MPS sensors detect gases by measuring changes in the thermodynamic properties of the air/gas mixture, such as thermal conductivity and heat capacity. The sensor uses a micro-machined membrane with a Joule heater and a resistance thermometer to detect these changes. Advanced algorithms then calculate the gas concentration and classify the type of gas. MPS sensors automatically adjust for environmental factors in real time, do not require calibration throughout their lifespan, and are highly resistant to poisoning, making them more accurate and reliable over time.
Gases Detected
PureAire’s MPS LEL Flammable Gas Monitor accurately detects a wide range of gases with a single sensor, eliminating the need to purchase multiple gas sensors.
Gases detected by the MPS Flammable Gas Monitor include Hydrogen (H2), Propane (C3H8), Ethane (C2H6), Isopropanol (C3H8O), Methane (CH4), Ethylene(C2H4), Propylene (C3H6), Isobutylene (C4H8), Isobutane (HC((CH3)3), Butane (C4H10), Acetone (C3H6O), Methyl Ethyl Ketone(MEK) (C4H8O), Pentane (C5H12), Heptane (C7H16), Toluene (C7H8), Styrene (C8H8), Xylene (C8H10), and Octane (C8H18).
Long Life Molecular Property Spectrometry (MPS) Sensor
The MPS Flammable Gas Monitor features a durable MPS sensor with over 15 years of continuous operation. Uniquely designed by NevadaNano, this sensor can accurately detect, quantify, and classify flammable gas levels in various environments, setting it apart from conventional gas sensors.
Smart Electronics
The monitor integrates a specialized electronic circuit to continuously oversee the sensor’s operation. This advanced circuitry can promptly identify any sensor degradation or failure, alerting the user to any sensor faults or electrical issues that might disrupt surveillance via the standard mA signal output.
Factory Calibration
The MPS Flammable Gas Monitor is factory-calibrated for its entire lifespan, eliminating the need for any field calibration. This feature enhances usability and convenience, as the sensor maintains its accuracy and reliability without requiring periodic recalibration.
Environmental Compensation
The device uses a state-of-the-art MPS sensor that compensates for environmental factors like changes in temperature, humidity, and pressure. This ensures that the sensor’s performance remains consistent and accurate under varying environmental conditions.
PureAire’s MPS Flammable Gas Monitor is designed with an array of innovative features that facilitate ease of use and efficient operation. These unique characteristics have been thoughtfully incorporated to streamline the installation process, optimize daily functionality, and minimize maintenance needs. By fusing cutting-edge technology with user-centric design, the monitor delivers reliable performance while ensuring a simplified user experience.
