Subject: RE: Does a Bosch LSM-11 use a converntional heater element?

[Lowell Foo]

I run a Motec on my daily driven Talon turbo and the sensors last
about a year which agrees with the sensors ~500 hour lifespan.
Without the heater connected the sensor will not show a reading
so I leave it on.  I'm using a Bosch 0 258 104 002 which seems
to be an updated part # from the older LSM-11 but not sure if
there's any difference.  The sensor is mounted downstream of the
turbo so EGTs are just around the upper range of what the sensor
is rated for.

Anyone else on the list have a Motec?

After searching some more I found something at Motec's Korea site:
http://www.moteckorea.com/pdf/x03.pdf It looks like it is good enough for
motec to run the sensor without heater control. It looks like their heater
control is something like: -If you expect more then 800ºC exhaust
temperature, don't connect the heater...

It looks like ETAS uses the the cell resistance to control the heater in
their LA2 lambda meter.

But still, has anyone got some data for the LSM 11 and its temperature
dependence?
