Temperature Q&A with JR Madden: Our 3-Wire RTDs Drift and Require us to Recalibrate our Temperature Transmitters

Temperature Q&A with JR Madden: Our 3-Wire RTDs Drift and Require us to Recalibrate our Temperature Transmitters

Q. We have been using 3-wire RTDs in our process for years and are required to check the calibration once every 6 months. Each time we have checked the sensors we’ve noticed they have drifted. This requires us to re-calibrate our temperature transmitters. Do you have something you can suggest to help us reduce the drifting problem we regularly see in these sensors?

Temperature Q&A with JR Madden: What Thermowell and Thermocouple Type Should I Use with my High Temperature Application?

Temperature Q&A with JR Madden: What Thermowell and Thermocouple Type Should I Use with my High Temperature Application?

Q. I have a temperature application that requires a 12-inch thermowell which can withstand a high temperature of 2,000°F. Most of what we have been using becomes brittle and breaks off at the tip. What would you suggest we use, and what type of sensors do you have that will work for us?
