Sensirion LPG10-1000 Digital Planar Liquid Flow Sensor

Sensirion LPG10-1000 Digital Planar Liquid Flow Sensor provides high performance and speed in measuring liquid flow in a planar microfluidic glass substrate with down-mount fluidic ports for highly compact integration into any fluidic manifold system. Measuring 10mm x 10mm x 2.35mm³, the LPG10-1000 is ideal for high-volume applications with strict space limitations. Microfluidics chips and digital microsensor chips are combined to measure liquid flow inside a planar glass substrate. The digital microsensor chip provides full signal processing functionality for a fully calibrated, temperature compensated, linearized digital output.

The LPG10-1000 is a smart sensor solution offering flow rates from the low microliter per minute to 1ml/min. Glass, the wetted material, ensures optimum compatibility with biological and pharmaceutical processes. Due to the small thermal mass, response times below 30ms can be reached. The Sensirion LPG10-1000 Digital Planar Liquid Flow Sensor also offers real-time detection of failures such as clogging, air bubbles, or leaks.

Development Tools

Sensirion LPG10-1000 Evaluation Kit

Evaluation kit for testing the LPG10-1000 Digital Planar Liquid Flow Sensors.

Sensirion LPG10-1000 Evaluation Kit includes one LPG10-1000 sensor, preassembled in a fluidic manifold (PMMA), featuring ¼-28 flat bottom fluidic fittings. The fluidic seal between sensor and manifold is ensured using two O-Rings (FKM). The included connector cap secures the sensor to the manifold and features a 4-pin Molex connector. The included Molex adapter cable, USB cable, and software allow for easy evaluation using a PC.
