Drip Chamber Ultrasonic Liquid Level Sensors
INTROTEK® Non-Invasive Drip Chamber Level Sensors are custom designed for use with soft-bodied drip chamber or larger OD tubing to overcome conditions such as relaxation, slippage or vibration, which would normally cause false air alarms. Each sensor is custom designed for the specific drip chamber and is available with single and multipoint detection. These sensors are designed to meet OEM form, fit and functional specifications for various diameters and tapers.

Product Details
Introtek’s pulse-type ultrasonic technology provides highly reliable, non-invasive air bubble detection capabilities in the most critical applications where the safety of a patient or process is mandatory. Many of the variables, which can affect performance of amplitude or continuous wave based sensing systems, are eliminated or greatly reduced, thus yielding accurate and repeatable detection.
Applications
- Air bubble, air-in-line and liquid level sensing.
- Patient-connected medical devices, including: • Apheresis • Heart-lung bypass • Auto-transfusion • Dialysis • Infusion pumps • Cardiac assist pumps • Perfusion-based “life support” devices.
- Immunoassay and diagnostic equipment.
- Liquid and chemical dispensing.
- Blood processing equipment.
Technology
- Integrated Electronics.
- Accurately outputs optical pulse for each drop during IV infusion.
Safe
- High noise immunity to EMI / RFI
- Highly reliable.
