An example block diagram of a power unit with IEPE sensors. Furthermore, the IEPE type accelerometers can be popular in the general-purpose testing market, while charge output piezoelectric accelerometers dominate applications where temperatures above about 150˚C are involved.

11/19 · Piezoelectric means ‘with Piezo’ that is when it contains a charge. Capacitive accelerometers are commonly used in hand held devices such as phones, PDAs, tablet computers and gaming consoles. The advantage of capacitive is that it does not require mechanical motion of the finger to be effective; instead the electrical signal provided is an
