LD20 Datasheet, PDF (1/6 Pages) List of Unclassifed Manufacturers – Low flow sensing up to 1200 ml/h (20 ml/min)

LD20 Liquid Flow Sensor Series – PROTOTYPE
Single-Use Flow Sensor for Biomedical Applications
 Low flow sensing up to 1200 ml/h (20 ml/min)
 Luer lock or barbed fluidic connectors
 Millisecond-fast response time
Product Summary
The LD20 liquid flow sensor series enables precise and
reliable measurements of dynamic liquid flow rates
from a few hundred µl/h up to 1200 ml/h bi-
directionally. This sensor has been designed for single-
use applications in the biomedical field. The LD20
series is still being developed. Thus any specification
can be subject to change in the future (performance,
fittings, communication, etc.).
Electrical Interface:
Digital
- I²C-Bus
For more information on communication, please refer
to section 3 of this document (preliminary).
1 Sensor Performance (Preliminary data, subject to change)
The following Table 1 lists preliminary specifications of the current prototypes. Please contact Sensirion if different
specifications are required.
3D-printed samples of the small (LD20-0600) and medium (LD20-1300) LD20 versions are available on request.
Please contact Sensirion.
