NevadaNano’s MPS Mini Flammable Gas Sensor is the next generation of gas detection and quantification for worker safety and leak detection in drilling, transportation, and production of oil & gas and chemical products. The smart sensor quickly detects and accurately quantifies over a dozen gases and gas mixtures using a standard factory calibration. It has built-in environmental compensation and automatic self-testing for fail-safe operation. It is robust and extremely poison resistant. Sensor readings are output on a digital bus or configurable analog output – no added electronics are required. With a 15-year lifetime and no calibration required, the MPS Mini Flammable Gas Sensor delivers industry-leading performance and a low cost of ownership.

Operating Principle

The MPS Mini Flammable Gas Sensor’s 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 rugged enclosure open to ambient air. Presence of a flammable gas causes changes in the thermodynamic properties of the air/ gas mixture that are measured by the transducer. Sensor data are processed by patent-pending algorithms to report an accurate concentration and classify the flammable gas.

Accuracy guaranteed for methane and hydrogen across full environmental range. Other gases typically meet the published tolerances across the full environmental range, but are guaranteed only near standard conditions. The MPS Mini Flammable Gas Sensor is capable of detecting most common flammable gases/vapors
