This product is an online infrared temperature sensor that uses RS485 interface and supports Modbus RTU protocol. It adopts a high-sensitivity detection probe, with a measurement range covering -50 ℃~1200 ℃ (default 0-600 ℃), and an accuracy of ± 1% or ± 1.5 ℃ (whichever is higher) of the measured value. The optical resolution reaches 20:1, the spectral range is 8-14 μ m, and the emissivity is fixed at 0.95. The sensor has M18 × 1 thread, stainless steel housing, protection level IP54, supports 10-24V DC power supply, can be directly installed or used with a bracket, suitable for industrial non-contact temperature measurement scenarios.
