Description
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.The transducer body is available with metric orimperial thread. The TQ412 version is intended forreverse-mount applications. Both the TQ402 andTQ412 have an integral coaxial cable, terminatedwith a self-locking miniature coaxial connector.Various cable lengths (integral and extension)can be ordered.

Features:
- Non-contact measurement system based oneddy-current principle
- Ex certified versions for use in hazardous areas
- Conforms to API 670 recommendations
- Temperature-compensated design
- Voltage or current output with protectionagainst short circuits
The TQ400 series delivers a linear range of 2.0 mm (80 mils) with sensitivity of 4 mV/µm (100 mV/mil) or 8 mV/µm (200 mV/mil) depending on system configuration. System output is typically –2 VDC at the target gap. The sensor requires a companion signal conditioner (IQS450 or IQS451) and, for longer system lengths, a matching extension cable to complete the transducer system.
The TQ402 111-402-000-012 A1-B1-D000-E010-F0-G000-H05 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).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The TQ402 is used for radial vibration measurement, thrust position monitoring, differential expansion measurement, and speed/phase reference detection on critical rotating machinery including gas turbines, steam turbines, compressors, pumps, and motors. The target surface must be a minimum of 15 mm in diameter for proper field distribution with the 8.0 mm probe tip.
The TQ402 111-402-000-012 is an active product in the Meggitt catalog, available through authorized distributors. It is fully interchangeable with other TQ400 series components when matched with the appropriate signal conditioner. Related variants include the TQ401 (5.0 mm probe tip for tighter spaces), TQ403 (alternative 8.0 mm configuration), and TQ412 (alternative 8.0 mm configuration).

- 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
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Connections: The transducer’s integral coaxial cable is terminated with a self-locking miniature coaxial connector. It can connect directly to the signal conditioner or via an EA402 extension cable.
Protection: If connectors are exposed to harsh environments, use junction boxes, optional interconnection protectors, or flexible hoses to protect them from moisture and mechanical wear
Technical notes
The TQ402 proximity transducer is commonly used together with an IQS450 or IQS900 signal conditioner and an extension cable to form a fully calibrated measurement chain. This configuration delivers precise displacement measurements required for machinery protection systems and condition monitoring platforms.
FAQs
-
What is the TQ402 ?
+The Vibro-meter TQ402 is a highly reliable, API 670-compliant non-contact proximity transducer. It uses the eddy-current principle to measure the relative displacement and vibration of rotating machine shafts in heavy industrial environments like gas turbines, alternators, and turbo-compressors. -
How does it measure displacement?
+The TQ402 emits an electromagnetic field from its transducer tip. When a metallic target (such as a machine shaft) moves closer or further, it changes the field's impedance. The system scales this into a proportional voltage or current. -
What is the typical measurement range?
+It comes in 2 mm and 4 mm nominal measuring ranges. -
What temperature range can it operate in?
+The transducer is rated for temperatures from -40°C up to +180°C
