Description

The TQ402/TQ412, EA402 and IQS900 form aproximity measurement system, from Meggitt’svibro-meter® product line. This proximitymeasurement system allows contactlessmeasurement of the relative displacement ofmoving machine elements.TQ4xx-based proximity measurement systems areparticularly suitable for measuring the relativevibration and axial position of rotating machineshafts, such as those found in steam, gas andhydraulic turbines, as well as in alternators, turbocompressors and pumps.

The system is based around a TQ402 or TQ412non-contact sensor and an IQS900 signalconditioner. Together, these form a calibratedproximity measurement system in which eachcomponent is interchangeable. The systemoutputs a voltage or a current proportional to thedistance between the transducer tip and thetarget, such as a machine shaft.The active part of the transducer is a coil of wirethat is moulded inside the tip of the device, madeof Torlon® (polyamide-imide). The transducerbody is made of stainless steel. The target materialmust, in all cases, be metallic.

Information

Overview Manuals Application Notes Product Applications Installation Guidelines

Features:

  • Non-contact measurement system based oneddy-current principle

The Vibro-Meter TQ412 111-412-000-013 is an eddy current proximity probe manufactured by Vibro-Meter, a Meggitt Sensing Systems brand, originating from Switzerland. It belongs to the TQ400 series of proximity transducers designed for non-contact vibration, displacement, and speed measurement in rotating machinery condition monitoring.

The TQ412 features a stainless steel probe case with a non-metallic probe tip (polyphenylene sulfide or ceramic) that is electrically insulated from the case. The probe tip diameter is 8.0 mm, providing a balance between measurement area and installation space requirements. The probe mounts via threaded connection into standard probe holders or brackets.

The TQ412 S3960 111-412-000-013 Vibro-Meter Proximity Measurement System may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The probe operates continuously from –51°C to +177°C for both the probe tip and cable. Storage temperature spans the same range. Standard system lengths are 5.0 m and 9.0 m, achieved with appropriate probe and extension cable combinations.
The TQ412 111-412-000-013 carries no agency approvals as standard. For hazardous area installations, specify the appropriate agency approval option.
  • Gas Turbine Combustor Monitoring:Tracks dynamic pressure pulsations to prevent acoustic fatigue
  • Power Generation Facilities:Nuclear/hydro/thermal: safeguards high-vibration zones
  • Oil Refining and Petrochemical Processing:Tracks rapid pressure fluctuations in compressors/pumps
  • Automated Assembly Lines:Step-by-step diagnostics & cycle tracking for auto/electronics
  • Hazardous Industrial Zones:Class I Div2: oil/gas, chemical mixers & paint booths

Target Material: The standard target is VCL 140 steel (1.7225). If using a non-standard target, factory correction curves will be required.
Gap Distance: Adjust the transducer so its tip sits at the nominal gap recommended by the machine manufacturer (typically in the middle of the conditioner's linear range, such as 1.0 mm to 2.0 mm).
Locking: Once the gap is dialed in, tighten the mounting locknuts securely to prevent any vibration-induced shifting during machine operation. 

Technical notes

The TQ412 is specifically intended for reverse-mount installations where space limitations or machine design prevent the use of standard-mount probes. The active sensing element consists of a precision wire coil molded into a Torlon® tip and enclosed within a rugged stainless-steel housing. This construction provides excellent resistance to temperature variations, vibration, moisture, oil contamination, and harsh industrial environments.
