T3.0: Qualmark HALT Features

Qualmark Vibration Technology: 6DOF repetitive-shock table

• Simultaneous excitation at multiple frequencies for testing complex assemblies
• Patented pneumatic hammer/table design is lubrication-free and valveless
• Quiet operation without external cooling requirements
• The table is field-adjustable for resetting to original PSD levels, ensuring consistent performance. (Adjustment included in our preventative maintenance agreement.)

Cooling System

• Vacuum Jacketed (VJ) liquid nitrogen (LN2) valves and manifold.
• Proportional control and valve system for maximum LN2 efficiency and consistent temperature control, while reducing two-phase (gas/liquid) states that cause problems in traditional on/off solenoid-based control. (Proportional manifold optional on T1.5/2.0 models.)
• VJ eliminates condensation, dripping water, OSHA safety concerns, and energy loss compared to other insulation methods.
• Efficient, economical LN2 usage with either low-pressure Dewar tanks or higher pressure Permacyl and bulk tank systems.

Chamber Design

• Stainless steel interior, painted exterior, with two full opening doors (one door on T1.5/2.0 models)
• High-velocity airflow for improved product temperature change rates.
• Two-position table for flexibility to test taller samples, improved ergonomics, and less LN2/electricity usage for smaller test items. (except T1.5/2.0)
• Advanced chamber insulation combined with our low-noise hammers results in very quiet operation, even at maximum vibration levels.
• Adjustable feet for leveling unit (stand options for T2.5/3.0 models)

Control System

• Windows 10 system with Labview based operation and PLC-based controls
• Programming, operation, and datalogging for vibration/thermal profiles.
• One accelerometer for table control (three additional inputs available)
• Two thermocouples: one for product, one for air (four additional inputs available)
• Eight event relays for external controls
• Optional Q-Link or Qualview software tools for ATE integration and other remote connections.
• Optional integrated spectrum analyzers and data acquisition systems.
