Optris introduces a series of innovations and product upgradings in its infrared thermometer series in the compact class of online sensors.

The new accessory kit CTex is a technology leap for applications in hazardous and explosion-prone environment: This kit is a cost-effective solution for miniaturized infrared sensors to be used in explosion-risk area. This preassembled set is to be installed between the CT sensing head and its electronics. The intrinsic safety according to ATEX-, FM- and CSA-standards is guaranteed by double zener barriers, which restrict the power input into the sensing head.

A further innovation is the CTmatrix - a low-cost alternative for the use of line scanners and thermo cameras in automation solutions. On the basis of the CT-series the engineers designed an infrared multiple sensor array with software. It consists of either 9 or 25 sensors. The infrared sensing heads can be arranged as a two-dimensional matrix or in a single line.
The CTmatrix can be used in various manufacturing processes, like thermoforming processes. Sensors - arranged in a field of 5 x 5 - support the temperature measurement during the heating process of the material and enable regulation and control.

The sensors are installed between the heating elements. Due to their resistance to high temperatures the sensors do not need any cooling up to 180°C. As they can measure through narrow sighting tubes, they also do not need complicated air flushing to keep the lens clean. The sensors are interconnected via a RS485 two-wire interface. The electrical connection is provided straightforwardly by power supply and two additional cables.

The software CTarray displays the temperature of the material of each heating section. The arrangement of the sensors depends on the application: A single line matrix (bended) may be suitable to measure temperatures in drying facilities for varnish and paint etc.
