High Precision RS485 Infrared Temperature Sensor

Infrared temperature sensor is an intelligent industrial grade sensor based on non-contact temperature measurement principle and using RS485 digital output. The product is centered around a high-sensitivity array temperature probe and integrates Modbus RTU communication protocol to maintain excellent linearity and measurement stability over a wide temperature range. It is suitable for integration scenarios of various devices that require real-time temperature monitoring, such as power, HVAC, metallurgy, and heat treatment.

Core Advantage：

• Wide range, high precision - The sensor provides multiple temperature ranges of -50~1200 ℃ (default 0-600 ℃), with an accuracy of ± 1% or ± 1.5 ℃ of the measured value, meeting diverse industrial needs from low to high temperatures.
• Excellent optical performance - optical resolution reaches 20:1 (D: S), spectral response covers 8-14 μ m, allowing for measurement of smaller targets at longer installation distances. The emissivity is fixed at 0.95, effectively reducing reflection interference.
• Digital communication, stable and reliable - standard RS485 interface, supports Modbus RTU protocol, default baud rate of 4800bps, can modify address and baud rate through registers, strong anti-interference ability for data transmission, load capacity ≤ 600 Ω, suitable for various PLCs or acquisition modules.
• Durable and sturdy, with flexible installation - all 304 stainless steel shell, protection level IP54, M18 × 1 thread with fixed nut or mounting bracket, overall size of Φ 18 × 113mm, standard 2-meter cable, can be quickly integrated into existing equipment.
• Low power consumption, easy to maintain - powered by 10-24V DC, with a maximum power consumption of only 1.2W. When the lens is stained, it can be cleaned with anhydrous alcohol and runs stably for a long time.
