Infrared thermometer determines response time
The response time indicates the response speed of the infrared thermometer to the change of the measured temperature, which is defined as the time required to reach 95% of the energy of the final reading. It is related to the time constant of the photodetector, the signal processing circuit and the display system. Some infrared thermometers have a response time of up to 1ms, which is much faster than contact temperature measurement methods. If the moving speed of the target is very fast or when measuring a rapidly heated target, a fast-response infrared thermometer should be used, otherwise the sufficient signal response will not be achieved, which will reduce the measurement accuracy. However, not all applications require fast response infrared thermometers. For stationary or thermal inertia of the target thermal process, the response time of the thermometer can be relaxed. Therefore, the selection of the response time of the infrared thermometer should be adapted to the situation of the measured target. The response time is determined mainly according to the movement speed of the target and the temperature change speed of the target. For stationary targets or target parameters in thermal inertia, or the speed of existing control equipment is limited, the response time of the thermometer can be relaxed.
