Spider-100 Controller

The Spider-100 controller by Crystal Instruments is the control engine for environmental test THV chambers. (THV stands for Temperature, Humidity, and Vibration.) Based on the proven platform of Crystal Instruments Spider vibration controller, the Spider-100 precisely controls all aspects of a combined temperature/humidity and vibration test regime to meet testing requirements in various industries, e.g. automobile, aerospace, aviation, electronics, and military.

The Spider-100 is specifically designed to perform all types of tests where the DUT (device under test) is subjected to simultaneous vibration, temperature cycling, and variable humidity, including Highly Accelerated Stress Screening (HASS) and Highly Accelerated Life Testing (HALT). The Spider-100 controls temperature, humidity, and vibration harmoniously in a chamber and shaker system, which includes external heating/cooling and humidification/dehumidification systems. The communication between numerous devices is optimized by the Spider-100 in an integrated design to achieve high control accuracy. The Spider-100 provides eight voltage input channels and two shaker drive outputs for linear shaker control. When a pneumatic hammer table is used, the controller commands the RMS vibration level via its 4-20 mA current-loop output to the table’s pressure control valve. There is a total eight 4-20 mA analog out channels offered on the Spider-100. Additionally, the Spider-100 provides ten 4-20 mA analog input channels for humidity, various types of sensors, and eight temperature input channels for 3-wire RTD or J/K-type thermocouples. Thirty relay control channels control the heaters, compressors, valves, and air circulation system of the chamber. Thirty-two channels of programmable digital I/O serve as communication channels to other instruments and for user-defined applications.
