Designed and manufactured by Crystal Instruments, the Spider-101 controller is a key element of the Sentek Dynamics THV Series AGREE (Department of Defense Advisor Group on Reliability of Electronic Equipment) chambers.  These chambers offer combined temperature, humidity and vibration testing for environmental and reliability testing for a wide-variety of aerospace, automotive, medical, commercial and independent test lab applications.  Temperature, humidity and vibration are controlled with high accuracy and are synchronized to simulate the actual physical environment products see in the field.

The Spider-101 is the world’s first controller that supports combined temperature, humidity and vibration testing and reporting.  Crystal Instruments’ EDM (Engineering Data Management) software is used to control the combined temperature, humidity and vibration environment with Crystal Instruments’ EDC (Embedded Device Controller) software used when only temperature and humidity testing is required.

EDM is PC-based software used for combined temperature, humidity and vibration control.  Parameter and schedule setup between all three environments are fully integrated in one user interface.  Vibration tests such as Random, Sine, Shock, SoR, RoR, and others can be executed and reported together with various cycle settings of temperature and humidity.

When vibration testing is not required, the EDC software, is used for temperature and/or humidity testing without participating in vibration testing.  EDC is a touch screen application developed by Crystal Instruments that runs on any Windows 10 platform.

The Spider-101 provides ten input channels using either RTD or K-type thermocouple for temperature measurement and eight 4-20 mA input channels for humidity sensors. There are 32 configurable relay control outputs to control compressors and other mechanical systems, as well as digital I/O channels for alarm/status monitoring.

The Spider-101 controller can connect to the control PC or tablet via Ethernet ports or wirelessly for test setup and/or test monitoring. When combined temperature, humidity and vibration testing is required, the Spider-101 can combine with any dedicated Crystal Instruments’ vibration controller (Spider-81/81B, Spider-80Xi, etc.) through a network switch for accurate synchronized combined temperature, humidity and vibration testing.
