Compact temperature measurement devices

The WIKA Group is celebrating the manufacture of 1 million MH-4 mobile hydraulic pressure sen- sors since it launched the product just one year ago in 2020. The MH-4 is a powerful, reliable and highly re- silient pressure sensor. Because the challenges in practice are high, for safe machine operation, the sensor must deliver high-precision measured data, even under the most demanding conditions. With constant performance stability during the full life cycle, the MH-4 ensures the greatest possible operational safety. Instrotech has available the Optris temperature measurement devices, Xi 80 and Xi 400, which combine the benefits of infrared cameras and infrared thermometers. “With the Xi series, we are launching a semi-autonomous sensor which, in addition to traditional PC- and software-based operation, also works as a smart pyrometer with analogue or digital outputs, and seeks the target on its own. This opens up new fields of application, in mechanical engineering for example, or for multi-sensor applications,” says Torsten Czech, Head of Product Management at Optris. Ideal for OEM applications The Xi series is a fusion between a robust, compact py- rometer and an advanced IR camera. The integrated au- tomatic spot finder function enables accurate tempera- ture measurements in moving objects without the sensor having to be readjusted. Sensor adjustment takes place autonomously, without needing a connection to a PC. In addition to a direct 0/4-20 mA analogue output, the de- vices also offer users digital interfaces such as Ethernet or RS485. An external processing interface provides for the further processing of up to nine freely definable ana- logue outputs. This makes the pyrometer ideal for OEM applications. Motorised focus, easy installation and use Both Xi models are equipped with a motorised focus which enables remote focusing using the free PIX Connect software. The sensors have a resolution of up to 382 x 288 pixels, a frame rate of up to 80 Hz and a measuring spot to distance ratio of up to 390:1. Xi devices are calibrated for temperature measurements within a range from -20 to 900°C. Customers receive a ready-to-use package including a mounting nut, a mounting bracket, software and a connection cable. Microscope optics The new microscope optics for the Xi 400 infrared cam- era provide for reliable temperature measurement on 1 000 000 MH-4 sensors since launch in 2020

The microscope optics of the Optris Xi 400 provide for temperature measurement on tiny objects.

tiny objects from 240 µm. In combination with a suitable stand, this enables professional measurement of printed circuit boards and other electronics components. The measuring distance between camera and object is var- iable between 90 and 110 mm. The built-in motor focus allows for an easy focusing of the camera with the includ- ed PIX Connect software. Key specifications - Analysis of smallest components down to 240 µm - Motorised focus provides for easy handling Applications Circuit boards are a core part of electronic devices. They keep getting smaller – and more powerful at the same time. Temperatures of assembled circuit boards can eas- ily be measured with the microscope optics of the Xi 400 thermal imager so overheated areas can be identified quickly. The causes for excessive temperatures can be many: defective components, incorrectly dimensioned circuit paths or poorly soldered joints. When these are detected in production, they can be prevented. - Recording of radiometric videos - Optical resolution: 382 x 288 px.
