Using the metaphor of cooking a steak to its desired level of “doneness,” this article examines the difficulties involved in “cooking” forging billets in induction coils to their most uniform level of completion.
Accurate temperature measurements are critical to forging processes and the metallurgical properties of forged components. For a given set of specific conditions, IR temperature sensors work reliably and produce repeatable temperature measurements – but not necessarily accurate ones. Accuracy comes from properly calibrating sensors to the specific materials and applications.
Part I of this article considered the technology of measuring temperature through the infrared radiation of a heated metal mass and some of the misconceptions and inaccuracies that may be present in or about the process. This article will explore ways to improve accuracy through proper calibration and to take temperature measurements of highly reflective bodies.
The TMZ Dual (2TPRG) PC-programmable MODBUS temperature transmitter allows users to increase density and reduce costs with dual RTD, thermocouple, mV, resistance or potentiometer inputs by doubling temperature monitoring capability in a single unit.
Noncontact temperature measurement is a key process metric in many industries, but there are many factors that influence accurate temperature measurement from a pyrometer. Here we look at the common influences on inaccurate temperature measurement.
