A few questions:
1) Are you measuring the temperature of one bit of track or are
attaching the logger to a train and measuring the temperature of the
track on it's journey
2) Do you have a power supply available
3) Do you want to record any other information (time, passage of
trains, etc.)
1. Mounted next to the track for a week or so at a time.
2. No power, it'll have to have batteries.
3. Other info: time.
It would be handy to be able to measure the passage of trains (in case
temperature suddenly increases when a train passes, then gradually
dissipates), but I'm not sure how easy/difficult that would be.
The logger would have to be small enough to be used in tunnels.
(fix top posting, this time)
Is anyone else surprised that network rail or whatever they are caled
nowadays is asking on usenet for where to get tools from? Or is this for a
model railway?
