The TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 is an eddy current displacement sensor. Together with an EA402 extension cable and an IQS900 signal conditioner, it forms a high-precision, non-contact proximity measurement system. This system is for large rotating machinery—such as steam turbines, gas turbines, hydro turbines, generators, turbo-compressors, and industrial pumps—to monitor the radial relative vibration and axial displacement (position) of the rotor shaft in real time.
Non-contact measurement system based on eddy-current principle
Ex certified versions for use in hazardous areas (potentially explosive atmospheres)
Voltage or current output with protection against short circuits
This specific configuration features an 8 mm tip diameter, with the active coil moulded inside a high-performance Torlon (polyamide-imide) tip, and a stainless steel body with a 42 mm unthreaded length. It includes a 1-meter integral coaxial PTFE cable terminated with a self-locking miniature coaxial connector. The paired signal conditioner generates the necessary electromagnetic field to measure the gap, outputting a linear voltage or current proportional to the distance to the metallic target.
Fully interchangeable and highly reliable, the system can be directly powered by associated machinery monitoring systems like VM600, VM600Mk2, or VibroSmart modules to ensure robust asset protection in harsh industrial environments.
The system is based around a TQ402 non-contact sensor 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 and an IQS900 signal conditioner. Together, these form a calibrated proximity measurement system in which each component is interchangeable. The system outputs a voltage or a current proportional to the distance between the transducer tip and the target, such as a machine shaft. This specific configuration features an 8 mm tip, a 42 mm unthreaded length, and a 1-meter integral cable.

During installation, the initial gap voltage must be strictly calibrated according to the measurement chain requirements, and the target must be made of standard ferromagnetic metal to ensure linearity. For cabling, maintain the minimum bending radius of the 1-meter integral cable to prevent damaging the flexible coaxial line, and keep the connector housed in a dry, oil-free junction box.
Additionally, since this configuration features a 42mm unthreaded length without armor, protect the probe tip from mechanical rub or pinching by thread walls during mounting, and always pair it with a compatible IQS900/IQS450 conditioner for reliable intrinsic safety and monitoring protection.
Vibro-Meter TQ402 (P/N: 111-402-000-013, config: S3960...H10) is a high-precision, non-contact eddy current proximity transducer compliant with API 670 standards. It features an 8mm tip, a 42mm unthreaded length, and a 1m oil-resistant, high-temperature PTFE cable with intrinsic safety support. Designed for harsh environments up to 180°C and 10 bar, it provides highly reliable radial vibration, axial displacement, and speed monitoring for critical rotating machinery like turbines and compressors.
