NevadaNano has published the results of five years of continuous operation of the MPS sensor. Despite frequent exposure to flammable gases, the accuracy of the sensor remained within specification. The sensor was not further calibrated and did not deteriorate or drift. The sensor was manufactured and calibrated in early 2017 and has been in continuous operation for up to 5 years.
Gary Collins, head of sales at NevadaNano said:"There is no other sensor that can achieve such stable and reliable accuracy without at least annual calibration," "These historical data highlight the important role MPS sensors play in creating a safe working environment and detecting potential hazards without the need for maintenance or replacement."
Assured Testing Services also performs independent performance tests on the sensors, as well as competing NDIR and Pellistor sensors, when exposed to methane, hydrogen and propane gases. Pellistor and NDIR sensors degrade after 10 days and require recalibration in less than 60 days. Only this company maintains its accuracy without maintenance.
Each sensor is available in various packaging formats. Based on accelerated life testing, the sensor lasts more than 10 years, is not poisoned, never needs calibration, and provides lower power than traditional sensors. The MPS gas sensor family includes MPS combustible gas sensors (0% to 100% LEL), MPS methane gas sensors (50 to 1Mppm range), MPS refrigerant sensors for a wide range of A1, A2L, A3 refrigerants and MPS configurable sensor, where any analog voltage can be used instead.
Featuring 27 patents on on-chip chemical analysis technology, the sensor is suitable for the most demanding security, HVAC-R and IoT applications. And technology is the first low-cost sensor technology that can accurately measure multiple gases without human intervention, and the first sensor technology that can measure multiple gases with only software changes. As a smart sensor with built-in environmental monitoring and algorithms, it can compensate for changes in temperature, pressure and humidity to provide accurate readings over the entire environmental range.
