Why Enclosure Heaters Are Critical in Outdoor Industrial Applications
Introduction Coil and cable heating technology has been so transformational for manufacturing because it itself is so transformational….
Temperature Sensor Tolerances and Temperatures
Tolerances on Initial Values of Emf vs. Temperature NOTE 1 – Tolerances in this table apply to new essentially homogeneous thermocouple wire, normally in the size range 0.25 mm to 3 mm in diameter (No. 30 to No. 8 Awg) and used at temperatures not exceeding the recommended limits of Table 2. If used at higher…

Glossary of Temperature Sensing Terms
Glossary of Temperature Sensing Terms A – L Absolute Zero — Theoretically, the lowest possible temperature. A body at absolute zero would have no molecular motion or heat energy. It is the zero point on the Kelvin and Rankine scales, and is estimated to be -273.15°C or -459.67°F. Accuracy — A statement that is used…
