JUMO 00512083

The transformer thermometer with a housing made of high-quality, UV-resistant polyamide (protection class IP 54) has a housing diameter of 80 mm. The measuring system used works on the principle of liquid expansion. The temperature is indicated by a pointer 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 through a plexiglass disc (PMMA) in ° C or ° F. The built-in microswitch can be set independently of one another to the desired switch-off temperature using a screwdriver in the windscreen. The device is characterized by a high switching point accuracy of +/- 0.7 K based on the set switch-off point when the temperature rises. The maximum permissible switching capacity of the installed changeover contacts is 5 amps / 230 volts AC. The electrical connection is made using screw terminals and is protected by a cover cap. The switching difference (hysteresis) is approx. 1.5% of the display range. After falling below the switch-off temperature, the microswitch automatically switches back to its original state. The contact adjustment is protected against improper adjustment by a cover, the thermometer is also equipped with a drag pointer so that the maximum process temperature reached is recorded. The device has an immersion tube with a diameter of 8 mm made of stainless steel (material no. 1.4571) and a screw connection made of brass. The attachment is made by a thread G 1 form A according to DIN 3852/2, the nominal position is max. 90 °. The thermometer is used in particular in the transformer industry, but is also universally applicable for local temperature measurement of any kind. A decisive advantage is that no additional auxiliary energy is required for temperature measurement. The device is RoHS compliant and cadmium free.
