These highly accurate flow-through sensors are suitable for experiments that require high precision in microfluidics. They can monitor low liquid flow rates through a unparalleled accuracy by using volumes down to 7.5 µL. There are 5 versions available for pressure ranges from 1 psi (70 mbar) to 100 psi (7 bar).
General
Five different High Precision Pressure Sensors are available depending on the pressure range you want to measure (from 70 to 7,000 mbar). This flow-through sensor is perfect for gases and liquids and can be easily plugged (inline) into your microfluidic setup with 3/32" ID tubing or 10-32 fittings for 1/16" OD tubing.
2 packages are available:
- The large package version (by default), for 3/32" ID soft-walled tubing.
- The small package version, for 1/16" OD rigid tubing. This version has been optimized to remove the dead volume. Having low internal volume, it is a perfect choice for many microfluidic applications.

Working Principle
It measures the pressure of fluid media flowing through and it works as gauge pressure sensor by measuring the positive and negative pressure relatively to the atmospheric one.
The MPS High Precision Pressure Sensor can work in digital mode and it needs to be connected to the specific Sensor Reader (click here for more information). The Sensor Reader is sold separately and can manage up to 4 different sensors at the same time. Thanks to the integrated software you will able to record, store and analyse the data gathered by the sensor directly on your computer.
Application
Create your complete microfluidic setup with the Microfluidic High Precision Pressure Sensor and the Sensor Reader. They are both compatible with several flow control instruments (syringe pump, peristaltic pump and pressure controllers). Our dedicated software and its user friendly interface allow you to control the data acquisition directly on your pc via USB. Place the inline sensor anywhere you want on your fluidic path and electrically connect the sensor to your Sensor Reader. This sensor does not modify the fluid flow in your system.
