This article mainly introduces "what is the infrared temperature sensor detection transmitter scheme". In the daily operation, I believe that many people have doubts about the infrared temperature sensor detection transmitter scheme. The editor consulted all kinds of data and sorted out the simple and easy-to-use operation methods. I hope it will be helpful for everyone to answer the doubts about "what is the infrared temperature sensor detection transmitter scheme?" Next, please follow the editor to study!

In the operation process of high voltage transmission line, infrared temperature sensor is usually used to detect in order to better grasp the operation state of high voltage transmission line.

The scheme of infrared temperature sensor detecting transmitter:

1. The working principle of infrared temperature sensor:

In nature, all objects with temperatures above absolute zero (- 273 ℃) will constantly emit infrared energy in the form of electromagnetic waves. The optical system in the infrared temperature sensor can collect the infrared radiation energy emitted by the measured target, and then concentrate it on the photosensitive surface of the photodetector and convert it into the corresponding electrical signal; after the signal is processed by the amplifier, it is corrected according to the algorithm developed by the instrument and the target emissivity, and converted into the temperature value of the measured target.

Second, the advantages of infrared temperature sensor:

Compared with conventional temperature sensors such as thermocouple and thermal resistance, the infrared sensor does not come into direct contact with the measured object when measuring the temperature; on the contrary, it calculates the surface temperature of the high voltage transmission line by measuring the infrared radiation intensity emitted by the high voltage transmission line. there is no need for power outage, and it has the advantages of high sensitivity and fast response.

The infrared temperature sensor can measure the infrared radiation energy in the range of 8 ~ 14 μ m in a non-contact way, and the optical resolution is 20:1, that is, the distance ratio between the measuring point of the sensor and the diameter of the measured object is 20:1.

Third, the infrared temperature sensor detects the technical parameters of the transmitter:

Transmitter circuit operating environment: 0: 60 ℃, 10: 95% relative humidity (non-condensing)

Response time: 150 milliseconds (95%) or 300 milliseconds (95%)

Temperature range: 0-100 ℃, 0-150 ℃, 0-200 ℃, 0-300 ℃, 0-400 ℃, 0-500 ℃ (default is 485), 0-600 ℃ (default is I20), 0-800 ℃, 0-110 ℃

Practice has proved that many equipment accidents start with abnormal heating at first. if these equipment are in a state of high load for a long time, the phenomenon of temperature rise will often occur, which is imperceptible to the human eye at first. it eventually leads to thermal failure when the temperature accumulates.

In a word, the infrared temperature sensor can express the detected equipment temperature and other abnormal events in the form of digital signals through combination networking, cloud computing and other technology. it can effectively help power workers to solve the thermal faults and defects in the operation of substation equipment and ensure the healthy operation of electrical equipment.

At this point, the study of "what is the scheme of infrared temperature sensor detection transmitter" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
