The thermometer has a casing made of steel sheet, galvanized, with a diameter of 80 mm. The measuring system used operates according to the principle of the bimetal spiral, which acts directly on the pointer over an axis. The temperature can be read on an aluminum scale with black writing, which is protected by a glass panel. The housing has protection class IP51 and can be used at temperature limits from -30 to 80 °C, the nominal position is random. The device is attached by a protective brass pipe with a diameter of 12 mm and a thread G 1/2 shape A according to DIN 3852/2. The dip pipe branch is Axial toward the back of the housing. Since no additional power supply is required the device is optimally suitable for an energy-saving temperature measurement. Furthermore, it is insensitive to ambient temperature influences. The device can be used universally and is suitable for local temperature measurements.This text is machine translated.
