IEPE® (Integrated Electronics Piezo Electric) sensors are based on the piezoelectric effect. Charge is moved when a force is applied to the piezoceramic. The force is either produced from pressure or seismic mass, when the mass is exposed to an acceleration (F=m×a).
Typical sensors are pressure and acceleration sensors.
The TRION-1850-MULTI module (18 bit, 5 MS/s)
provides up to 20 mA IEPE® current excitation to
achieve high bandwidth at long connection cables.
