APPLICATION SELECTION GUIDE
INTRODUCTION
Temperature devices in process manufacturing environments provide measurements to
the process plants’ control systems. The performance of these temperature instruments
is often critical to optimized operation of the process manufacturing plant or proper
functioning of the plant’s safety systems.
Process temperature instruments are often installed in harsh operating environments,
causing their performance and the performance of their sensors to shift or change over
time. Keeping these devices measuring temperature within expected limits requires
periodic verification, maintenance and adjustments.
