608540 / 1080 -643-0-874-8-106-26-46-150-20 / 430.5, trafo thermometer, -20 to 120 ° C, 150 mm, 1 switching contact

Trafo thermometer, -20 to 120 ° C, 150 mm, 1 switching contact

The transformer thermometer with a housing made of high-quality, UV-resistant polyamide (protection type IP 54) has a housing diameter of 80 mm. The measurement system used works according to the fluid expansion principle. The temperature is shown by a pointer on a white scale with black marking. The device has a precision class of 1.5 similar to DIN EN 13190. The temperature can be read by a plexiglass disc (PMMA) in ° C or ° F. The built-in microswitch can be adjusted to the desired shutdown temperature independently of each other by means of a screw-in-the-windscreen. The device is characterized by a high switching point accuracy of + / -0.7 K in relation to the set off point at rising temperature. The maximum permissible switching power of the installed exchange contacts is 5 Amp. / 230 Volt AC. The electrical connection is made via screw terminals and is protected by a cover cap. The switching difference (hysteresis) is about 1.5% of the display range. The microswitch automatically switches back to the original state after the switch-off temperature is below. The contact adjustment is protected against improper adjustment by a cover, the thermometer is also equipped with a treadmill, so that the maximum process temperature is recorded. The device has a diving tube with a diameter of 8 mm of stainless steel (material no. 1.4571) and a brass screw. The mounting is done by a thread G 1 form A according to DIN 3852 / 2, the nominal position is max. 90 °. The thermometer is used especially 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.
