MPS™ Flammable Gas Sensor 5.0 Datasheet:

Overview

NevadaNano’s MPS™ Flammable Gas Sensor 5.0 represents the fifth-generation of this breakthrough technology, delivering industry-leading performance with a low cost of ownership. The smart sensor quickly detects, quantifies, and classifies myriad flammable gases and gas mixtures with unprecedented TrueLEL™accuracy. It comes already factory calibrated for its entire 15+ year life—no field calibrations are required—and has built-in environmental compensation and automatic self-testing for fail-safe operation. The sensor is robust, inherently immune to poisoning, and certified intrinsically safe. Sensor readings are output on a digital bus or a configurable analog output.

Gas Classification

The old way: Conventional sensing technologies (e.g. catalytic bead, NDIR) use a “k-factor” multiplier to convert raw sensor signals to gas concentrations in % LEL. These “k-factors” are based on known relative sensitivities of these sensors to different gases. A single “k-factor”, corresponding to a particular gas, must be selected manually during system setup; if the sensor is then exposed to a gas other than the one selected, significant errors in reported concentration can occur.

The MPS™ way: The MPS™ Flammable Gas Sensor applies a real-time conversion factor automatically, using the latest measured thermal properties of the ambient air/gas and the environmental conditions. The %LEL values reported for the bulk, which may contain a mixture of gases, achieves the same high levels of accuracy achieved with single gases.

How the MPS™ Flammable Gas Sensor 5.0 Works

The MPS™ Flammable Gas Sensor 5.0 is a smart sensor with built-in environmental compensation that detects and accurately quantifies over a dozen gases as well as gas mixtures. It is intrinsically safe, robust, extremely poison-resistant, and calibrated for all gases by performing only a single calibration with methane. Sensor readings are output on a standard digital bus or industry-standard analog
output.


The MPS™ transducer is a micro-machined membrane with an embedded Joule heater and resistance thermometer. The MEMS transducer is mounted on a PCB and packaged inside a filtered enclosure that is permeable to ambient air. Presence of a flammable gas causes changes in the thermodynamic properties of the air/gas mixture. These properties are measured by the transducer and processed by patented algorithms to report an accurate concentration and to classify the flammable gas.

Other sensing technologies (e.g. catalytic bead, NDIR) require a “k-factor” multiplier to convert raw sensor signals to gas concentrations in %LEL. These “k-factors” are based on known relative sensitivities of these sensors to different gases. A single “k-factor”, corresponding to a particular gas, must be selected manually during system setup; if the sensor is then exposed to a gas other than the one selected, significant errors in reported concentration occur.


In contrast, the MPS™ Flammable Gas Sensor 5.0 applies a real-time conversion factor automatically, using the latest measured thermal properties of the ambient air/gas and the environmental conditions.
