  • Precision Environmental Control Systems
    • Temperature Control: Capable of maintaining an extremely wide temperature range, from -80°C to +200°C, with an accuracy of ±0.5°C. It utilizes advanced cryogenic cooling and resistive heating technologies, integrated with a sophisticated feedback control system. Multiple temperature sensors are strategically placed throughout the chamber to ensure uniform temperature distribution and rapid response to any temperature deviations. The control panel allows for the programming of complex temperature profiles, including rapid temperature ramps, extended soak times at specific temperatures, and cyclic temperature sequences, replicating the temperature variations experienced during different phases of aerospace and defense operations, such as takeoff, flight at high altitudes, and re-entry.
    • Humidity Control: The humidity control system can achieve humidity levels from 5% to 95% RH, with an accuracy of ±3% RH. It employs a combination of steam injection humidifiers and desiccant dehumidifiers, synchronized with a laminar flow air circulation system. The chamber is equipped with high-precision humidity sensors that continuously monitor the internal humidity, and the control system makes real-time adjustments to maintain the desired humidity levels. This is crucial for testing the effects of moisture on electronic components, such as the potential for corrosion, short-circuiting, or degradation of electrical properties, especially in humid tropical or maritime environments.
    • Pressure Control: The chamber can simulate a wide range of pressures, from near-vacuum conditions (equivalent to high-altitude flight) to several times atmospheric pressure. The pressure control system is highly accurate, with an error margin of less than ±0.1 kPa. It uses vacuum pumps and pressure regulators to create and maintain the desired pressure levels. This is essential for testing the performance and integrity of electronics in aerospace applications, where rapid pressure changes and low-pressure environments can have significant impacts on component behavior, such as the outgassing of materials, the performance of seals, and the operation of pressure-sensitive devices.
    • Vibration and Shock Control: The vibration system is capable of generating a wide variety of vibration frequencies and amplitudes, simulating the vibrations experienced during engine operation, flight turbulence, and ground transportation. It can produce vibrations from 2 Hz to 2000 Hz, with amplitudes adjustable from 0.1 mm to 50 mm. The shock system can deliver precise shock pulses with adjustable magnitudes and durations, replicating the impact forces that may occur during landing, missile launch, or combat scenarios. The vibration and shock tables within the chamber are designed to provide a highly uniform and controlled excitation field, ensuring that all parts of the tested component experience the same mechanical stress. The control systems for vibration and shock allow for the programming of complex waveforms and sequences, enabling the accurate simulation of real-world events.
    • Electromagnetic Interference (EMI) and Compatibility (EMC) Testing: The chamber is equipped with an advanced EMI/EMC testing system, capable of generating and measuring a wide range of electromagnetic fields. It can simulate the electromagnetic environment that electronics will face in the presence of other onboard systems, radio frequency transmissions, and potential sources of interference. The system can measure the susceptibility of the tested electronics to EMI and evaluate their ability to emit electromagnetic radiation within acceptable limits. This is crucial for ensuring the proper operation of electronics in the highly electromagnetically congested aerospace and defense environments, where interference can lead to system failures, loss of communication, or incorrect sensor readings.
  • Advanced Instrumentation and Data Acquisition
    • The chamber is outfitted with a comprehensive suite of sensors and instrumentation. In addition to temperature, humidity, pressure, vibration, and EMI sensors, it includes sensors for measuring electrical parameters such as voltage, current, resistance, capacitance, and inductance of the tested electronics. These sensors are connected to a state-of-the-art data acquisition system that records and stores all relevant data. The data acquisition system offers a high sampling rate, typically ranging from 1000 to 10,000 samples per second, ensuring that even the most rapid changes in environmental conditions, mechanical stresses, or electrical performance are accurately captured. The collected data can be accessed and analyzed in real-time or retrieved later for in-depth studies. The system is also compatible with specialized aerospace and defense data analysis software, enabling the generation of detailed reports and graphical representations of the test results, which are essential for making informed engineering decisions.
