6 answers
Answers:
Maybe omitting to prevent using erroneous reads due to glitches, when using temp-time (pulse analysis) conversion not taking in account the thermal behavior of temp. sensors.
~Dragomir Tch., Research & Development, Sofia, Bulgaria
Yes. Automotive parts heat-treated at improper temperatures due to lack of knowledge about the importance of emissivity when using IR sensors.
~John M, Marketing/Sales, Santa Cruz, CA
I accidentally removed the temperature sensor from my marine aquarium and almost caused the system to over chill.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using temperature sensors?
10 answers
Answers:
Understand what you want to measure, and why. Example: Many technicians want to know the temperature of the flame in a gas-fired furnace....when they really need to know the temperature of the part that is being heated by the flame. This is a big difference!
~John M, Marketing/Sales, Santa Cruz, CA
First, when a buyer wants to purchase a sensor he must know about the purpose of use of that Temperature Sensor. Secondly, accuracy of that sensor.
~Manoj Rout, Marketing/Sales, Rourkela, Orissa, India
Make sure to select temperature sensors within the operating resistance range of the system you are designing.
~Rutherford B, Engineer, New York, NY
Purchase pre-calibrated sensors with standard methodology.

You get what you pay for! You will not see details of the moon's surface with a $5 toy telescope, or win the Indy 500 with a Prius.
~John M, Marketing/Sales, Santa Cruz, CA
Don´t buy the latest model full of non useful gadgets, like new cell phones I use phones to talk!!
~Rodolfo Rodriguez, Almost Engenier. 3 years in Argentina and 3 year in Belgium, Buenos Aires, Argentina
Take precaution to prevent accidental operation of system when in the design or test phase.
~Rutherford B, Engineer, New York, NY
The range of temperature & where it will be used.
