Request InfoMicronor Sensors Inc.Micronor Inc. has introduced the Model MR330 fiber optic absolute position sensor with an all-optical design immune to electromagnetic interference (EMI) such as lightning, radiation and magnetic fields. The fiber optic aspect of the sensor makes it suited for long-distance position sensing over hundreds of meters without being affected by ground loop problems. The sensor uses an optical technique embedded in a passive sensor and active controller connected by a duplex fiber optic link. The controller transmits a burst of light to the code disk in the sensor, which accurately modulates...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/24/2022Ethylene Oxide Monitoring SystemThe Ambient Air Monitoring System for Ethylene Oxide (EtO) has been announced by Picarro Inc., providing a continuous, automated solution for community monitoring stations and industrial fencelines....Photonics.com 4/27/2023Optical Time Domain ReflectometersThe D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...Photonics Spectra April 2023 IssueLaser Phase Lock SystemThe OE5000 Hi-Q Laser Phase Lock System from OEwaves Inc. allows the offset locking of two individual lasers separated in frequency by as much as 50 GHz.
