Thermowells and Thermocouples are one of the most important and the most common ones that
you are going to find out from a THERMOWELLS AND THERMOCOUPLES SUPPLIERS IN EGYPT. There
are others which could be confused with it like a thermistor would have like a two wire connection.
Identifying these types of devices can be straightforward if you understand the terminology. One key
term you’ll encounter is RTD, which stands for Resistance Temperature Detector. This term broadly
defines this category of temperature sensors. Additionally, THERMOWELLS AND THERMOCOUPLES
SUPPLIERS often use specific color codes to differentiate their sensing elements. For instance, you
might find one sensing element marked in red, while others could be indicated with black and green
colors.
RTD Electrical tests
One of the things you can do is test by checking the probe in an ice bath which requires an ohm
meter and some crushed ice and some kind of an insulated container and testing. If you should end
up if it is a class, a probe which is the tighter tolerance. The tighter the manufacturing tolerance plus
or minus 0.06 ohm and the class b is 0.12 ohms. If you don’t have an ice bath you can just check the
probe if it is at a roughly room temperature. You can measure between the white lead and the red
to get a more accurate measurement; you can manually eliminate the lead resistance.
