Some processes do not require temperature measurement accuracy, and others do.
However, you may be unsure whether accuracy is important for your particular application,
or whether improving accuracy will make enough of a difference in your process
results to justify the cost and effort. This paper identifies problems that result from
inaccurate measurements and outlines ways to solve them that are both effective and
Temperature measurements can be categorized into three groups:
- Those which do not require accuracy. You simply need to know if the
temperature is stable or going up or going down.
- Those which do require accuracy. Strategies in this paper will help with those
- Those where there is uncertainty about the accuracy requirement. If the
measurements in this category are on a Preventive Maintenance schedule for
calibration or verification you may want to take steps to improve accuracy. The
same steps we take to achieve higher accuracy also result in reduced drift and
that would have a positive impact on your maintenance frequency.
Improving accuracy and reducing measurement drift are often related and can have
measureable results. This paper shows how to:
- Select the best sensor for the application
- Reduce errors caused by external environment
- Reduce errors caused by lead wires
- Reduce measurement errors
