PCB Piezotronics, Inc. Triaxial ICP® Accelerometer TLD356A16

The TLD356A16 Triaxial ICP¬Æ Accelerometer from PCB Piezotronics, Inc. features a sensitivity of 100 mV/g and a measurement range of ¬±50 g pk. It operates within a frequency range of 0.5 to 5000 Hz for the y and z axes, and 0.5 to 4500 Hz for the x axis, with a resonant frequency of ,â 25 kHz. The device exhibits a non-linearity of ,⧠1% and a transverse sensitivity of ,⧠5%. Designed for a wide temperature range from -65 to +176 ¬8F (-54 to +80 ¬8C), it has an overload limit of ¬±7000 g pk. The accelerometer requires an excitation voltage of 20 to 30 VDC and a constant current excitation of 2 to 20 mA. Its output impedance is ,⧠200 Ohm, with an output bias voltage of 8 to 12 VDC. The spectral noise levels are low, with 40 ¬µg/,àöHz at 1 Hz and 0.5 ¬µg/,àöHz at 10 kHz. The sensing element is ceramic with a shear geometry, housed in anodized aluminum and sealed with epoxy. The dimensions are compact at 0.55 in x 0.80 in x 0.55 in (14.0 mm x 20.3 mm x 14.0 mm) and it weighs 0.26 oz (7.4 gm). The accelerometer includes a 1/4-28 4-pin electrical connector positioned on the side and a mounting thread of 10-32 female. Optional versions are available, including TEDS capabilities for digital memory and communication compliant with IEEE P1451.4.
