VIBRO METER TQ402 111-402-000-013-A3-B6-C050-D000-E100-F1-G100-H10 – Electromagnetic Induction Displacement Proximity Probe

Product Description

VIBRO METER TQ402, full order code 111-402-000-013-A3-B6-C050-D000-E100-F1-G100-H10, is an eddy current proximity transducer of Vibro-Meter (Meggitt) TQ series, compliant with API670 standard. It adopts non-contact eddy current measuring principle. The probe tip diameter is 8.2mm with standard front mounting structure and integrated coaxial cable. It must work together with IQS450 signal conditioner and optional EA402 extension cable to form a complete shaft vibration and axial displacement monitoring system. With hazardous area approval and IP68 rating, it withstands wide temperature range and harsh environment for rotating machinery. It continuously measures shaft relative vibration and axial position, acting as core sensor for turbine and compressor machinery protection system. This model is widely used as spare part for rotating machinery condition monitoring.

Product Application

It is applied on large rotating equipment such as steam turbines, gas turbines, centrifugal compressors, pumps and fans. It performs non-contact measurement of shaft relative vibration, axial displacement, shaft eccentricity and rotor expansion. Signals are sent to VM600, VibroSmart and other vibration monitoring systems for online condition monitoring, alarm and interlock protection. Widely deployed in power plants, oil & gas, refining and chemical industries, meeting API670 machinery protection specification. It is essential sensor for large rotating machinery condition monitoring and protection.
