No. It senses through the wall of transparent tubing, reducing the risk of fluid-circuit contamination and additional flow resistance.
FOREACH ABD Air Bubble Detection Module for identifying bubbles, droplets and gas/liquid states in transparent tubing, available in configurations for transparent flexible tubing with outer diameters of 1.6–6.4 mm
The ABD air bubble detector detects bubbles, droplets and gas/liquid states in transparent tubing. It uses non-contact infrared sensing to distinguish gas from liquid by their different optical responses. The sensor does not contact the fluid, avoiding additional contamination and flow resistance.
Designed for fluid-line monitoring in IVD, life science, laboratory automation, environmental monitoring and food testing equipment, ABD supports bubble alarms, droplet detection, reagent-line status monitoring and equipment fault protection. Configurations cover common transparent tubing ODs from 1.6 mm to 6.4 mm; choose the configuration to match the actual tubing OD.
Typical Applications:
Bubble alarms, Droplet detection, Transparent tubing status monitoring, Reagent-line status detection, Fluid-circuit fault protection, Tubing monitoring in automated instruments
