Product Summary

Unique CMOSens

planar packaging technology

enables non-invasive measurement of liquid flow

inside a cost-effective planar form factor. The flow

channel passes through the planar substrate and is

connected to fluidic channels via a manifold. The fluid

is only in contact with the glass channel. The digital

microsensor chip provides the full signal processing

functionality for a fully calibrated, temperature-

compensated digital output.

Integration of the LPG10-1000 Liquid Flow Sensor

Due to the dramatically reduced size and downmount fluidic connections, the LPG10-1000 allows an outstandingly

compact mechanical, fluidic, and electronic integration. To receive support and acceleration on initial testing, please

contact Sensirion about existing integration solutions.

Digital Communication via I²C-Bus

The electrical connection to the LPG10-1000 flow

sensor is illustrated in the schematic drawing shown

in section 3.2.

3.2

Sample Circuitry

Digital

communication between a master and the

LPG10-1000

sensor runs via the standard I²C-interface.

The physical interface consists of two bus lines, a data

line (SDA) and a clock line (SCL) which need to be

connected via pull-up resistors to the bus voltage of the

system. By default, the I

C address is set to 64

(hexadecimal: 40, binary: 1000000).

These lines can be used on a 3.3 V level with a clock

frequency of 100 kHz. For the detailed specifications of

this I²C communication, please refer to specific I²C

Attention fragile!

Mechanical shocks and touching or probing of the glass surface may lead to stress on the chip and

may damage the glass package.



The thin-walled top layer can easily break. Thus, do not touch the planar glass package on

the top surface with your fingers or tools (e.g. tweezers).



Respect the burst pressure specification. Be aware that injecting fluid by hand with a

syringe can lead to large pressure peaks.



Do not exert pressure on the sensor chip. Mechanical structures must not be in contact

with the sensor chip (see bounding box above).



Do not operate the liquid flow sensor when the contact pads have been wetted. Dry first.

Ordering Information

Standard shipment includes only the sensor, neither cables nor fluidic connection material.

For easy testing, an Evaluation Kit is available. The kit contains:

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. When using the Evaluation Kit, the wetted materials include PMMA

(manifold) and FKM (O-Rings), as well as borosilicate glass (LPG10 sensor).

For integration support, please see the Application Note “Engineering Guidelines for LPG10 Integration”.

The connector cap included in the Evaluation Kit can be purchased in combination with the LPG10-1000 sensor.

Contact Sensirion for more information on the Evaluation or the Connectivity Kit.
