We turn optical fibers into intelligent systems
Solutions to monitor critical assets and processes through distributed fiber optic sensing technology
Talk to our engineersDISTRIBUTED ACOUSTIC AND TEMPERATURE SENSING
An integrated intelligent sensing platform built for critical infrastructure operators
DFOS (Distributed Fiber Optic Sensing) turns any standard optical fiber cable into a continuous sensing system with thousands of simultaneous measurement points, with no extra sensors along the infrastructure.
Thousands of acoustic, temperature and strain sensors with a single solution.
Over 70 kilometers monitored with a single device
One sensor every 3 meters of cable
AI and Machine Learning algorithms monitoring kilometers in real time
Alarms integrated with existing infrastructure
Nano-strain and microkelvin precision
Solutions:
From fiber to diagnosis, complete solutions for critical infrastructure
Immer Messen does not supply hardware alone. We deliver complete distributed monitoring systems, from the optical interrogator to the operational intelligence platform, adapted to each client's technical, regulatory and operational requirements.
DATS interrogator: DAS and DTS on the same fiber
A single device runs DAS and DTS simultaneously over the same installed fiber, reaching up to 60 km (DAS) and 30 km (DTS), with no new cables required.
AI algorithms and embedded software
Proprietary algorithms trained on Brazilian field data classify acoustic and thermal events, filter out noise and raise alerts with precise localisation — actionable information, not raw data.
Application-tailored solutions
Every project is tailored to the specific threat profile and regulatory context — gas and oil pipelines, transmission lines, submarine cables, wells and civil infrastructure.
Engineering and deployment services
Full coverage from design to commissioning: survey of existing fiber, system architecture, installation, calibration and integration with the client's systems.
Continuous monitoring
Subscription platform with secure remote access, configurable alarm management and automatic compliance reports — AI models continuously updated with accumulated field data.
Application areas
Transmission lines
Illegal tapping
Geophysics
Vessels
Environment
Site security
Subsea wells
WHO WE ARE
Born in the lab. Proven in the field.
Immer Messen originates in the research developed at the Federal University of Technology — Paraná (UTFPR), in Curitiba. It was inside the university labs that the first genuinely Brazilian DAS interrogator emerged — the result of years of applied research in photonics, optical metrology and signal processing.
From research to market
Recognition of Immer Messen's technological potential arrived before the commercial launch. Petrobras selected the company as a partner in an R&D project that validated the system's technical maturity and accelerated the development of oil and gas applications — establishing Immer Messen as the national technical reference in well and subsurface sensing.
Member of the NVIDIA Inception Program
Immer Messen is part of the NVIDIA Inception Program, a global initiative supporting deep-tech and artificial intelligence startups — recognition of the strategic role AI algorithms play in the platform and of its alignment with the frontier of machine learning applied to distributed sensing.
What defines us
We are the only Brazilian developer of DFOS technology with proprietary hardware, AI algorithms trained on national field data and the capacity to deliver a complete solution — from the optical interrogator to the continuous monitoring platform. Our local structure enables responsive support, competitive pricing and native alignment with Brazilian regulatory requirements.
