美的空调温度传感器规格表(国外英文资料) Specifications of air conditioning temperature sensors in the United States The temperature characteristics of the air conditioning temperature sensor are very important parameters. If the temperature characteristics do not meet the requirements, it is easy to cause air conditioning malfunction, so that the air-conditioning can not work as required. But there are many types of temperature sensors and different suppliers of the same type. In order to facilitate the relevant departments to correctly judge the performance of the temperature sensors at the scene, the following matters are summarized as follows: Room temperature pipe temperature sensor: room temperature sensor is used to measure indoor and outdoor environmental temperature. The tube temperature sensor is used to measure the tube wall temperature of evaporator and condenser. The shape of the room temperature sensor and the tube temperature sensor are different, but the temperature characteristics are basically the same. According to the temperature characteristics, there are two types of room temperature pipe temperature sensors used in the United States today: 1. The constant B value is 4100K + 3%, the reference resistance is 25, and the corresponding resistance is 10K = 3%. The higher the temperature, the smaller the resistance; the lower the temperature, the greater the resistance. As far as 25 degrees Celsius is concerned, the tolerance range of the corresponding resistance is greater; at 0 and 55 DEG C, the corresponding resistance tolerance is about 7%; and below 0 DEG C and above 55 DEG C, there will be a certain difference in resistance tolerance for different suppliers. Enclosed is the table of the temperature and resistance of the New South Korea sensor (the middle is the nominal value, the minimum is the maximum): 0 C - (32.8812 - 35.2024 - 37.6537 - 5 C, K); (25.3095 - 26.8778 - 28.5176 - 10 C, K); (19.6624 - 20.7184 - 21.8114 - 15 C, K); (15.4099 - 16.1155 - 16.8383 - 20
