(Relay needed.) Please note that in case touching with bare hand, it might be burnt or frostbitten. The Thermal Image IR sensor checks every 2 seconds the 768, 4800 or 9600 sensor points to see if all measure- They are usually thermistor devices. Negative Temperature Coefficient (NTC) thermistor A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. It can be glued or cemented to a surface and its temperature will be within about 0.01˚C of the surface temperature. Our Thermal Sensors feature the same field of view (FOV) at a maximum sensitivity of 50% as general sensors. Key topics include sensor materials, CMOS-compatible sensors, measurement capabilities, thermal management and manufacturing processes. Potential applications include motor overload and semiconductor protection, electronic assembly thermal management and temperature compensation, as well as HVAC/R equipment. 4 MEMS Thermal Sensors D6T Safety Precautions Precautions for Correct Use Installation † The Sensor may not achieve the characteristics given in this data-sheet due to the ambient environment or installation location.
