Introtek has produced non-invasive ultrasonic air bubble detectors, continuous liquid level sensors, optical blood component detectors, and now pressure occlusion detectors for thousands of companies in dozens of industries including medical device manufacturers, chemical processing, pharmaceutical development, clinical laboratories, and food & beverage manufacturers. Introtek sensors utilize a patented pulse-type ultrasonic technology that detects air bubbles, air-in-line, and liquid levels with the highest degree of accuracy and reliability, thereby maintaining an extremely high MTBF. Additionally, Introtek sensors are not susceptible to the limitations exhibited by continuous wave, capacitive, or load-cell sensors.
