Intrinsically Safe Explosion-Proof Infrared Temperature Sensor Parameters and Applications

The Intrinsically Safe Explosion-Proof Infrared Temperature Sensor is an online temperature measurement device designed for complex working conditions and environments with high safety requirements. With a compact structure and easy installation, it demonstrates outstanding performance in numerous industrial and scientific research applications.

The sensor adopts the principle of infrared measurement. Through a high-precision optical system and a photodetector, the infrared radiation energy emitted from the surface of the measured object is converted into an electrical signal, which is then transformed into a temperature value according to fundamental radiation laws, outputting a stable 4–20mA signal. Since it uses a non-contact measurement method, operators do not need to approach high-temperature, high-pressure, or high-speed targets to obtain accurate and reliable temperature data. This not only effectively protects personnel safety but also ensures measurement accuracy.

With a fast response time of 300 ms and excellent sensitivity, the sensor can accurately capture transient temperature changes in rapidly changing environments, providing strong support for real-time production monitoring. Its measurement range covers 0–500°C, with an accuracy of ±2% of the reading or ±2.5°C, and repeatability of ±1% or ±1°C, meeting precise measurement requirements across various industrial fields. The sensor also features a 20:1 optical resolution and a fixed emissivity of 0.95, enabling stable measurement performance on different materials and surface conditions.

In terms of safety performance, the product complies with GB3836.1-2010 and GB3836.4-2010 explosion-proof standards, and can operate safely in IIC explosive gas environments. The T6 rating ensures that the device surface temperature does not exceed 85°C, which is particularly critical in flammable and explosive environments such as petrochemical and chemical industries. Its 304 stainless steel housing provides robust protection with IP65 dustproof and waterproof rating, allowing stable long-term operation even in high-humidity or dusty conditions.

In project applications, Intrinsically Safe Explosion-Proof Infrared Temperature Sensor shows excellent performance in power equipment temperature monitoring, enabling safe measurement under high-voltage live conditions and avoiding manual contact risks. In the medical field, it can be used in equipment requiring non-contact temperature detection, ensuring precise data without disturbing the measured object. In the food and construction industries, it enables real-time monitoring of critical temperature points in production processes, helping maintain product quality. In chemical production, it can work reliably in explosion-hazardous areas, providing timely temperature feedback to ensure safe operations. Furthermore, in metallurgy, petrochemicals, light industry, textiles, and scientific research, it is widely applied in detection processes highly sensitive to temperature changes, thanks to its fast response and stable output.

The intrinsically safe explosion-proof infrared temperature sensor not only meets diverse industrial functional requirements but also reflects user-oriented design in detail. The direct cable connection reduces installation steps and space, adapting to different installation environments. It operates normally within a wide ambient temperature range of -40–85°C, and under 10%–95% relative humidity without condensation, making it suitable for extreme conditions ranging from cold to heat, and from dry to humid. These features ensure stable performance across projects in different regions and seasons.
