Temperature brake to reduce the reaction speed of a temperature cable sensor in a fridge or freezer avoids larger temperature changes (and thus false alarm), e.g. by the frequent opening the refrigerator door for temperature sensor with 5 mm diameter.If a well in a constant low temperature range must be stored, helps a thermometer with cable sensor and alarm function for controlling the refrigerator or freezer. The temperature is not within the programd limit values, you will be made aware. But already opening the refrigerator door leads to a short-term temperature changes. Especially for cooling and freezers, the commercially used and frequently and need to be closed, it can be so easy to false alarms. The TFA reference body made of aluminum is used as a "Temperature" brake and helps to avoid this. The sensor of the cable sensor, fixed and in close proximity to be monitored in the reference body well placed. Only when the temperature of the reference body react to changes, also the se
