The Sitrans Probe LU240 (photo) is this company’s newest ultrasonic level-measurement HART transmitter. Field-proven echo processing separates true material-level echoes from false, providing reliable readings while still allowing rapid response to actual changes in the material level. The device’s reduced blanking distance decreases waste in applications while boosting asset utilization by providing continuously accurate readings, even with high levels of material. For those applications requiring process temperature data, the Sitrans Probe LU240 now provides users both level and temperature readings. In dirty applications or those with buildup, the transmitter’s maintenance-free active-face technology keeps the sensor clean and is also unaffected by wind, rain, snow or temperature changes. For rugged applications in harsh environments, it is IP68 fully potted and encapsulated with a polyvinylidene difluoride (PVDF) sensor that is resistant to corrosion, chemicals and extreme shock. — Siemens AG, Munich, Germany
