June 23, 2011 – Dytran Instruments introduced the 3274A series of miniature, low profile, IEPE piezoelectric accelerometers designed to mount in spaces typically inaccessible to other types of accelerometers. Available in three different models with sensitivities of 5 mV/g, 10 mV/g and 25 mV/g, the 3274A series feature a shear sensing element packaged in a lightweight, teardrop titanium housing. Units are ideal for the measurement of shock and vibration of very 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 just 0.24 inches and weigh 2 grams.
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 family of accelerometers utilizes 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 utilize 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 3274A series is hermetically sealed for reliable operation in high-humidity and dirty environments and case isolated to avoid EMI/ground loop interference. Priced at $568.
