Accelerometers Monitor Three Orthogonal Directions

The Series 354B family of tri-axial ICP ceramic shear accelerometers is capable of simultaneously measuring vibration in three orthogonal directions. The Model 354B20 specifies a sensitivity of 2.5 mV/g with a 2 kg measurement range while the Model 354B21 exhibits a sensitivity of 10 mV/g with a 500 g measurement range. The third member of the family, Model 354B22, provides a 100 mV/g sensitivity with a 50g measurement range. Each sensor integrates three separate, hermetically sealed titanium-cased, single-axis sensors that are permanently mounted on a hard-anodized mounting block. Additionally, each component features three individual 10-32 coaxial connectors. Other shared features include signal conditioning circuitry, bolt mounting, the ability to withstand shock inputs up to 5 kg, and an operating temperature range from -54°C to +121°C.
