IEPE Signal Conditioning Amplifiers
Although IEPE (Integrated Electronics Piezoelectric) sensors is not a new technology there are a wide variety of applications where the measurement instrumentation is not configured with IEPE signal conditioning built in. In these situations it is necessary for the IEPE supply to be provided by an external source. Usually this type of instrument will also provide th user with the option to add gain to the signal being conditioned. The Kemo range of IEPE signal conditioning instruments can be used as stand alone conditioners/amplifiers are many of them can also be integrated with filters.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-02 And WMA-02LF
The Falco Systems WMA-02 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 4mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-02LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.2mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.
