Uniphos Envirotronic’s Molecular Property Spectrometer (MPS) Sensor is a significant advancement in flammable gas detection. The MPS, which is based on precision thermal sensing and cutting-edge MEMS technology, offers unparalleled accuracy, stability, and multi-gas categorisation without requiring frequent maintenance or field calibration.
Certified for industrial-grade safety and reliability, this smart sensor offers robust protection in environments where gas detection cannot fail across oil & gas, chemical, power generation, wastewater, fire response, and more.
Why MPS Technology Changes the Game
True Multi-Gas Detection
MPS detects and classifies 14+ flammable gases automatically. The MPS sensor distinguishes between gas types in real time without manual configuration or correction factors.
Supported gases include:
Methane, Propane, Butane, Hydrogen, Ethane, Isobutane, Octane, Toluene, Pentane, Xylene, and more. MPS adapts to mixed gas environment without losing accuracy
No Field Calibration Needed
Conventional sensors drift over time and need periodic recalibration.But MPS has proprietary thermal signature analysis and integrated environmental sensing to eliminate drift and enable long-term stability offering a 15+ year lifetime with zero routine maintenance.
Immune to Poisoning. Resistant to False Alarms.
The MPS sensor is naturally poison-resistant and self-validating, in contrast to pellistors or NDIR sensors. Chemical inhibitors, dust, humidity, and pressure changes don’t affect how well it works. Even in harsh industrial settings, its integrated environmental adjustment guarantees reliable readings.
How It Works
- Gas enters the sensor chamber via a mesh-protected inlet.
- A Joule heater elevates the gas to specific thermal conditions.
- The system measures the thermal properties of the gas.
- Environmental parameters (temp, humidity, pressure) are factored in real-time.
- Gas type and concentration are identified and output via smart classification algorithms.
Resulting in stable, accurate %LEL readings with no need for gas-specific settings or external filters.
