Thermocouple Calibration
Thermocouples Thermocouples measure temperature and are used quite often in process controls. How They Work When wires of two different thermoelectrically homogeneous materials are joined at one end and placed

Temperature Measurement
What Temperature are Celsius and Fahrenheit Value Same ?
Simple Conversions of Celsius and Fahrenheit Temperature Scales 1. Standard Conversion °F to °C : Deduct 32, then multiply by 5, then divide by 9 °C to °F : Multiply by
Thermocouple Calculations
The voltage generated by a thermocouple is a function of the temperature difference between the measurement and reference junctions. Traditionally the reference junction was held at 0 °C by an
Liquid In Glass Thermometer Principle
The liquid in glass thermometer, is the most commonly used device to measure temperature and it is inexpensive to make and easy to use. The liquid in glass thermometer has
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 be thought of as a thermally conductive protrusion into a
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 a graphic display of objects in its view according to
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 sensor from the target object’s surface. This is counterintuitive to
Non-contact Temperature Sensors
Virtually any mass above absolute zero temperature emits electromagnetic radiation (photons, or light) as a function of that temperature. This basic fact makes possible the measurement of temperature by analyzing
Thermocouples Burnout detection
The most common failure mode for thermocouples is to fail open, otherwise known as “burning out.” An open thermocouple is problematic for any voltage-measuring instrument with high input impedance because
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 junction’s existence. When you form a complete circuit of dissimilar
