Product Details Supplier Info More products

Sensirion has introduced the LG01 micro flow switch for ultra-low liquid flow rates and bubble detection in bio-medical and process control applications.

The sensor is said to make fluidic systems more reliable by enabling the detection of liquid flow within the range of a few millilitres per minute and less.

For such measurements, the sensor offers a response time of less than 100ms.

Its output signal of either 0V or 5V indicates whether the current flow rate is above or below the specified flow switch level.

At continuous flow rates above this limit, the identification of air bubbles within the flow channel is equally consistent.

Maximum flow rates are accepted up to 220ml/min.

Fluidic connections can be made via 1/4-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8in (3.2mm) or 1/6in (1.6mm).

Barb connector adapters are available as an alternative.

The small and light sensor is designed for integration into bio-medical applications and general process control solutions.

Good chemical resistance and biocompatibility are ensured by its non-invasive measurement through the wall of the straight, internal glass capillary (diameter 1.8mm) and fluidic connectors made of PEEK high-end plastics.

The product is based on a digital MEMS chip.
