The ICP® accelerometers models 354A04 and 354A05 from PCB Piezotronics measure in three spatial axes and offer TEDS - Transducer Electronic Data Sheet - with data on sensitivity, calibration date as well as serial number as standard. Especially for measurements on structures with potential, the sensors are designed with ground insulation. The hermetically welded titanium housings with an edge length of only 21 mm weigh about 14 grams; a through-hole is used for mounting. The electrical connection is made with a ¼-28 inch 4-pin connector and allows the use of standard triaxial measurement cables. The two models cover the measuring ranges 50 g (354A05) and 500 g (354A04) and measure in the frequency range up to 5,000 Hz.
