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.

Information

Overview Manuals Application Notes Product Applications Physical & Mechanical Installation

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 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 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 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 widely applied in machinery protection systems for monitoring relative shaft vibration, axial position, shaft runout, eccentricity, and differential expansion. It is commonly installed on steam turbines, gas turbines, hydro turbines, generators, centrifugal compressors, pumps, and other high-value rotating assets.

The sensor supports multiple cable configurations and can be combined with an EA402 extension cable to accommodate installation requirements while maintaining calibration accuracy. Optional protective housings and junction boxes can be used to provide additional environmental and mechanical protection.

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

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.

Mounting: Mount the probe using an appropriate bracket. Ensure the probe is positioned perpendicular to the target surface.

Electrical Trimming: Due to the electrical characteristics of the coaxial cable, "trimming" of the nominal lengths of the integral and extension cables is required to optimize system performance and maintain interchangeability.

Thread Details: Ensure the thread size aligns with your mechanical setup.

Technical notes
