Measuring Temperature
Rob.Wilson:
Hi Lads a spot of help needed
I need some way of measuring the temperature in a temporary core oven i am going to knock up ,,250C max ,,,,,,,,, I saw some were a set up with a multi meter and two wire wound together :scratch:,,, any idea what type of wire ? and how do you calibrate it ? . or dose anyone have a better idea
Thanks Rob

There are a number of ways of measuring temp...
Optical pyrometer..( I guess you aint got one to hand....) or there is the simple thermocouple...
A thermocouple is made by twisting together two disimmilar metal wires ( Iron/Constantan) that will generate an emf proportional to temperature...( Its called the Seebeck effect... I'm a tiffy by trade..)
A standard dvm from Maplins should suffice for measuring the voltage 'though you may need tables to convert from volts to degrees( unlesse the dvm has a t/c input..! )
Have a look here: http://www.tc.co.uk/ I use this company at work, let me know if you have any queries. :thumbup:

I got one of these .. or similar .. comes with a (type K ??) thermocouple

Up to circa 900 c IIRC
Will look if interested ..
Quite surprised how accurate it was .. about +/- 6 C at 800 C Checked by a mate in the test labs @ RR
