22 TITANS | TT-0001-1U27
The TT-0001-1U27 belongs to the 22 TITANS U-Series and is a triaxial IEPE shock accelerometer for impact and transient acceleration measurements. Its piezoelectric ceramic shear structure provides a broad frequency response and high resonance frequency. Built-in low-impedance electronics provide voltage output for three measurement axes.
The laser-welded titanium alloy housing measures 15 × 15 × 10 mm with a typical mass of 8.5 g. A central Ø4.1 mm through-hole supports installation around a mounting bolt and orientation around the mounting point. This variant uses 3 × M5 connections.
Typical applications include lightweight and mediumweight shock-table measurements and transient impact testing. Resolution, resonance frequency, time constant, noise, temperature response and mass are typical values. Shock and vibration limits describe mechanical survival in a non-powered condition. A dash denotes a parameter not specified by the manufacturer.
