Industrial Mems Sensors. A Brief History of MEMSA Broad Sensor OfferingSensor Accuracy Is Key For Many Industrial ApplicationsWhat Makes A Sensor accurate?Sensors have been around in industrial environments for over a hundred years as a critical element in process and environmental control One of thefirst accelerometerswas developed in 1889 and was purely mechanical Often these sensors were designed for a target application with specific operating conditions making and they are relatively costly and timeconsuming to manufacture Smaller and more power efficient MEMS (MicroElectronicMechanicalSystems) sensors were originally designed to replace or upgrade some of these industrial sensors However the focus on industrial markets was sidetracked as MEMS quickly took off in consumer applications such as gaming and smartphones thanks to their size performance and low power consumption Especially important was the possibility to manufacture MEMS using semiconductor technologies in very high quantities As a result manufacturers have shipped tens of billions of sensors into highvolume consumer applications in the last decade – w ST offers a range of compact highaccuracy high stability lowpower industrial sensors with a 10year longevity guarantee These include accelerometers gyroscopes 6axis Inertial Measurement Units (IMU) and magnetometers ST also offers a range of temperature and pressure sensors suitable for environmental monitoring These sensors can be combined with microcontrollers and connectivity elements to create smart solutions for industrial equipment monitoring throughout the equipment’s lifecycle – from transport through installation to longterm operational maintenance During shipment accelerometers can be used to monitor shock and vibration while temperature and pressure sensors can monitor the environmental conditions encountered during transport During installation a high resolution a highstability inclinometer can measure inclination and other accelerometers can monitor for shock and vibration Environmental sensors can monitor conditions during installation These meas In many industrial settings accuracy is a key factor Whether it is to measure temperature and pressure control in a manufacturing process inclination measurement for equipment installation or vibration measurement for condition monitoring in industrial applications manufacturers cannot settle for secondrate sensors With long experience in sensors ST knows that to build a great accurate sensor that fits the application we need three key items First we need to be able to measure the phenomenon you are sensing – movement vibration sound pressure etc Here the tiny moving mechanical part and electronic elements of the MEMS device are key The electronic part converts changes in the device characteristics caused by movement of the mechanical part into an electrical signal and then into digital information about the physical change Next we need the sensor to have all the right features to address the application in question – for example the right size the right power c Accuracy is a measure of how closely the output from a sensor matches the ‘true’ or actual value of what the sensor is measuring Accuracy in a sensor depends on 1 Its ability to deal with noise in the measurement environment 2 Its stabilityover time and ambient temperature and 3 its tolerance the permissible limit or limits of variation While a sensor’s noise immunity is a function of the sensor design (mechanical and electronic) its stability and tolerance are mainly a function of testing and calibration along with the associated algorithms that are embedded in the sensor Manufacturers have been producing highly accurate industrial sensors in relatively low quantities up to now because of the long test and calibration times required by each sensor This is where the consumer heritage of MEMS plays a significant role Highvolume consumer MEMS manufacturers like ST have a huge test and calibration capacity installed and therefore have the ability to produce industrial.

MEMS for Industrial Sensors Efficient MEMS design and manufacturing are the keys to costeffectiveness of sensor applications We live in an increasingly connected world Every imaginable device will eventually be connected to a cloudbased data system to sense everything from air quality to livestock fertility and to provide real time data.
