The thermometer has a housing made of galvanized sheet steel with a diameter of 63 mm. The measuring system used works according to the principle of the bimetallic coil, which acts directly on the pointer via an axis. The temperature can be read on an aluminum scale with black lettering, which is protected by a glass pane. The housing has protection class IP51 and can be used in limit temperatures from -30 to 80 °C, the nominal position is arbitrary. The device is attached using a brass protective tube with a diameter of 12 mm and a G 1/2 Form A thread according to DIN 3852/2. The immersion tube outlet is axially backwards on the back of the housing. Since no additional auxiliary power is required, the device is ideally suited for energy-saving temperature measurement. Furthermore, it is insensitive to ambient temperature influences. The device can be used universally and is suitable for local temperature measurement.
