The gap
Why Conventional Monitoring Fails
Most plants still rely on snapshots instead of continuous physics—leaving high-heat zones and true 24/7 coverage on the table.
Electrical sensors fail in harsh zones
Heat, EMI and corrosion reduce reliability.
High heat kills field electronics
Steam, furnaces, and process temperature push active sensors out of range where you need the signal most.
Not truly 24/7, passive, always-on
Rounds and spot checks are not the same as continuous, high-reliability, passive coverage.
Critical assets fail without warning
No early detection means expensive downtime.
Large facilities are difficult to monitor
Long cable runs and distributed assets increase complexity.
Architecture
Photonics-Based Continuous Intelligence
Passive fiber sensors installed near assets send critical information to optical interrogators, with edge computing close to the measurement chain to run pattern identification, thresholding and correlation against baselines. That stack issues structured alarms to operators — e-mail, SCADA/OPC, or your plant's event bus — while keeping high-sensitivity, localized observations and scalable multi-channel coverage without energized electronics at the sensor.

Technical performance
Acoustic bandwidth & thermal envelope
MKFotônica builds passive, fiber-coupled opto-acoustic systems for industrial condition monitoring: from low-frequency, structure-borne content up through ultrasonic emissions, with remote interrogation and normal plant interfaces (e.g. SCADA).
Why ultrasound & signatures
A large share of incipient problems—leaks, valves, early wear—shows up in the ultrasonic / high-kHz part of the signature, or as small changes a wideband path can tease from plant noise. Many acoustic devices with a narrow, audible-limited view of the spectrum do not “see” that band, so the line looks clean until the fault is big. Deliberate ultrasonic measurement and edge signature identification are what make those events measurable—and alarmable—early.
Bandwidth & sensitivity
Sub-Hz to ultrasonic, tuned to the application
Sensing is based on fiber interferometric heads in several designs. A typical chain covers a few hertz through about ~100 kHz with very high sensitivity in the bands you select (filters and conditioning target the failure signature, not indiscriminate noise). In configurations aimed at high-frequency emissions, capability can reach deep into the ultrasonic range (order of ~500 kHz where the product line supports it), alongside band-limited heads for specific problems.
Temperature
High-heat process environments
Where electronics cannot sit at the measurement point, the sensor path supports ~300 °C continuous operation and ~400 °C peaks, for ultrasonic-style monitoring in superheated steam, furnaces and similar—while the interrogator and software stay on remote fiber.
The portfolio offers several interferometric families with different band and coupling options so the right head can match your asset and failure mode.
Exact bandwidth, filters and temperature limits depend on sensor variant, installation and factory calibration. Engineering can map these to your duty cycle, standards and target defect classes.

Portfolio
Products & Platforms
Modular building blocks for deployment-grade reliability — from the OAS-1 class interrogation platform to localized interferometric heads and geotechnical-oriented, geophone-class configurations. Edge software layers add pattern-based detection and alarm routing (e-mail, SCADA/OPC) to match your plant workflow.
Optical Interrogator
Field systemHigh-performance DSP & photonics core for dense fiber channels — rack systems with multi-port front panels for field deployment.
Localized High-Sensitivity Sensors
Point / GeotechPoint-localized, high-sensitivity interferometric heads—not a distributed sensing cable. Primarily aimed at leak, steam and utility-related acoustic signatures with tight mechanical coupling to the asset. The same portfolio extends to geophone-class optical responses for mining, geotechnical and structural monitoring (ground motion, slope/tailings contexts, and structural health scenarios). Where required by the transduction design, a sensor can be engineered to track instantaneous temperature variation with millidegree-class (m°C) resolution on the measured variable; absolute temperature is not a present capability and remains part of the development portfolio.
Acoustic Fiber Sensor
ProbeInterferometric opto-acoustic heads for targeted bands — including resonant designs (e.g. 55 kHz class) for high-sensitivity capture when the physics of interest align with a defined resonance strategy.
