PCB Piezotronics supports design, research, and development efforts with precision accelerometers for the measurement of vibration, shock, acceleration, and motion. In addition to miniature precision units, PCB's rugged accelerometers are used for monitoring and evaluation of all types of equipment and structural performance. Such applications usually require proof of calibration of the entire measurement system, from sensors to final output. The most commonly used technology is ICP (IEPE) accelerometers, which require ICP power. (ICP sensors can be referred to as IEPE or voltage mode output sensors). Most modern data acquisition, digital control, and portable data systems provide ICP sensor power.
In these devices, each directional axis measured requires one channel of the data system or signal conditioner. Single-axis and three-axis (triaxial) accelerometer configurations include specifications on sensitivity, temperature, frequency response, amplitude response, form factor, and lead wire grounding.
The new TLD356A01 and TLD356A03 ICP triaxial accelerometers feature the addition of TEDS to minimize errors from manual sensitivity entries, reducing setup time. These miniature, lightweight, durable ICP triaxial accelerometers feature a wide frequency range, from 2Hz to 8kHz (x axis), 2Hz to 5kHz (y & z axis), and a high resonant frequency ≥ 50,000Hz.
The TLD356A01 and TLD356A03 are primarily used to measure vibration inside devices where space is restricted. Applications include electronic device design validation, automotive systems development, modal and structural analysis, ESS and HALT/HASS testing, space restricted installations, device and small component qualification testing, vibration testing on small objects, and general purpose vibration testing.
TEDS is an acronym that stands for transducer electronic datasheet and was developed by the Institute of Electrical and Electronics Engineers (IEEE) as part of their “smart transducer” standard for sensors and actuators. It is an EEPROM device embedded in the sensor or sensor's connector that contains information such as serial numbers, calibration dates, and other calibration factors. TEDS allows sensors to act in a truly “plug and play” fashion, eliminating some or all manual entry during setup and ensuring that the correct settings are applied. The stored information can be read by the measuring system when the sensor is connected, simplifying the sensor setup. Because it's an open standard, TEDS devices should be cross-platform and interchangeable regardless of manufacturer.
