Resistance Thermometers Model TWL Exd Applications The resistance thermometers with thread-, flange- or weldon connection are favourably used for the temperature measurement in liquids, solids and gaseous media. The reliable watertightness of these installation methods for gauge pressure and vacuum is an important criteria for selection. Application areas are located in the air-conditioning and cooling industry, the heating-, furnace-, mechanical- and apparatusconstruction as well as in the complete industry. For all applications in hazardous areas, the instruments are supplied with the ignition...
