18.5 Contactless temperature measurement


emonstrating innovative market competence in the area of optical sensor technology, the new high performance Wenglor OptoTemp allows contactless temperature measurement within a range of -25 to 350º C based on infrared radiation emitted by the object, regardless of the material it is made of and state of aggregation.

The sensor measures temperature with a spectral sensitivity of 8 to 14 µm. The measured value appears at the integrated. Intuitively-operable display and is read out via the outputs of the RS 232 port. Due to its two switching outputs and an analog output, the sensor is suited for various measuring applications, for example target versus actual value comparison and absolute measurement. The integrated laser alignment tool and teachable emission factor make initial start-up quick and easy. This is a genuine allrounder with applications from conventional target versus actual value monitoring of liquids and raw masses, as well as process control for the prevention of temperature violations at nonmetallic surfaces, right up to the monitoring of engines and system components in the

automotive industry. Downtime is avoided, scrap can be reduced in production and uniform product quality can be assured throughout the entire value creation chain. Features: • Contactless temperature measurement within a range of -25 to 350º C • Two switching outs for simple setup versus actual value comparison • Freely scalable analogue output for absolute measurement • Output functions can be configured as desired (PNP/NPN, NO/NC, 4 – 20 mA / 0 – 10 V) • Emission factor adjustable from 0.1 to 1 • Integrated laser alignment tool • Easy adjustment via intuitive menu and 7 segment display or wTeach2 (RS 232) •

Laser distance sensor with new dual mode solves clear object detection and error-proofing applications


eaturing new firmware, the Q4X dual teach mode sensor combines window thresholds on both target distance and target reflected intensity, allowing the Q4X to reliably solve difficult applications with ease. The Q4X can now detect clear objects without requiring a retro-reflector. Dual mode can be used to error-proof applications by ensuring that the correct colour part is located at the correct position. Banner’s Q4X reliably detects distance changes as small as 1 mm and covers a 25 to 300 mm range. The sensor was already ideal for difficult distancebased sensing applications as it easily detects objects regardless of target surface reflectivity, including black foam on black plastic, black rubber in front of metal, multicolour packaging and targets of all colours. Now with the dual teach mode, the sensor can detect small changes in reflected intensity for targets inside the distance threshold. This powerful combination allows the Q4X to solve many new applications.

Incorporating the innovative dual teach mode into the next-generation Q4X sensor provides customers with a more powerful sensing solution for their most difficult applications. With combined intensity and distance thresholds, the Q4X extends its world class sensing performance to clear object detection and common error-proofing, or poka yoke, applications. Offering a simplified user experience, the Q4X includes a bright readout on a highly visible, angled four-digit display that is easily viewed from multiple vantage points. The Q4X also offers intuitive user setup utilizing three tactile push-buttons conveniently located below the display. The Q4X is constructed with robust housing rated to IP67, IP68 or IP69K, allowing use in wet and high-pressure washdown environments, durable FDA-grade stainless steel resists mechanical impact, over tightening, extreme vibration and aggressive cleaning procedures.
