Combined Environmental Testing The industry trend demands environmental testing conducted in fully integrated environments. Various physical parameters, including vibration (acceleration, velocity and displacement), temperature, humidity, pressure, torque, and electrical signals such as those from CAN bus should be monitored and controlled by one system. Crystal Instruments made dedicated efforts to achieve this goal. Test status page of EDC on a wireless, touchscreen terminal Using the Ethernet network and PTP time synchronization technology, all Spider hardware devices connected to the...

EDC running on a touch screen terminal Ethernet Connec�on Chamber Spider-101 Controller Temperature Measurement & Control Humidity Measurement & Control Software Designed for Combined Environmental Testing EDC (Embedded Device Controller) and EDM THV are two software modules specifically designed for the Spider-101i to perform Temperature/Humidity (TH) or Temperature, Humidity, and Vibration (THV) control tests. EDC is a lightweight Windows application with an interface designed for touchscreen use. It runs smoothly on both Windows 10 computers and tablets, which can serve as mobile or...

Temperature Measurement in Vibration Testing Multi-module Setup The Spider-80Ti is a front-end from the Spider-80Xi hardware platform that adds 16 temperature measurement channels to a Spider-80Xi system, which can be a vibration controller system or a part of a vibration controller system. RTD Non-Linearity Correction To provide high accuracy during measurements the Spider-80Ti directly implements the IEC 751 RTD equations, the user can choose to use the coefficient values as defined by the standard or specify custom coefficients. Having these customizable coefficients also allows the user...

Spider systems use superior Ethernet and time synchronization technology developed by Crystal Instruments which allows modular expansion to support up to 512 input channels. When a system is running with multiple front-ends totaling to hundreds of input channels, all data is simultaneously acquired and is accurately phase matched. The phase match accuracy can be less than 1 degree within the normal testing frequency range. By providing such high phase match, the frequency response function of cross channel measurement can be used for analyzing the characteristics of the UUT (unit under...
