Product Overview

Designed and produced by Crystal Instruments, the Spider-101 controller is a key element of the THV chamber system from Sentek Dynamics. THV stands for Temperature, Humidity and Vibration. Temperature, humidity and vibration are controlled with high accuracy and at synchronized levels to simulate the actual physical environment. The EDM software provides an integrated user interface to access and control all parameter setup, schedule, and test operation.

This is the world’s first controller (hardware) that is supported by two sets of software: EDM to control the combined THV environment and EDC (Embedded Device Controller) to control only the temperature and humidity.

EDM (a PC-based software developed by Crystal Instruments) is used when vibration control is required to be combined with temperature and humidity control. Parameter and schedule setup between all combined physical quantities are fully integrated in one user interface. Vibration tests such as Random, Sine, Shock, SoR, RoR, and other types can be executed together with various cycle settings of temperature and humidity.

The Spider-101 can also operate in an independent climatic chamber for temperature and/or humidity without participating in vibration testing. The EDC software developed by the Crystal Instruments is a touch screen application software that runs on any Windows 10 platform.

The Spider-101 provides ten input channels using either RTD or K-type thermocouple for temperature measurement, eight 4-20mA 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 a THV test type is required, the Spider-101 can combine with any vibration controller (Spider-81/81B, Spider-80Xi, etc.) from Crystal Instruments through a network switch for synchronized, accurate THV testing.

Software Designed for Combined Environmental Testing

EDC (Embedded Device Controller) and EDM THV are two software modules specifically designed for the Spider-101 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 Intel-based and ARM-based Windows 10 tablets, which can serve as wireless touchscreen terminals that users can mount to the testing chamber.

In addition, there is a wide selection of Windows tablets offered in the market that fulfill various requirements (such as the IP6X tablet). The Spider-101 controller runs on EDC software to conduct TH testing (without vibration) in independent climate chambers. Users can configure a test, operate a test, review test logs and review signals from the EDC interface.
