Cosense, a designer and manufacturer of ultrasonic air bubble detectors and liquid level sensors, has developed a new SL-630 series, a compact, non-invasive, self-adhering point liquid level sensor for use with various fluid reservoirs, reagent containers and bottles.

The SL630’s sensor is positioned on a container using its adhesive interface or a mechanical fixture. Circuitry is located integrally with the sensor housing, which measures 12.7mm by 22.9mm. Sensors operate with 5VDC–24VDC input and TTL or open collector output options, indicating air or liquid is present.

Designed for use with medical and biotech instrumentation, SL630 sensors are not affected by optical or dielectric properties of fluids or containers. Standard and custom designs are available for OEM applications.
