PTAF2 v PTAFlite

What is the difference between PTAF2 v PTAFlite? I'm using Nihon Kohdon if that makes a difference. I'll be using a seperate snore mic too. Thanks a lot.

Disclaimer: I work at Philips Respironics, came over from Pro-Tech where I did the tech support for all Pro-Tech products.
The PTAF 2 is a differential pressure transducer, meaning you can use an adapter and put it in the CPAP circuit to monitor patient airflow with it. Also can be connected to DC or AC inputs on almost any acquisition system by using a different cable. Uses a 9 Volt battery, change every month.
The PTAF Lite is a piezo powered single port pressure transducer that can only connect through AC inputs, must be mindful of the filter settings. Can connect into a CPAP circuit, but the resulting waveforms are not pretty.
With NK it would be best to use the PTAF 2.
