![Light guide [liquid / bundle fiber]](https://image.mono.ipros.com/public/premium/image_category/d58/65067/IPROS53721546032777621267.jpeg?w=140&h=140){kind=small}
Acoustic sensors that can be used in harsh environments such as high temperature, high pressure, high humidity, high magnetic fields, and radiation environments.
The Myotis 1400ht from Phonoptics is a fiber optic acoustic sensor designed to withstand harsh environments such as high temperatures, high pressures, high humidity, electromagnetic interference (EMI/RFI), strong magnetic fields, and radiation. It is capable of collecting sound in locations where other microphones cannot operate. ■ Utilizes patented sensor technology and fiber optics With MM50 fiber, microphones can be used up to 10 km from the converter, and with SM fiber, even further distances are possible. ■ The sensor is compact and easy to install Output options include BNC output, 3.5mm audio jack, and USB. ■ Myotis 1400ht product configuration - Acoustic sensor - Converter - Power cable
