Introtek now offers custom-designed, noninvasive, ultrasonic, point level sensors for use with soft bodied PVC drip chambers, which are common in many patient-connected medical device applications.

Introtek now offers custom-designed, noninvasive, ultrasonic, point level sensors for use with soft bodied PVC drip chambers, which are common in many patient-connected medical device applications.

This sensor design provides excellent acoustic coupling without the need for any type of coupling agent and without allowing the drip chamber to become "relaxed" in the sensor, thus helping to eliminate false air alarms.

It offers a simple one-piece construction without any handles, springs, doors or clips inherently found on other existing drip chamber level sensors.

Anyone who has an application for air bubble, air-in-line or liquid level detection can send a sample drip chamber (or tubing) to Introtek.

The company will evaluate it and provide the optimum prototype sensor manufactured to form, fit and functional requirements.

Features include: simple one-piece sensor construction for various diameters and tapers; no moving parts - unibody construction; noninvasive pulse-type ultrasonic technology; panel mount or self-standing versions; positive locking effect for drip chamber; design resists effects of vibration or drip chamber slippage; no coupling agent is necessary; design allows for constant visual confirmation of fluid level; operates with microcontroller based integral electronics; alternative electronics options available; and high noise immunity to EMI/RFI.
