Built for high‑reliability turbomachinery condition monitoring complying with API 670 standard, TQ402 111‑402‑000‑013 A1‑B1‑C100‑D040‑E100‑F2‑G100‑H10 is an eddy‑current proximity transducer. It captures tiny physical changes on rotating shaft surfaces and transmits impedance‑variation signals through matched extension cable to signal conditioner. Many costly plant shutdowns are triggered by undetected subtle shaft vibration and thrust offset. Built to survive high‑temperature, oil‑fog bearing‑housing environments, this transducer delivers stable raw sensing data for mainstream machinery‑protection racks. It supports reliable asset monitoring for power, petrochemical and heavy‑industry facilities.
Product Overview
TQ402 111‑402‑000‑013 A1‑B1‑C100‑D040‑E100‑F2‑G100‑H10 is a standard‑mount proximity transducer. Based on eddy‑current measuring principle, it detects radial vibration, axial thrust displacement and key‑phase pulse signals of rotating shafts. It adopts stainless‑steel housing, high‑temperature Torlon probe tip, FEP‑sheathed co‑axial integral cable with movable BOA cable protection structure. It cannot operate independently. It must pair with matching supporting extension cable and compatible signal conditioner, and connect to corresponding monitoring rack to complete full‑loop measurement and machinery protection.
Key Technical Parameters
Frequency response DC‑20 kHz (-3 dB): Covers low‑frequency static displacement and high‑frequency dynamic vibration, captures fast transient shaft changes for turbomachine safety interlock.
Probe working temperature -40℃ ~ +180℃: Probe tip tolerates high‑heat bearing‑housing environment, maintains stable performance under oil‑fog and harsh industrial working conditions.
Complies with API 670 industry specification: Meets global turbomachinery protection requirements, guarantees hardware interchangeability for site retrofit and spare‑part replacement.
Application Benefits
Non‑contact signal acquisition: No physical contact with rotating shaft, zero mechanical wear, suitable for long‑term 24/7 online condition monitoring.
Early‑stage fault capture: Provides original sensing data for shaft vibration, thrust displacement and key‑phase measurement, helps identify rotor imbalance and bearing degradation ahead of serious failure.
Flexible system matching: Works with matched extension cable and supporting signal conditioner, compatible with mainstream monitoring platform; convenient spare‑part swap and on‑site system renovation.
Supports predictive maintenance: Supplies trustworthy raw measuring data for equipment trend analysis, effectively reduces risks of unplanned plant downtime.
Our field engineer reminds you that TQ402 111‑402‑000‑013 A1‑B1‑C100‑D040‑E100‑F2‑G100‑H10 must be deployed with matched extension cable and supporting signal conditioner of correct total‑system length. Mismatched hardware combination will result in permanent measurement drift. Adjust proper working gap between probe tip and shaft target during installation and avoid mechanical collision to protect transducer tip.

Project Case Study
TQ402 proximity transducer was installed on a 22‑MW centrifugal compressor unit at a Thailand petrochemical plant in 2025. Matched with supporting extension cable and signal conditioner, it feeds shaft vibration and thrust‑position signals to monitoring rack. During 12‑month continuous running, it delivered steady raw signals and captured subtle vibration anomaly. The site performed planned maintenance and avoided costly unexpected production loss.
Q1: Can TQ402 111‑402‑000‑013 A1‑B1‑C100‑D040‑E100‑F2‑G100‑H10 work by itself?
A1: No. It is only the proximity‑sensing transducer. It needs matched extension cable and supporting signal conditioner. Complete measurement and alarm functions can only be achieved after connecting to monitoring rack.
Q2: What factors lead to abnormal measurement readings for this transducer?
A2: Common causes include improper probe‑to‑target installation gap, mismatched total‑system cable length, cable damage, strong surrounding electromagnetic interference. Full‑loop inspection and gap calibration are required after hardware replacement.
Q3: Is it acceptable to pair this transducer with signal conditioners of other series?
A3: Not recommended. For accurate measurement and stable running performance, please adopt full set of matched measuring‑loop components. Mismatched hardware will cause sensitivity deviation.
