TQ401 111-401-000-013

Product Overview

The TQ401 111-401-000-013 is a non-contact eddy current displacement sensor. This proximity sensor features high precision, high reliability, wide temperature range, explosion-proof design, and high interchangeability. It is specifically designed for precision measurement of shaft vibration and axial displacement in rotating machinery.

When combined with the IQS450 signal conditioner and EA401 extension cable, it forms a complete displacement measurement system. It is widely used for online monitoring and safety protection of equipment under extreme operating conditions in the power, energy, and petrochemical industries.

System Configuration

Component	Specification
Signal Conditioner	Must be used in conjunction with the IQS 450; supports voltage or current output modes
Extension Cables	The EA 401 series (5 m or 10 m) is available to extend the distance between the sensor and the conditioner
Connector Protectors	This model includes an integrated IP 172 protector (Part No. 013), suitable for damp or slightly contaminated environments
Junction Boxes/Enclosures	An external junction box or explosion-proof enclosure is available for installation in hazardous areas

Key Features

Non-contact measurement: Based on the eddy current principle, suitable for dynamic measurement of high-speed rotating machinery
Explosion-proof certification: Supports Ex i (intrinsically safe) and Ex nA (non-sparking) explosion-proof ratings, suitable for hazardous environments
Wide temperature range: The sensor can withstand temperatures from -40°C to +180°C, and the signal conditioner operates stably in environments ranging from -35°C to +85°C
Wide frequency response: DC to 20 kHz (-3 dB), suitable for high-frequency vibration signal acquisition
Flexible Output: Supports voltage (-1.6 V to -17.6 V) or current (15.5 mA to 20.5 mA) output with short-circuit protection
High System Interchangeability: All components are interchangeable, facilitating maintenance and calibration
Multiple Length Configurations: Supports total system lengths of 5 m and 10 m to accommodate different installation distances

Case Study

A compressor shaft at a certain petrochemical plant exhibited abnormal vibration, necessitating real-time monitoring of the turbine compressor shaft to prevent unexpected shutdowns.

The petrochemical plant implemented a monitoring solution consisting of a TQ 401 111-401-000-013 sensor paired with an IQS 450 signal conditioner. The system was installed on the compressor bearing housing, and its 4-20 mA output signal was integrated into the DCS system.

Ultimately, the system successfully captured high-frequency vibration signals, providing early warning of bearing wear and preventing a major shutdown incident.

Frequently Asked Questions

In which types of equipment is TQ401 111-401-000-013 primarily used?

Rotating machinery such as steam turbines, gas turbines, generators, compressors, blowers, pumps, and hydro turbines.

If the probe is broken, can I just replace it with one of the same model?

Yes. All components of the TQ401+IQS450 system are interchangeable, and no recalibration is required after replacement.

What is the warranty period?

Standard industrial warranty: 12 months; with proper installation and no overloading, the product has a service life of 5-10 years.
