The HTS-19A series Piezoelectric Accelerometer is an IEPE triaxial low-noise accelerometer designed for test and measurement applications. It uses piezoelectric ceramics as the sensitive element and has a wide-band response characteristic. This IEPE accelerometer combines high-quality crystals and low-noise microelectronics to achieve ultra-low temperature sensitivity change/response over the operating temperature range compared to other sensitive components; shear mode technology also ensures excellent base sensitivity strain error. The HTS-19A piezoelectric accelerometer uses titanium alloy as the product shell, which is sealed with a lightweight 4-pin connector by laser welding (optional integrated sealed cable output) to ensure low weight and wide bandwidth applications. Excellent amplitude and phase frequency response make this accelerometer ideal for structural testing, component testing, drop testing and general laboratory vibration testing. The cubic structure of the sensor allows test engineers or technicians to easily and simultaneously measure the acceleration of three mutually perpendicular axes, and the test data is reliable and long-term stable.
