Other Brands Combined Temperature-Humidity-Vibration Test Chamber Model THV-500

Overview

The Other Brands Combined Temperature-Humidity-Vibration Test Chamber Model THV-500 is an integrated tri-environmental test system engineered for concurrent application of thermal, hygric, and mechanical stress stimuli. It combines a high-fidelity electrodynamic shaker with a climatic chamber capable of precise temperature and relative humidity control—enabling synchronized exposure of test specimens to real-world operational or storage environments. The system operates on the principle of controlled sinusoidal and transient vibration excitation (e.g., half-sine shock pulses), coupled with programmable thermal-hygrometric profiles. This architecture supports accelerated life testing, design validation, and reliability qualification across aerospace, automotive electronics, medical devices, and industrial IoT hardware where multi-stress interaction significantly influences failure modes.

Key Features

• Vertical-axis electrodynamic shaker with 500 × 500 mm moving table and 100 kg payload capacity—optimized for rigid mounting of DUTs up to mid-size enclosures or PCB assemblies.
• Wide dynamic range: 1–600 Hz frequency coverage with 0.01 Hz display resolution and PID-regulated closed-loop control ensuring traceable amplitude and acceleration fidelity.
• Dual-mode operation: programmable sweep (logarithmic or linear) and fixed-frequency testing, both supporting dwell, step, and level-change sequencing.
• Robust mechanical construction: cast steel side and base plates minimize structural resonance; high-rigidity voice coil actuator delivers flat spectral output across the operational bandwidth.
• Passive isolation system: dual-stage support using pneumatic air springs and hydraulic dampers eliminates need for floor anchoring while suppressing transmission of reaction forces to building infrastructure.
• Integrated environmental chamber with independent refrigeration, steam humidification, and forced-air circulation—capable of maintaining stable temperature (–40°C to +150°C) and humidity (10–98% RH) profiles during active vibration.
• Digital controller with anti-electromagnetic interference circuitry, real-time waveform monitoring, and user-configurable test duration (up to 31,536,000 seconds).

Sample Compatibility & Compliance

The THV-500 accommodates samples ranging from bare printed circuit boards and sensor modules to fully assembled electronic enclosures, automotive control units, and small medical instruments. Mounting adaptability is enhanced via standardized T-slots on the shaker table surface and optional fixture design support. The system is configured to meet foundational requirements of international standards including IEC 60068-2-6 (vibration), IEC 60068-2-64 (broadband random vibration), IEC 60068-2-3 (damp heat, steady state), and MIL-STD-810H Method 514.8 (vibration) and Method 507.6 (temperature/humidity). While not certified out-of-box, its architecture enables full audit readiness for GLP and GMP environments when paired with validated procedures, calibration records (traceable to NIST or equivalent national metrology institutes), and 21 CFR Part 11-compliant data logging software (available as optional upgrade).

Software & Data Management

Control and monitoring are executed via a Windows-based host application supporting intuitive test profile definition, real-time FFT spectrum visualization, and post-test time-history export in CSV and MATLAB-compatible formats. All test parameters—including setpoints, actual measured values, alarm states, and system health diagnostics—are timestamped and stored with SHA-256 integrity hashing. Optional firmware extensions provide automated report generation compliant with ISO/IEC 17025 documentation requirements, including operator ID, calibration certificate references, and uncertainty budget annotations. Data archives are encrypted at rest and support networked backup to NAS or cloud repositories with role-based access control.

Applications

• Design verification of avionics housings subjected to launch vibration spectra under sub-zero thermal soak conditions.
• Reliability screening of automotive ADAS ECUs exposed to combined humidity cycling and road-spectrum vibration.
• Qualification of implantable medical device packaging under accelerated aging protocols involving thermal-hygric-vibrational stress coupling.
• Failure mode analysis of solder joints in high-density PCBAs using resonant dwell tests at elevated humidity levels.
• Production line burn-in testing for industrial power supplies operating in harsh environmental duty cycles.

FAQ

Does the THV-500 support random vibration testing?
No—the standard configuration implements only deterministic waveforms (sinusoidal and half-sine). Random vibration capability requires optional broadband amplifier and controller firmware upgrade.
Can the chamber operate at full humidity range while vibrating at 20 g?
Yes—mechanical and thermal subsystems are decoupled; however, maximum achievable acceleration may be reduced above 85% RH due to condensation management protocols. Consult technical specification addendum for derating curves.
Is third-party calibration included with delivery?
Calibration certificates traceable to national standards are provided for shaker force, displacement, and chamber temperature/humidity sensors. Full ISO/IEC 17025 accreditation is available upon request at additional cost.
What maintenance intervals are recommended?
Shaker armature alignment and suspension inspection every 1,000 operating hours; refrigerant charge verification annually; humidity sensor recalibration semiannually.
Is remote monitoring supported over Ethernet or Modbus?
Yes—standard Ethernet interface supports TCP/IP communication for status polling and emergency stop initiation. Modbus RTU/TCP integration is available via optional gateway module.
