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
- Conforms to API 670 recommendations
- Temperature-compensated design
- 1, 5 and 10 m systems
- Voltage or current output with protectionagainst short circuits
The sensor operates on the eddy current principle, generating a high-frequency electromagnetic field that induces eddy currents in a conductive target surface. The resulting impedance change is measured by the companion IQS450 or IQS451 signal conditioner, producing a DC voltage output proportional to the gap between the probe tip and the target surface. The system provides both static (position) and dynamic (vibration) measurement capability.
The TQ412 AF70982 111-412-000-012 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 TQ412 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.

- 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.
Hand-tightening: Connect the integral coaxial cable to a matching EA402 extension cable or directly to the IQS-series signal conditioner. Always hand-tighten the self-locking miniature coaxial connectors until they are fully locked. Do not use pliers or tools.
Environmental protection: Use optional junction boxes or interconnection protectors to shield the connections from moisture, oil, and dust.
Trimming requirements: Due to the electrical characteristics of coaxial cables, an "electrical trimming" of extension cable lengths is sometimes required to optimize system interchangeability and performance
Technical notes
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.
FAQs
-
What is the TQ412 ?
+The Vibro-meter TQ412 is a non-contact, reverse-mount eddy-current proximity sensor used to measure relative shaft vibration and axial displacement. -
What is the primary function of the TQ412?
+It provides contactless measurement of relative shaft displacement. It tracks shaft vibration, gaps, and axial positioning in critical rotating machinery -
What types of machinery use this sensor?
+It is engineered for steam, gas, and hydraulic turbines. It also monitors alternators, turbo-compressors, and heavy-duty industrial pumps -
What makes the TQ412 different from the TQ402?
+The TQ412 features a reverse-mount design. This setup makes it ideal for compact, cluttered, or restricted mechanical installations
