IEPE Signal Conditioner
The TA487 IEPE Signal Conditioner is a solution for BNC-interfaced oscilloscopes. It is a simple adaptor that allows any PicoScope with the ability to measure and capture signals from a large selection of piezo-electric IEPE sensors.
Integrated Electronics Piezo-Electric (IEPE) is the technical standard for piezo-electric sensors that include built-in active conversion to boost the high-impedance signal through long lengths of cable with minimal noise. IEPE sensors, such as acceleration, force and pressure transducers, are widely used across a variety of industries, including automotive.
Using the TA487 is as simple as connecting an IEPE sensor and the included USB cable into the TA487, and then attaching the TA487 to a PicoScope or any BNC oscilloscope to capture data from the piezo-electric sensor. The TA487 provides a safe constant 4mA current power source to the sensor, allowing it to work over long cable lengths while still providing a good signal to noise ratio.
