how u meassure a room temp?in rtd or themo couple?

Answer Posted / prasad

By checking it's RESISTANCE , 100 ohm is equal to o degree Celsius.
Put in formula

R(new)=R0(1+at),
R(new)-resistance unknown temperature,
R0-resistance at 0 degree,
a-coefficient of thermal(0.00395),
t-Temperature unknown,



You got R(new) by measuring Resistance at room temperature,
you know R0-100 ohm ,then calculate that is room temperature.

I was working on calibrating turbidity transmitters endress+hauser at effluent polishing plant.We calibrated using NTU buffers.What happened is that when we immersed the sensor, everytime we raise and lower the sensor gradually, the reading will vary.my question is that is there any specifications on what is the required distance from the bottom of the container with buffer to the face of the sensor?Is it ok to install the sensor in a medium which has turbulence specially if bubbles are present?
