Strong electromagnetic interference environment can use fiber optic temperature measurement

Fluorescent fiber optic temperature measurement system applied to power equipment monitoring system, anti-strong electromagnetic interference, high pressure resistance, fiber-optic end probe attached to the surface of the body under test, temperature measurement fiber immune to electromagnetic field interference, high-voltage insulation, flame-proof and explosion-proof; single-point temperature measurement, digital signal output; fiber-optic probe diameter is small, can be customized; easy to install; toggle switches, can be set directly to the communication address. In addition to a wide temperature measurement range and accurate, reliable temperature measurement performance, there are excellent anti-EMI/RFI (electromagnetic interference/RFI) characteristics, high-voltage insulation and anti-interference and other excellent performance. Real-time and accurate monitoring of hot spot temperature during dynamic load operation can be realized. Solve the problem of low security, poor measurement accuracy, temperature measurement failure and other issues in the electromagnetic environment using traditional electrical temperature measurement instruments.

Due to some temperature measurement site has a harsh environment, such as high temperature, high pressure, high electromagnetic interference, and even some temperature measurement site has a certain degree of corrosivity, radioactivity; or flammable and explosive, etc., is not suitable for electronic temperature measurement equipment in the field work. In order to solve the above problem of temperature measurement in harsh environments, many long-distance temperature measurement equipment is designed, such as: long-distance infrared temperature measurement equipment, long-distance wireless temperature measurement equipment. However, these electronic devices have some critical shortcomings, such as infrared temperature measurement equipment is susceptible to space light interference, can not be automatically measured in real time, can not enter the space of the narrow temperature measurement point, produce sparks and so on. The temperature measurement node of wireless temperature measurement equipment is susceptible to on-site electromagnetic interference, greatly affecting the accuracy of temperature measurement, or even unable to carry out temperature measurement, and at the same time does not have the ability to resist corrosion and radiation.

Fluorescent fiber optic sensors can be in a strong electromagnetic interference environment for accurate temperature measurement, fiber-optic end probe attached to the surface of the body under test, temperature measurement fiber immune to electromagnetic field interference, high-voltage insulation, flame-proof and explosion-proof; single-point temperature measurement, digital signal output; fiber-optic probe with a small diameter, can be customized; easy to install; toggle switches, can be set directly to the communication address. Real-time collection of temperature information of the measured object. The use of Huaguang Tianrui fluorescent fiber optic temperature measurement probe has a strong electromagnetic immunity and voltage resistance, insulation properties. Sensitive temperature sensing, long-term stable and reliable operation. Temperature measurement accuracy up to ± 1 ℃.
