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
Ideal for OEM devices offering gas detection in hazardous locations requiring certification, the MPS™ 5.0 Flammable Gas Sensor meets rigorous performance standards.
Certified to EN 50271
Ensures functional safety and reliability for fixed, transportable, and portable detectors in industrial, commercial, and domestic settings.
Compliant With the Rigorous IEC 60079-29-1 Ed 2.1 Annex A Standard
Meeting rigorous gas detection performance standards for portable, transportable, and fixed detectors, ensuring they operate properly under various industrial conditions.
Rapid Start-up and Response Time
The MPS™ 5.0 Flammable Gas Sensor detects a broad spectrum of 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..
Catalytic Bead Sensor Replacement Ready
The 3-pin version of the MPS™ 5.0 Flammable Gas Sensor functions as a Catalytic Bead (Pellistor) Series 4 drop-in replacement and eliminates many of the fundamental limitations of catalytic bead technology.

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.
MPS™ 5.0 Certifications
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.
