Discussing the need for infrared thermometers to prevent interference
In the use of infrared thermometers, varying degrees to be subject to some interference. In different applications the degree of interference is not the same. This situation brings a lot of trouble to the application of various fields. Therefore, the infrared thermometer for anti-interference measures and in the case of serious interference to solve the problem of interference is a design and development in addition to another key topic.
In front of the interference sometimes let a person can not help, and even can not think of the cause of the problem is interference. Therefore, infrared thermometer in a number of strong electromagnetic wave occasions when the failure, in the exclusion of the instrument itself, the primary reason for consideration is the problem of electromagnetic interference. There was a case: a steel forging customers in the use of my company to provide nine thermometer not long after the reflection of a failure, the customer's own analysis of the reasons, * after the infrared thermometer back to the factory for maintenance, the thermometer back to the factory by the technical after-sales departments to detect all normal, the thermometer back to the customer, the customer installation and testing of the fault remains, through telephone communication may be estimated to be caused by the customer's field interference The company sent a technician on-site processing, to the scene after the technician first check found the pyrometer pyrometer shell induction voltage as high as 20V, and other equipment on the iron material induction voltage is more than 20 volts, there is a high-voltage high-frequency equipment around the estimated source of interference to the pyrometer through the mounting bracket to receive the other equipment came from the source of the huge interference, the technician decisively to take the isolation of infrared pyrometers and other Between the spread of interference between equipment - in the infrared thermometer and mounting bracket in the middle of the rubber pad, and disconnect the circuit board and shell electrical connections, installed after the boot test everything OK, so the fault is eliminated. Other thermometer did not fail to do the same treatment. Customer use so far all normal.
This can be seen from the outside interference on the infrared thermometer's huge impact, sometimes not only on the use of the instrument in the process of the impact of the data, and even serious damage to the instrument.
