Particle Sensor using Solidly Mounted Resonators

particle sensor using a paddle-type silicon cantilever and the use of thin-film piezoelectric on silicon resonators has been proposed by Harrington . et al. [13]. Thermally actuated MEMS resonators were demonstrated for the mass measurement of airborne particles [9, 14] and the use of such structures within aerosol impactors for the size separation of particles have been proposed as well [15, 16]. The …

09/07/2021· A sensor is generally intended to produce a variable signal over some measurement range as opposed to a switch which generally acts in a binary fashion, as in on or off. While this is not always true it helps when it comes to deciding between sensors or switches. For example, a level switch can detect when a certain specified level in a tank has been reached and signal a pump to stop running. A …

A PARTICLE SENSOR AND PARTICLE SENSING METHOD - …

A particle sensor uses an electrostatic particle charging section in the form of an ionization chamber. A flow sensor arrangement is used to produce a signal which is representative of the amount of gas flow between the outside of the ionization chamber and the inside of the ionization chamber. This information is indicative of the flow conditions, and can be used to determine when adverse flow conditions are …
