The Infrared Temperature Transmitter Measures Non-contact And Ensures High Accuracy

An infrared temperature transmitter is an industrial instrument that uses an infrared thermopile sensor to measure the surface temperature of an object non-contact and convert it into a standard electrical signal (such as 4-20mA) for output.

• Non-contact measurement, does not interfere with the measured target and does not damage the object
• Extremely fast response speed (ms level)
• Can measure moving, rotating, high-temperature, and electrified objects
• Not affected by medium contamination or corrosion
• Long-distance measurement, suitable for dangerous and inaccessible locations

• High-temperature moving objects: steel rolling, rotating shafts, molten metals
• Electrical equipment: high-voltage busbars, transformers, motor coils
• Flammable and explosive hazardous environments: chemical industry, oil and gas
• Food and pharmaceuticals: non-contact aseptic temperature measurement
• Heating and forming processes of glass, plastics, rubber, etc.

Infrared temperature transmitters are professional tools for solving non-contact temperature measurement problems, especially in high-temperature, moving, dangerous or clean environments, where they have irreplaceable advantages. Their measurement accuracy highly depends on the correct handling of emissivity and the guarantee of the optical path.

The optical fiber temperature transmitter is an intelligent instrument that converts the temperature signal detected by the optical fiber temperature sensor into a standard electrical signal (such as 4-20mA) or digital signal, and has functions of signal processing, isolation, transmission and communication.

1. Resistance to strong electromagnetic interference (EMI): It is not affected by high voltage, strong electric fields, magnetic fields, or lightning, which is the most core advantage.
2. Intrinsic safety and explosion-proof: The probe is free of electricity and sparks, making it suitable for use in Zone 0 flammable and explosive environments.
3. Excellent insulation performance: It is the preferred choice for temperature measurement in high-voltage electrical equipment.
4. Corrosion and high-temperature resistance: The optical fiber material has strong chemical stability and can adapt to harsh corrosive environments.
5. Long-distance transmission: The signal can be transmitted for several kilometers without attenuation.
6. Multi-point temperature measurement: A single optical fiber can be connected to multiple temperature measurement points.

• High-voltage electrical equipment: transformer windings, GIS switch cabinets, cable joints
• Strong electromagnetic environments: substations, photovoltaic inverters, motors
• Chemical explosion-proof areas: reaction vessels, storage tanks, oil and gas pipelines
• Nuclear power, metallurgy and other strong radiation and strong interference environments

Overall, the optical fiber temperature transmitter is an expert with a specific area of expertise. Its selection logic is very clear: when the measured environment has high pressure, strong magnetic fields, flammable and explosive substances, or when the space is narrow and traditional sensors cannot be installed, it is an irreplaceable solution.
