I have a Eurotherm panel mounting temperature indicator - the standard sized 95mm x 48mm front panel often seen in process instrumentation. Most of the type number and s/n are obliterated but in the past some kind soul has written 0/1999 Pt Rh TOH ( that H could be a greek mu) so I assume it is intended for a Platinum / Platinum Rhodium resistance element with a range of 0 to 1999 deg C. Needless to say I don't have the sensor element !
But looking at the RS site I see two types, 100 ohm and 1000 ohm - is there any way of telling which type is right for this instrument?
Shame really as I would much prefer it to be a 'type K' as I want to measure lowish temps (20 - 50 deg C)
Any clues welcome.
