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.

Which type of temperature senseing instrument you use in industry?
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
What is RTD sensor?
Resistance Temperature Difference. Used in thermocouple technology.
What voltage does a Resistor temperature detector put out?
None. An RTD is a passive device. It changes resistance as the temp varies. Your circuit must basically measure the resistance to determine temp. There are many different types of RTD's, each with it's own temperature curve.
How do you conect 3 wire rtd with xtr101?
Three lead RTD is an industrial standard when a bridge arrangement is used. The advantage of this design is it distributes resistance due to the connecting leads equally to the adjacent arms of the bridge making lead resistance insignificant and avoids any error due the same. When it comes matter of using xtr we need to add lead resistance with the R4 as given in the datasheet of texas. This can be done by using a variable resistance for R4 and do change the R4 such that the output current becomes 4mA for lower bound of range.. (ie) (their is no need to use the 3 lead RTD for accuracy same accuracy can acheived here with 2 lead RTD. just by having a variable resistor R4)
Can RTD Cable and Thermocouple cable shall be laid in a common cable tray?
YesYou should be careful with power cables nearby and make sure they are shieldedwww.peaksensors.co.uk
How do you check if RTD pt100 is working properly?
To check if RTD PT100 is working properly you need to check and make sure all the wires are connected. Take several readings and if they are the same, it is working properly.
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.
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.
