New thermal imaging cameras of the Sonel KT series KT-400 / 385 / 200 / 195

A new series of thermal imagers / thermovision cameras offered by SONEL S.A. 

Thermovision cameras, as devices for temperature measurement, have found a wide application in industries such as construction, electrical engineering, medicine or other related activities. In the above-mentioned sectors, it is often impossible to make an easy, direct temperature measurement and even approaching the object (for example, making a temperature measurement by direct contact method using thermocouple). Difficulty to use the thermocouple also appears when a simultaneous, multi-point measurement of the surface temperature distribution is required. Such a multi-point the measurement is most easily performed using a sensing system with a sensitive multi 2D sensor for thermal radiation as it is  in thermal imaging cameras.

The operation of the thermal imaging camera is based on the measurement of radiation intensity of thermal energy, emitted by the measured object. Camera measurement system always consists of an optical system with lenses and 2D matrix of detectors sensitive to thermal radiation. The camera detector is built of many, small, individual detectors called pixels. The number of pixels in the camera affects a resolution and image quality. Lenses in such camera is made of transparent material for thermal radiation. The price of the lenses often is a results of the high cost of material used for production, for example a pure germanium crystal.

The process of image formation in the thermal camera is closely related to the optical system and a detector. Image, which we see on the camera screen, is formed by projecting radiation of object on the detector which passed through the lens system. The image is properly sharpened by lens adjustment through automatic function or by the camera operator manually before the recording process. Thermal image, also called a thermogram, which arises in the detector, is read by electronic circuits of the camera and saved in memory of the device. In the final stage of acquisition process the image can be displayed on the color screen of thermal camera as a photo or recorded as a movie or photo.

There are different types of thermal imaging cameras that differ by detector type. Each detector type has its own spectral sensitivity that determines the camera application. The are various spectral infrared ranges that the detector can cover. It can be a range of so-called close, medium or far-infrared. Mostly cameras with a sensitive detector cover a range of wavelengths from 8 up to 14 μm, i.e. the range of so-called far-infrared. This spectral range is mostly suitable for measurement of temperature distribution on the surface of various materials. These applies to in particular the construction and electrical industry or medicine, or wherever it is required to have qualitative and quantitative assessment during surface inspection of temperature distribution. Exactly this spectral range is used in KT cameras of SONEL S.A.

New KT series

A new series of cameras offered by SONEL S.A., which includes Sonel KT-400, Sonel KT-385, Snel KT-200 and Sonel KT-195 model are perfect for thermovision measurements. Those cameras are well suited for the construction and electrical industry, and at the places, where only non-contact measurement is possible in order to obtain information about the temperature distribution on the surface of the object. KT-400 camera, with high resolution and a detector with 384 x 288 pixels, allows obtaining a high quality image from a close distance of 0.5 m, as well as from a long distance. Its field of view is 28.4 ° x 21.5 ° with the standard lens. The camera has high sensitivity in full temperature measurement range from -20 ° C up to + 650 ° C with the possibility of extending the range up to 1500 ° C by changing the lens. The measurement result can be analyzed directly in the camera or after sending data to the computer using the ThermoAnalyze2 program. This module allows you to both create and print reports directly from the device, and has built-in communication interfaces (WiFi, Bluetooth, Mini HDMI, microSD) which ensures communication between the camera and the computer or a mobile device.

Full control and flexibility

Regardless of whether you take pictures or record movies the  latest cameras from SONEL S.A. equipped with modern  matrices, wide range of temperature measurement and high quality lenses, guarantee high level of details of registered images and accuracy . Cameras come in several variants, allowing for proper selection configuration for individual requirements users. More to watch, less to hold.

Large, 4 "display with innovative electronics that processes the data has been placed in a compact housing, which ensures perfect balance between high performance and a small size is ideal for everyday work. In addition, thanks to centrally placed navigation button on the menu on the touch screen support simple and intuitive operation. Thermovision is not everything. Cameras additionally are equipped with a visible image lens and related "mixing" technologies for images: PIP and MFI. Built-in LED flashlights and laser improve the quality of work making it easier to take pictures as well as interpretation of the collected images. Picture it It's just the begining. Thanks to the latest technologies and solutions KT cameras from SONEL S.A provide full control and flexibility in various situations, being an ideal tool, both for novice users and professional thermographers.
