Dytran Instruments 3274A series piezoelectric accelerometers

Click2Contact

The 3274A series miniature, low-profile, IEPE piezoelectric accelerometers are designed to mount in spaces typically inaccessible to other types of accelerometers.

Available in three different models with sensitivities of 5, 10 and 25 mV/g, the 3274A series accelerometers feature a shear sensing element packaged in a lightweight, teardrop titanium housing. The units are suitable for the measurement of shock and vibration of small, lightweight objects such as printed circuit boards and board-mounted components. Designed for adhesive mount, the Dytran 3274A series have an upper frequency response of 10,000 Hz, an overall height of 6 mm and weigh 2 g. Due to their low mass and high crystal stiffness, units have a resonant frequency of >40 kHz, allowing them to be used to measure high frequency vibration with very little error.

The Dytran 3274A series accelerometers utilise IEEE 1451.4 Transducer Electronic Data Sheets (TEDS). This function allows the user to query individual sensors within a large array of sensors during a field test, as to model number, serial number, sensitivity and other attributes using a TEDS-compatible signal conditioner/data acquisition system.

Units utilise a specially designed 3-56 coaxial connector, mating with a field-replaceable coaxial cable, model 6003A03, and terminating to a 10-32 jack (supplied). The accelerometers are hermetically sealed for reliable operation in high-humidity and dirty environments and case isolated to avoid EMI/ground loop interference.
