Today EEP will hit one of the most important temperature sensors used in industrial world which is PT100 temperature sensor.
Do we need to use temperature controller with PT100?
PT100 stands for what? and more

thank you so much ,, excuse me I have a question do RTD need special wire?? or just wire ordinary??

Thank you for your support, no it will be from a specific material depending on operating temperature: conductor / insulation. Temperature Plated copper / PVC. -10/+105 Nickel coated copper/Silicone -50 /+200 Nickel coated copper/Teflon -50/+260 Nickel coated copper/glass fiber -10/+250

Dear sir, I have two questions:- 1- Why do you take the temperature value from the second column (60+2 =62 ˚C)? 2- If the Temperature Trip set point of the winding of the big Motor is 125 ˚C and the Trip set point of the casing is 80 ˚C, do you think we can make two set points for each one? I mean can we make an alarm set point for the winding e.g. 120 ˚C and the Trip set point is 125 ˚C? or do you think the temperature will rise quickly and we cannot make these two points? Thank you and I’m waiting for your reply.

thank you for you support and we are really sorry for being late, 1-This table is used to find out the temperature by using the resistance value, in our example we have 124 ohm so the nearest point in the table to our value is 124.01ohm, using the table we add the temperature value on the same row to the temperature value on the same column 2-Yes, we can make an alarm signal and trip signal, at my work i have a medium voltage motor that have a pt100 with two signals: first an alarm signal on 90 ˚C Second a trip signal on 100 ˚C
