MPS Flammable Gas Monitor – Redefining Gas Detection Technology

Introducing PureAire’s MPS Flammable Gas Monitor

PureAire Monitoring Systems is pleased to introduce its Molecular Property Spectrometer “MPS” Flammable Gas Monitor. This state-of-the-art gas detection solution, built with a 15+ year sensor, sets a new standard in precision and reliability. Engineered to provide unmatched performance, our MPS Flammable Gas Monitor delivers accurate readings for a wide range of combustible gases, making it ideal for complex industrial applications where safety and efficiency are paramount.

PureAire’s MPS Flammable Gas Monitor detects, classifies, and compensates for more than 14 combustible gases, including hydrogen and hydrogen mixtures, natural gas, and light, medium, and heavy gas mixtures, making it suitable for monitoring numerous combustible gases, eliminating the need for multiple sensor installations.

Advanced  MEMS Transducer Technology

Unlike traditional catalytic bead or NDIR sensors, the sensor in our MPS Gas Monitor utilizes a micro-machined membrane with an embedded Joule heater and resistance thermometer to provide real-time classification and conversion factors, delivering accurate Lower Explosive Limit  “LEL%” readings with minimal environmental interference.

Ease of Integration

With a sensor life exceeding 15 years of continuous operation, the MPS Gas Monitor stands out for its exceptional durability and minimal maintenance requirements. The MPS Monitor does not require calibration, and the sensor is highly resistant to poisoning, ensuring consistent performance over time. The Monitor’s performance and accuracy will remain consistent regardless of temperature, humidity, or pressure changes, minimizing the risk of false alarms. Its user-friendly design simplifies the installation process while enhancing daily functionality, ensuring the MPS Monitor seamlessly integrates into customers’ workflows, providing long-term reliability, no scheduled maintenance, and no costly downtime. The Monitor is equipped with an RS-485 interface, which allows for communication with centralized systems or with PureAire’s line of Multi-Channel Controllers, enabling scalable monitoring across facilities.

Built for Harsh Environments

“The MPS sensor technology offers a non-depleting solution for flammable gas detection in industrial environments.” The MPS Monitor is housed in a corrosion and water-resistant NEMA 4 Explosion-Proof Enclosure certified for Class I & II locations, making it well-suited for the harshest environments, including oil and gas, chemical processing, semiconductor manufacturing, pharmaceutical production, agriculture, and any other locations where safety is a top priority.

PureAire’s MPS Flammable Gas Monitor meets or exceeds the requirements of industry standards, including OSHA guidelines for workplace safety, IECEx and ATEX certifications for explosive environments, and adherence to NIST traceability for accurate measurement and classification.

The Cold Truth: Why Traditional Ammonia Sensors Fail – and How PureAire Leads the Way

 

Ammonia is an essential refrigerant used in food processing, cold storage, and industrial manufacturing due to its efficiency and cost-effectiveness. However, detecting ammonia leaks in cold environments presents significant challenges. Many traditional ammonia sensors fail, provide inaccurate readings, or require frequent maintenance due to freezing conditions.

PureAire engineered its Universal Gas Detectors to overcome these challenges. Unlike conventional ammonia sensors, it features a proprietary renewable electrochemical (EC) sensor with an advanced electrolyte formulation designed to prevent freezing. This innovation ensures reliable performance in ultra-cold environments without sensor degradation.

Why Do Most Ammonia Sensors Fail in Cold Environments?

Most ammonia sensors fall into three primary categories, each with inherent limitations when used in cold storage and industrial refrigeration settings:

Chemisorption (MOS) Sensors – Unreliable in Cold & Low-Humidity Environments

• Non-specific to ammonia, leading to inaccurate readings and false alarms.
• Prone to failure in ultra-cold conditions due to dried-out sensing elements.
• Fluctuations in humidity cause inconsistent readings.
• Requires frequent calibration, leading to increased maintenance costs.

Standard Electrochemical (EC) Sensors – Susceptible to Freezing & Short Lifespan

• Temperature Sensitivity – Standard EC sensors freeze in low temperatures, causing sensor failure.
• Short Operational Life – Typically lasts only 1-2 years and degrades quickly in ammonia-rich environments.
• Electrolyte Freezing Issues – The internal electrolyte solution in traditional EC sensors cannot withstand freezing temperatures, leading to operational failure.

Infrared (IR) Sensors – Unstable in Extreme Temperature Fluctuations

• Vulnerable to frost buildup, which interferes with sensor readings.
• Requires additional environmental protection, increasing overall system costs.
• Frequent recalibration is necessary, reducing operational efficiency.

PureAire – Renewable Freeze-Resistant Electrolyte Electrochemical Sensor

Unlike conventional EC sensors, PureAire’s ammonia sensor is uniquely engineered with an electrolyte solution that prevents freezing, ensuring consistent performance in extreme cold, making it ideal for applications such as meat processing plants, refrigerated warehouses, and pharmaceutical cold storage.

Key Advantages of PureAire’s Advanced Ammonia Sensor Technology

✔ Cold-Resistant Electrochemical Sensor – Designed to prevent freezing, ensuring accurate ammonia detection in ultra-cold environments.

✔ Extended Sensor Lifespan – Up to 8 Years – Significantly outlasts standard EC sensors, which typically last 1-2 years and require frequent replacement, making them more costly. PureAire’s long-life EC sensors reduce replacement frequency and costs.

✔ Minimal Maintenance Requirements – Unlike MOS and standard EC sensors that require frequent recalibration, PureAire’s sensor is nearly maintenance-free.

✔ Continuous Monitoring with Self-Diagnostics – Automated system checks eliminate the need for manual monitoring, ensuring uninterrupted operation.

✔ Seamless Integration with Building Automation Systems – Compatible with SCADA, PLC, BACnet, and Modbus systems via 4-20mA output and dual-level alarms, making it an ideal solution for industrial refrigeration.

Industries That Benefit from PureAire’s Ammonia Sensors

PureAire’s advanced ammonia detection technology is a game-changer for industries that require reliable monitoring in cold environments, including:

• Food Processing and Cold Storage – Meat, poultry, dairy, and seafood processing facilities rely on ammonia refrigeration.
• Beverage and Brewery Facilities – Large-scale beverage production plants utilizing ammonia-based cooling systems.
• Pharmaceutical Manufacturing – Facilities requiring ultra-cold storage for sensitive medications and vaccines.
• Ice Production and Frozen Goods Warehousing – Reliable, needing robust ammonia leak detection for safety and compliance.
