RE: Temperature Monitoring

Nick,

Voltage-based sensors are quite common in industrial applications,
unfortunately it usually leads to "industrial" price :-(

However, I had a quick Google and came up with the following:
http://www.newport-scientific.com/HumidityAndTemperatureTransmitter.htm
(no direct prices & not desperately pretty, but 0-5V output :-)  )
http://www.process-controls.com/Alpha/Rotronic_Humidity_Temperature_Tran
smitters.htm (again, no prices)
http://www.analog.com/en/prod/0,,774_868_5B35,00.html
(circuit to accept
an industry-standard 4-wire RTD and give out 0-5V)
http://www.ecomfrontier.com/asi/member/product.asp?Dept%5FID=168&Pf%5FID
=XCAT1 (accepts RTD or thermocouple inputs)

Hope that helps, let us know how you get on,

Cheers,

Tim H.
