Microfluidic In-Line Pressure Sensor

  • New release


The PRESSURE UNIT is a stand-alone microfluidic in-line pressure sensor for continuous  measurement of  pressure in a fluidic path. The product line can detect values over the range of -1000 mbar (-15 psi) to 7000 mbar (100 psi). The sensor can be directly connected to a PC via USB, and can display measurements in real time on the Fluigent OxyGEN software interface. Users can output  values for custom software applications using the Software Development Kit.

With our microfluidic in-line pressure sensor, you can accurately monitor and control pressure in a stable, pulseless and responsive manner.

Three different High Precision Pressure Sensors are available (S, M, and XL) depending on the pressure range you want to measure. This microfluidic in-line pressure sensor is perfect for gases and liquids and can be easily plugged (inline) into your microfluidic setup with 1/16" OD tubing.

Pressure Unit: an in-line Pressure Sensor Features aWide Range of Detection

Wide range of detection

The PRESSURE UNIT is a microfluidic in-line pressure sensor that allows the accurate measurement of pressure and vacuum within the range -1000 mbar to 7 bar. Our in-line pressure sensor disposes of a wide range of reading flow rates.

Display in real-time

Graphically monitor the pressure measurement using Fluigent’s  OxyGEN software. Our dedicated software and its allows users to control the data acquisition directly on a pc

No hub is needed

Directly plug the sensor to aPC and benefit from a compact solution for pressure detection. The microfluidic in-line pressure sensor can be plugged anywhere (inline) in your microfluidic setup.

Pressure Control

Users can achieve precise pressure control by combining any microfluidic in-line pressure sensor with our pressure controller system.
