Hi guys,
I'm currently working on a project where I need to monitor the temperature of molten glass. Does anyone know of a sensor I can use for this purpose.
Thank you
Sean
Normally speaking you would use a pyrometer. I don't know if there is one with an electronic interface.
The sensor mentioned by oric_dan is only for temperatures from -70°C to +380°C. Melting point of glass is way over 380 °C. So that sensor will not suit for the needs described by Sean.
In order to get the exact temperature make sure the sensor has got the feature to adjust the emission coefficient. That allows you to be much more precise in reading the temperature.
Thank you all for the input especially AgeBee I think you pointed me in the right direction.
Would 900°C (1652°F) be enough? I have a pyrometer called "GM900" and it's well-built, has an adjustable emission coefficent and a reasonable price. You can get it on Aliexpress or eBay. No idea how and if you can read out the sensor with the arduino, though.
what about - http://www.lumasenseinc.com/EN/products/infrared-thermometers-and-switches/pyrometer-series-5/pyrometer-impac-is-5.html -
datasheet - Resource Library | Advanced-Energy.com -
Analog output adjustable 0 - 20 mA or 4 - 20 mA
with a resistor you can map that on 0..5V
