What is pt100 temperature sensor?
A Pt100 temperature sensor is a type of resistance temperature detector (RTD) that uses platinum as a sensing element. It has a resistance of 100 ohms at 0 degrees Celsius and its resistance changes with temperature. Pt100 sensors are commonly used in industrial applications due to their high accuracy and stability over a wide temperature range.
What is difference between 3 wire and 4 wire RTD sensor?
An RTD or Pt100 sensor is connected with two, three or four wires to the measuring device.we learned that we are in fact measuring resistance to determine the temperature. Now when measuring the resistance of the sensing element, we also measure the resistance of the leads and cables used. This gives an error! To compensate for this, the three wire type (bridge) is used, giving enough accuracy in most industrial applications. Even better accuracy is possible with a four wire Pt100 (laboratory applications). Our Pt100 panel mounted indicators have an offset compensation when using two wire sensors.
How do you troubleshoot a rtd?
In an online/live plant, check if resistance is varying or if its showing max resistance or Overload, then RTD needs to be replaced.
How can you check the rtd?
The RTD gives the temperature in resistance unit (Ohm), so you put the RTD in water with ice (0 C/32 F) and you take the reading in Ohm unit in your multimeter, then you put the RTD in boiling water and you take the reading in Ohm. Then you compare the readings according to the table for Temp vs. Resistance to check. It is important that water must be distilled, deionized. Tap water may give false readings as it has minerals. Instead of water test, you can you thermowell which are devices where you program the desired temperature for check RTD and thermocouples. Walter
Where can one find the cheapest RTD sensors?
To find the cheapest RTD sensors check out Grainger store or their website. They have the Tempco brand listed and their prices for those range from $60.00 to $425.00.
