The Adash A4300 VA3 Pro Ex Three Channel Vibration Analyzer is the latest ATEX rated addition to Adash's extensive selection of portable vibration diagnostic devices. The design consists of 2 signal inputs and 1 tacho/trigger input. The second input can support connection to a triaxial sensor, so that all 3 channels can be measured simultaneously. This design also boasts a non-contact IR temperature sensor for immediate bearing temperature readings.

The A4300 VA3 Pro Ex system comes standard with Adash's Meter module, which provides 6 screens of vibration measurements including overall vibration values, FFT, time signals, frequency bands, displacement, and temperature. The A4300 VA3 Pro Ex also comes equipped with two additional complementary modules (FASIT and STROBO), which further expand the various application uses of this system. The FASIT module is a fault source detection tool that automatically identifies machine faults (unbalance, looseness, misalignment, bearing). The STROBO module pairs with the LED stroboscope (and alternative flashlight), to provide machine speed detection of any moving parts.

Key specifications include fully simultaneous sampling for 3 channels, 24-bit AD conversion with 64-bit internal signal processing, frequency ranges from 0.5 Hz to 25 kHz, and FFT resolution up to 25,600 lines. The unit features 8 GB memory, removable Li-Ion battery pack with 6+ hours operation, and USB 2.0 communication. The heavy duty aluminum casing provides durability in field use, and the ATEX rating II 3G Ex ic op is IIC T3 Gc allows use in hazardous areas.
