distance between the transducer tip and the target, such as a machine shaft.
The active part of the transducer is a coil of wire that is moulded inside the tip of the device, made
of Torlon® (polyamide-imide). The transducer body is made of stainless steel. The target material must, in all cases, be metallic.
