connecting O2 sensor straight to Data Logger

[kick2008a]

Is there O2 sensors that you can wire directly to the analogy input on a Qwikdata Logger? We're using a F.A.S.T. WB O2 sensor, but wanted to go directly into the loggers 0-5V or 0-10V input. I wanted to get away from using the controllers on the self contained units.
Thanks,

Yes there is. Any wideband sensor, (not to be confused with an UEGO sensor with a pumping cell), can be used.
The sensor will output a voltage ranging from 35mV to 950mV. The voltage below approx 300mV can be considered to be in the lean range. The voltage output above approx 650mV can be considered to be in the rich range. The actual voltage output is temperature and exhaust pressure sensitive.

The output voltage can be recordeded by any data logger that can read voltage (0-2v), or by a simple volt meter. A data logger is superior since the values may change faster than the eye can follow.

The recorded voltage will be in mV, not Lambda or A/F, since those are calculated values and not actual measured values.
