MPS™ 5.0 Flammable Gas Sensor
Certified for EN 50271 applications and 60079-29-1 Ed. 2.1 Annex A compliant, this sensor is ideal for connected worker safety devices.
Meets Rigorous Gas Detection Performance Standards
For gas detection in hazardous locations, both functional safety (EN 50271) and sensor performance (IEC 60079-29-1) are critical. If a sensor’s software is reliable but its detection performance is poor, the system isn’t truly safe. The MPS™ 5.0 Flammable Gas Sensor is one of the few gas sensors that checks both boxes:
- Certified to EN 50271 – Ensuring software safety and reliability
- Compliant with IEC 60079-29-1 Ed. 2.1 Annex A – Meeting rigorous gas detection performance standards.
Rapid Start-up and Response Time
The MPS 5.0 Flammable Gas Sensor detects over a dozen of the most common combustible gases, including Hydrogen and begins checking for gas as early as 32 seconds seconds after power on with a fast response time (T90) <20 seconds.
The Gold Standard in Gas Detection
No-maintenance features = low total cost of ownership
- Automatic multi-gas accuracy in real-time
- 15-year sensor life
- No field calibration required for the life of the sensor
- Low power — 29 mW average
- Certified Intrinsically Safe (S4 format)
- Immune to poisoning and saturation
- Built-in environmental compensation
- Built-in self-test for fail-safe operation
What Gases the MPS 5.0 Flammable Gas Sensor Detects
The MPS™ 5.0 Flammable Gas Sensor detects a broad spectrum of combustible gases and mixtures with a single factory calibration. We provide verified TrueLEL™ performance for a subset of gases that have been fully validated for high-accuracy %LEL measurement, while gas classification provides additional insight into the type of gas present—especially in multi-gas environments.

Highly Robust and Built-in Self Test Features
The MPS™ sensor has a very wide operating range of -40°C to 75°C with up to 100% relative humidity It has built-in environmental compensation and automatic self-testing that continuously evaluates the system to ensure it is operating to specification. The sensor is certified for all flammable gas environments with ATEX, UL and IECEx certifications.
The MPS™ 5.0 Flammable Gas Sensor comes in two different formats: The S4 (3-pin and 5-pin options) and the Mini. The S4 is intrinsically safe for certified applications, and the cost-effective Mini targets a variety of applications. Sensor readings are output on either a UART digital bus that provides gas classification or analog output for pellistor replacement with improved performance.
