MiniMyotis 4ch
The MiniMyotis 4ch Unit is an optical signal conditioner developed by Phonoptics for use with its fiber optic sensors, including Evotis, Alpheus, tachometers and vibration sensors. It converts optical signals into standard electrical signals (±1.65 V AC or 0–4.5 V DC) for connection to data acquisition systems, oscilloscopes or computers. This easy-to-use, plug-and-play system includes a Noise-Eater function to significantly reduce optical noise.
