Can I trust the temperature measurement of a single pixel?

Due to the diffraction-limited nature of infrared optics, the optical resolution and image quality are physically limited. As the dimensions of the individual pixels are in the same range as the infrared wavelength, users shall ensure that the target is larger than the camera’s MFOV.

Can I use the Xi400 LT USB thermal camera with Ethernet?

The Xi400 is a USB infrared camera. For an Ethernet infrared camera, please review the Xi410 or use a W&T USB-to-Ethernet redirector.

What is the speed of the Xi400 thermal camera?

80Hz

Where is the Xi 400 LT USB made, and does it contain memory components sourced from outside the U.S. or the European Union?

The Xi 400 LT USB thermal camera is designed, manufactured, and calibrated in Berlin, Germany. Some electronic components may be sourced from outside the EU or the US. Still, it is important to note that the Xi 400 LT USB does not store any thermal images or temperature values in non-volatile memory. The Xi 400 LT USB thermal camera only stores full thermal images, thermal video (.ravi files), and temperature values in the customer PC hosting the PIX Connect software necessary to operate the camera. The thermal camera uses memory components inside the camera electronics, which may be sourced outside the EU or the US, to store a reference picture (also called dark picture) of the non-uniformity correction paddle or flag and some reference temperatures used to correct temperature drift. All these memory elements are deleted when the power to the camera head is terminated.

Does the Xi 400 LT USB thermal camera have any Wi-Fi or other communication capabilities?

The Xi 400 LT USB thermal camera has no electronic components that enable external communication.

Can the Xi 400 LT USB thermal camera operate without a connection to a computer?

The Xi 400 LT USB thermal camera must be connected to a PC loaded with Optris PIX Connect software to produce thermal images and remote temperature measurements. By eliminating processing in the thermal camera head and leveraging PC processing power, the thermal camera head size can be reduced, and the ambient operating temperature can be increased. Autonomous operation (without the use of a PC) is supported in other Optris Xi-series infrared cameras, such as the Xi410 LT ETH.

Can the Xi 400 LT USB thermal camera send temperature information from spots or areas to my PLC?

The Xi 400 LT USB thermal camera can send temperature information or temperature alarms from the Process Interface connection on the back of the thermal camera. A cable with integrated electronics and a terminal block is included with the thermal camera. It can be programmed in PIX Connect software as an Analog Input (AI) and Digital Input (DI) to control the thermal camera or as an Analog Output (AO) to control the process. The signal level is always 0-10 V (DI = 24 V). An optional industrial process interface is also available, delivering up to three independent temperature values or alarms to a user-supplied PLC. USB-RS485 adapters are available for applications with output requirements for more than three areas.

Example:

What is the bit depth of our camera?

The bit depth of our cameras is 14 bit. The data has 16 bit but only 14 bit are used for the Temperature Data and the other 2 bits are not used

Can we send the raw ADU data from the camera to another commercial software for processing?

As a rule, we do not disclose any information about raw data. The only option is to use the Connect SDK to output the camera’s ADU values as a matrix. However, these ADU values are uninterpreted. The cameras can send the temperature information and the color information to another commercial software for processing.

Does changing the mode from Temperature to ADU in the Connect SDK change the way that the image is displayed?

No , the way the image is displayed does not change. You can see this in the software examples provided with the PIXConnect software (See the menu HELP => Connect SDK => Examples). Under the configuration menu => External communication => ConnectSDK you can change the mode from “Temperatures” to “ADU”. This has no influence on the displayed image.

Our company designs and supplies camera systems for steelmaking processes and is exploring different camera types. For this application, would you recommend long-range, near-infrared, or short-wave infrared models?

For steelmaking processes we recommend short-wave infrared cameras as the PI 1M camera, PI 08M camera, PI05M camera , Xi1M camera or Xi 05M camera. Use the lowest wavelength / spectral range as possible!

Which Optris infrared cameras support integration with machine learning frameworks? Do they provide raw thermal image data access via SDK/API (e.g., the OTC SDK), allowing developers to apply custom ML models for tasks like segmentation, classification, or predictive thermal analysis?

The IR cameras do not provide any raw thermal image data access. You get the temperature data via the SDK (OTC SDK) from the camera to your process.

Which Optris infrared camera is best for measuring temperatures during welding processes?

– The choose of the correct Optris infrared camera depends on the temperature range and the type of the welding process.
– For plastic welding , a PI/Xi LT camera can be used (8-14 µm)
– For metal (e.g. steel applications) a short wavelength camera PI 1M/08M/05M , Xi 1M , Xi05M should
be used (0.85-1.1 µm , 780-820 µm , 500-540 µm)
– For laser welding applications Optris provides IR cameras with a blocking filter.
