The Coronavirus Pandemic leads to an increased need Measurement Technologywith which the body temperature can be determined quickly and reliably. Optris presents a new IR camera for measuring fever. With the PI 450i, software-supported based on the Infrared measurement technology Measure the surface temperature of a person's face even in passing.

Checking each person individually for their body temperature is too cumbersome and time-consuming in times of the coronavirus pandemic. The current version of the Infrared camera PI 450i has an optical resolution of 382 x 288 pixels. The scope of delivery includes the PIX Connect software. IR camera and software detect the surface temperature on people's faces.

There are two configurations: The first measures the temperatures of people in a crowd. With the second solution, people can be checked individually for an elevated temperature. The second measurement provides more reliable results because the contactless one Temperature measurement in the corner of the eyelid takes place at which the temperature has the strongest correlation to the core body temperature. Optris offers the right optics for both variants so that measurements can be carried out at an optimal distance.

Reference radiant heater for high absolute accuracy

The infrared thermal imaging camera PI 450i has a thermal sensitivity of 40 mK. The absolute accuracy of temperature measurement for infrared cameras is typically ±2 °C. For even more precise measurements, the PI 450i can be combined with a reference source. The BR 20AR spotlight has a high-precision internal temperature sensor.

The PIX Connect software processes this reference signal. This results in an overall accuracy of the thermal imaging camera system of ± 0,5 ° C. The software runs on any standard PC and can be commissioned and configured quickly and easily. For example Temperature thresholds can be defined which, if exceeded, automatically trigger an alarm.

The new infrared camera for fever measurement can be used wherever a contactless checking is necessary for many people to have elevated body temperatures to prevent the virus from spreading further. Possible locations for the thermal imaging cameras are airports, train stations, hospitals, schools, offices, shopping centers, etc.
