Pico Technology TA487 IEPE Signal Conditioner
The Pico TA487 signal conditioner lets you connect industry-standard IEPE (integrated electronic piezoelectric) sensors to any oscilloscope or data acquisition device with BNC inputs. The interfacing device is USB-powered, using the cable supplied, and provides a 4 mA constant current source to power a connected IEPE sensor.

Pico Technology TA095 Single-Axis IEPE Accelerometer
The Pico TA095 is a single-axis IEPE accelerometer for a wide range of applications. It can be used with any suitable device that provides a constant-current IEPE power source, such as the Pico TA487 IEPE signal conditioner. The TA095 is available within a kit (PP697). The kit contains a calibration certificate and an introductory guide. Mounting the TA095 can be achieved by using the mounting stud fitted, or by using the optional TA096 mounting magnet available separately as an optional accessory.
