Designed for high‑reliability turbomachinery condition monitoring, the TQ402 111‑402‑000‑013 A2‑B1‑C072‑D000‑E015‑F0‑G100‑H10 is an eddy‑current proximity transducer complying with API 670 standard. It performs non‑contact measurement for rotating shaft status and transfers impedance‑change signals to matched extension cable and signal conditioner.
Product Overview
TQ402 111‑402‑000‑013 A2‑B1‑C072‑D000‑E015‑F0‑G100‑H10 is a standard‑mount proximity transducer. Adopting eddy‑current principle, it captures radial vibration, axial thrust displacement and key‑phase signals of rotating shafts. It features stainless‑steel housing, Torlon probe tip and integrated co‑axial cable. It cannot work independently and must pair with matching EA402 extension cable and IQS series signal conditioner.
Key Technical Parameters
Frequency response DC‑20 kHz (-3 dB): Covers low‑frequency displacement and high‑frequency vibration signals, captures fast dynamic changes of rotating shafts.
Working temperature -40℃ ~ +180℃: The probe tip adapts to high‑heat bearing‑housing environment, keeps stable performance under oil‑fog and harsh working conditions.
Complies with API 670 industry standard: Meets global turbomachinery protection specification, guarantees interchangeability and reliability for plant upgrade and spare‑part replacement.
Application Benefits
Non‑contact acquisition: No physical touch with rotating shaft, zero mechanical wear, supports long‑term continuous online monitoring.
Early fault identification: Supplies original sensing data for shaft vibration, thrust displacement and key‑phase measurement, helps spot rotor imbalance and bearing defects at early stage.
Good system compatibility: Matches EA402 extension cable and IQS signal conditioner; compatible with VM600 monitoring system, convenient for on‑site renovation and spare‑part swap.
Support predictive maintenance: Provides reliable raw measurement data for trend analysis, effectively reduces unplanned plant downtime.
Our field engineer reminds you that TQ402 must be used with matched extension cable and signal conditioner of specified system total length. Mismatched hardware combination will bring permanent measurement drift. Set proper gap between probe tip and shaft target during installation; avoid mechanical collision which may damage the transducer tip.

Power generation facilities
Metal processing & coal-chemical plants
Project Case Study
Vibro‑Meter TQ402 transducer was applied for a 22‑MW gas‑turbine unit at an Indonesia petrochemical plant in 2025. Combined with EA402 extension cable and IQS signal conditioner, it sends shaft vibration and thrust‑position signals to VM600 rack. Over 12‑month continuous running, it delivered steady raw signals and captured subtle vibration anomaly. The site took planned maintenance and avoided costly unexpected production loss.
Q1: Can TQ402 111‑402‑000‑013 A2‑B1‑C072‑D000‑E015‑F0‑G100‑H10 operate alone?
A1: No. It is only the proximity sensing transducer. It requires matched EA402 extension cable and IQS series signal conditioner. Complete measuring and alarm functions can only be realized after connecting to monitoring rack.
Q2: What factors will trigger abnormal measurement readings?
A2: Common causes include improper installation gap, mismatched system total cable length, cable damage, strong surrounding electromagnetic interference. Full‑loop inspection and gap calibration are needed after hardware replacement.
Q3: Can I pair this transducer with signal conditioners of other brands?
A3: Not recommended. For accurate measurement and stable performance, please adopt the complete matching measuring‑loop components. Mismatched third‑party hardware will cause sensitivity deviation.
