Jumo Dial Thermometer, 608540/1080-643-00-0-874-8-106-26-46-150-20/430,5

The Jumo Transformer thermometer with a case made of high quality, UV resistant polyamide (protection class IP 54) has a case diameter of 80 mm. The measuring system used operates according to the fluid expansion principle. The temperature is indicated by a dial on a white scale with black lettering. The device has an accuracy class of 1.5 similar to DIN EN 13190. The temperature can be read in °C or °F through a plexiglas pane (PMMA). The installed microswitch can be set independently to the desired switch off temperature by means of a screwdriver in the front pane. The device is characterized by a high switching point accuracy of +/-0.7 K related to the set switch off point with rising temperature. The maximum permissible switching capacity of the installed changeover contacts is 5 Amp. / 230 Volt AC each. The electrical connection is made via screw terminals and is protected by a cover cap. The switching difference (hysteresis) is approx. 1.5 % of the display range.
