Overview
The SmartGas YK174-0321T is a high-frequency miniature displacement sensor engineered for dynamic mechanical measurement in transient and high-acceleration environments. Unlike conventional potentiometric or LVDT-based sensors, the YK174-0321T employs a precision-engineered resistive wire-wound core with low-mass sliding contact architecture, enabling reliable analog output under rapid axial displacement events. Its design prioritizes minimal inertial loading and mechanical hysteresis—critical parameters when measuring impact-induced deformation, drop-test kinematics, or shock pulse profiles in structural dynamics testing. The sensor operates on a passive DC-excited principle, requiring no internal signal conditioning, thereby ensuring intrinsic electromagnetic compatibility (EMC) and long-term stability across thermal gradients from −20 °C to +70 °C. It is not a gas detection device; its inclusion in environmental monitoring instrument catalogs reflects its frequent deployment in safety-critical infrastructure monitoring—e.g., real-time displacement tracking of blast doors, seismic isolation bearings, or pressure-vessel expansion joints—where correlated gas alarm systems may coexist but remain functionally independent.
Key Features
- High-frequency response capability up to 5 kHz (−3 dB point), validated per ISO 18431-1 for transient signal fidelity
- Compact cylindrical form factor (Ø12.7 mm × 65 mm) with integrated M6 threaded mounting interface
- Full-scale stroke of 102 mm (4 inches) achieved via high-tensile stainless steel cable actuation, rated for >100,000 cycles at nominal load
- Linear output deviation ≤ ±0.25% FS over operating temperature range, traceable to PTB (Physikalisch-Technische Bundesanstalt) calibration standards
- Hermetically sealed housing (IP67 rated) with gold-plated signal contacts to prevent oxidation in humid or saline test environments
- No internal electronics or power supply required—compatible with standard data acquisition systems supporting 0–10 V or 4–20 mA input ranges
Sample Compatibility & Compliance
The YK174-0321T is mechanically compatible with rigid fixtures, pendulum impact rigs, servo-hydraulic actuators, and drop towers where linear displacement must be resolved without introducing parasitic mass or resonance artifacts. It complies with DIN EN 61000-6-2 (immunity) and DIN EN 61000-6-4 (emission) for industrial electromagnetic environments. While not certified for hazardous area use (e.g., ATEX or IECEx), its passive construction and absence of spark-prone components permit deployment in Zone 2/22 classified facilities when installed per IEC 60079-14 guidelines. Calibration documentation adheres to ISO/IEC 17025 requirements and includes as-found/as-left data, uncertainty budgets, and traceability to national metrology institutes.
Software & Data Management
As an analog-output transducer, the YK174-0321T interfaces directly with industry-standard DAQ platforms—including National Instruments PXIe chassis, Dewesoft X, and HBM Catman AP—without proprietary drivers. Raw voltage or current signals are processed using configurable low-pass filtering (cutoff ≥10 kHz) to preserve rise-time integrity (<50 µs). When integrated into GLP/GMP-regulated test protocols, users implement audit-trail-enabled software (e.g., NI DIAdem with 21 CFR Part 11-compliant user management) to timestamp, annotate, and archive displacement waveforms. Firmware-independent operation eliminates firmware validation burdens during IQ/OQ/PQ qualification.
Applications
- Automotive crash testing: Measurement of bumper crush depth and crumple-zone displacement at 10–100 g acceleration levels
- Aerospace component validation: Monitoring landing gear strut extension during drop simulations
- Ballistics research: Quantifying plate deflection in behind-armor blunt trauma (BABT) studies
- Seismic simulation: Tracking relative displacement between base isolators and superstructure in shake-table experiments
- Material science: Characterizing strain-rate-dependent viscoelastic recovery in polymer composites under impact loading
FAQ
Is the YK174-0321T intrinsically safe for use in explosive atmospheres?
No—it lacks ATEX or IECEx certification. Its passive design minimizes ignition risk, but formal hazardous-area approval requires third-party evaluation and enclosure integration.
What is the recommended excitation voltage for optimal linearity?
5 V DC ±0.1% is specified for full-scale linearity compliance; higher voltages increase self-heating and thermal drift.
Can the sensor be used in vacuum environments?
Yes—its metal-sealed body and dry-film contact system support operation down to 10⁻³ mbar; outgassing rate is <1×10⁻⁹ Pa·m³/s per ASTM E595.
Does SmartGas provide NIST-traceable calibration certificates?
Yes—certificates include measurement uncertainty analysis per GUM (JCGM 100:2008) and are issued with each unit shipped.
Is cable replacement possible in-field?
The high-tensile steel cable is factory-terminated and non-user-replaceable; field repair requires return to authorized service center.
