0-1000 ℃ Industrial Online Non-contact Infrared Temperature Controller Thermometer Sensor 4-20mA Temperature controller power supply: AC 220V, if you need AC 110V, pls add $15 USD. Wiring instructions: The red is connected to instrument terminal 5 (24V+), the blue is connected to instrument terminal 3 (4-20ma+), and the black & orange is connected to instrument terminal 1 (GND) Specification: The infrared temperature sensor calculates the temperature of the surface of the object by measuring the intensity of the infrared radiation emitted by the target without contacting the target. Non-contact temperature measurement is the biggest advantage of infrared thermometers. Users can easily measure the target temperature that is inconvenient to approach or move. Temperature Controller Power Supply: AC 220V Features: Protection level: IP65 (NEMA-4) Ambient temperature: 0~60 ℃ Storage temperature: -20~80 ℃ DC power supply (default) 24V DC For Temperature Sensor Maximum power consumption: 1.2W Accuracy (default) +-1% of the measured value, whichever is greater Transmitter circuit working environment: temperature 0-60C relative humidity 10-95% (non-condensing) Measuring temperature: 0-1000℃ Spectral range: 8-14um Optical resolution: 20:1 Response time: 150ms (95%) Emissivity: 95% fixed Output signal: 4-20MA Load capacity: <=600 ohm What in Package: 1 X Temperature display unit 1 X Infrared temperature sensor
