608550 / 1080-643-0-874-8-106-26-46-150-20 / 430.4, thermometer, display range -20 to 120 ° C, installation length 150 mm, 1 switching contact

Thermometer, display range -20 to 120 ° C, installation length 150 mm, 1 switching contact

The hand contact thermometer with a stainless steel case (material 1.4301, 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 an acrylic glass pane (PMMA) in ° C or ° F. The built-in microswitch can be adjusted to the desired shutdown temperature with the help of a sensor 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 change contact 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 dipping tube with a diameter of 8 mm from CuNi and a brass screw. The mounting is done by a thread G 1 Form A according to DIN 3852 / 2, the nominal position is arbitrary. 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.
