Spider-81 Vibration Controller

Unlike traditional vibration test controllers that rely heavily on an external computer for real-time operation, the Spider-81 is the first vibration controller that directly integrates time-synchronized Ethernet connectivity with embedded DSP technology. This strategy greatly increases the control performance, system reliability and failure protection of the vibration test controller. It also allows a large number of channels to be configured without sacrificing system performance.

Latest Hardware Design

Spider-81 vibration test controllers have voltage, charge, TEDS, and IEPE inputs which are ideal for shock, vibration and acoustic measurement or general-purpose voltage measurement. The internal flash memory stores test configuration data for controlling up to 64 channels simultaneously in addition to storing real-time analysis data. Multiple output channels provide various signal output waveforms that are synchronized with the input sampling rate. A bright LCD screen displays testing status information. Ten monitoring connections on each unit are used to read signals of analog inputs and outputs. Built-in isolated digital I/O and RS-485 serial ports enable interfacing with other hardware.

Spider-81B

Basic Vibration Test Controller System

The Spider-81B vibration test controller is developed to meet the requirements of basic vibration testing applications. It has 4 inputs, 1 output, and 4 pairs of digital I/O.

Spider-81B Low cost, basic vibration control system

Software Features

The software includes Random, Sine, Shock, and RSTD testing suites.

  • Random Vibration Control Software
  • Swept Sine Vibration Control Software
  • Classical Shock Control
  • Resonance Search and Tracked Dwell (RSTD) Control

Black Box Mode: Operate Without a PC

The Spider-81B vibration test controller runs autonomously in Black Box mode without a PC connected. In this mode, a PC is used only to configure the control system before operation and to download data after the test is complete. During the test, the vibration test controller operates according to a preset schedule or from a choice of external devices using the digital I/O interface.

Intuitive User Interface

The vibration control software is further improved at the user interface level. More graphic guidance, wizards, and tools were added to make setup a snap. The interface has been rearranged to make it more logical and more useful. Event-Action rules, Abort-Sensitivity, and other new interface features are used to simplify operation. Searching through a large number of tests is easy with keywords.
