Continuous Flow Measurement
The Continuous measurement of fluid flow is arguably the single most complex type of process variable measurement in all of industrial instrumentation.
Temperature Sensor Accessories
One of the most important accessories for any temperature-sensing element is a pressure-tight sheath known as a thermowell. This may
Thermal Imaging Temperature Measurement
A very useful application of non-contact sensor technology is thermal imaging, where a dense array of infrared radiation sensors provides
Non-contact Pyrometers Characteristics
An interesting and useful characteristic of non-contact pyrometers is that their calibration does not depend on the distance separating the
Non-contact Temperature Sensors
Virtually any mass above absolute zero temperature emits electromagnetic radiation (photons, or light) as a function of that temperature. This
Thermocouples Burnout detection
The most common failure mode for thermocouples is to fail open, otherwise known as “burning out.” An open thermocouple is
Problems of Reference Junction Compensation : Thermocouples
Reference junction compensation is a necessary part of any precision thermocouple circuit, due to the inescapable fact of the reference
Thermocouple Extension Wires
In every thermocouple circuit there must be both a measurement junction and a reference junction: this is an inevitable consequence
Thermocouple Software compensation
Previously, it was suggested that automatic compensation could be accomplished by intentionally inserting a temperature-dependent voltage source in series with
Thermocouples Law of Intermediate Metals
It is crucial to realize that the phenomenon of a “reference junction” is an inevitable effect of having to close
