Principals of temperature measurement Principals of temperature measurement Essentially, there are several physically different possibilities of If there is no difference in temperature, both of these contact voltages measuring temperature, such as gas or liquid thermometers, bimetal- cancel each other out. If the points of contact have different tempera- lic strip thermometers, pyrometers, thermal imaging and of course tures, a measurable thermoelectric current starts flowing. thermocouples and resistance thermometers Principals of resistance thermometers The last two are examples known as measuring...

00-TMT Thermocouple assemblies with metal protection tube 00-TMT Thermocouple assemblies with metal protection tube Straight line thermocouple assemblies with metal protection tubes are used, depending on the properties of the protection tube, for common temperature measurements in liquid, gaseous or plastic mediums up to a temperature of 1200°C. The protective fittings of this product line are composed of seam welded or seamlessly drawn metal tubing. Depending on the application, GÜNTHER GmbH has over 40 different, partly high-alloyed materials in a large array of measurements in stock. The...
