1Surface temperature of the object can be calculated by measuring intensity of infrared radiation emitted by the target without touching the target. 2An optical lens is used inside to receive the infrared dispersion from the object. And the measurement is accurate, while the response speed is fast, the life is long and the operation is simple and convenient. 3Infrared technology of infrared temperature sensor and its principle are undoubtedly understood as its accurate temperature measurement passively accepts infrared amplitude dispersion of objects, compared with other temperature measurement products to achieve repeatability 4This Infrared thermometer probe is an integrated infrared thermometer, which is small in size and easy to install. The stainless steel shell can better resist electromagnetic interference and other characteristics. 5Such temperature sensor probe is suitable for food processing, steel smelting, chemical equipment, maintenance and repair, substations, industrial equipment, and it can also be used to measure the temperature of moving, live and inaccessible objects.Item Type: Temperature sensor probe DC Power Supply: 12V-24V DC Output Signal: 4-20mA Sensitivity: 1% Fs or 1.5 (take the maximum value) For Spectral Range: 8-14um Temperature Range: 0-100 / 0-200 / 0-300 / 0-400 / 0-500 / 0-600 (optional) Response Time: 300ms (95%) Optical Resolution: 12: 1 Emissivity: 0.95 fixed Probe Size: Approx. 115 x 18mm / 4.53 x 0.71in(Length x Diameter) Material: Stainless steel Power Consumption:1 x Temperature Sensor Probe
