CIENTIFIC
The weighing principle used in the tapered element oscillating
microbalance (TEOM) TEOM mass transducer (Figure 1-2) is similar to
that of a laboratory microbalance in that the mass change detected by the
sensor is the result of the measurement of a change in a parameter (in this
case, frequency) that is directly coupled via a physical law (or from first
principles).
