Digital Output Connections and Signal View for vibration testing software

Digital Input and Output (DIO) is the most popular interface used to communicate and interact with external instruments. Each digital input and output channel has only two states, high and low. The Spider can respond to the state of a digital input channel from an external instrument (e.g., an amplifier, an analyzer) or send a digital output to an external instrument to urgently shut down a device.

Turbine Blade Fatigue Testing Overview

Turbine engines are the power sources of aircrafts. The reliability of turbine engines is crucial when ensuring aircraft safety. Failure analysis of turbine engines reveals the catastrophic damage a turbine blade failure can cause to the engine, depending on the location of the blade. Turbine blade fatigue testing can help engineers investigate and improve the material and design of turbine blades.

Video Capture for Test Monitoring

Video Capture is a new EDM Extension that works with IP cameras for vibration test monitoring and data acquisition. This feature provides real-time video monitoring and video or photo recording of the test process or any object of interest along with data acquisition. The Video Capture feature is available in EDM VCS (vibration control system) and EDM DSA (dynamic signal analysis) software for the Spider platform. Dome or box type IP cameras using the ONVIF protocol are supported by the video capture feature.

Micro-vibration Measurements with CoCo-80X

The accurate measurement of micro-vibrations is the first step of successful vibration contamination control. According to generic vibration criteria for vibration sensitive equipment, the RMS velocity of vibration criterion is from 50 to 3.1 μm/s (2000 to 125 μin/s). To measure such small amplitudes, high sensitivity and low frequency sensors must be used. Crystal Instruments provides the Wilcoxon WR 731 and PCB 393B31 accelerometers with the CoCo-80X data analyzer for this application.

New Ultra-compact Spider-20H, Spider-20HE, & Spider-20i with 256 kHz Sampling Rate

Featuring the highest sampling rate provided in the industry at 256 kHz. Handheld battery powered system with wired & wireless network options and 20V input range. Sync between multiple devices. Choose the convenient portable model or industrial model for permanent mounting.

The Spider-20H, Spider-20HE, and Spider-20i received a hardware upgrade to support an impressive 256 kHz samping rate on all 4 input channels. It is the highest sampling rate offered in the market of compact analyzers. The high sampling rate is especially beneficial for measuring high orders and transient capture in blast tests, pyroshock events, drop shock tests, crash tests, etc.

In addition to the high samping rate, the input range is expanded to 20V to capture larger signals.
