Micro Flow Switch and Bubble Detector

By Design Engineering Staff   


Sensirion LG01 flow switch designed for bio-medical and general process control.

The Swiss sensor manufacturer Sensirion AG is launching the LG01 micro flow switch for ultra-low liquid flow rates and bubble detection. The sensor offers a response time below 100 ms and its output signal of either 0 or 5 volts indicates whether the current flow rate is above or below the specified flow switch level. Maximum flow rates are accepted up to 220 ml/min.

Fluidic connections can be made via 1⁄4-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8-inch (3.2 mm) or 1/6-inch (1.6 mm). Barb connector adapters are available as an alternative.
