Use Inline Pressure Sensors to Monitor Pressure in Real Time and Support Stable, Repeatable Fluidic Performance
Real-time pressure sensing gives you practical insight into how a fluidic system behaves during operation. By using inline pressure sensors at key points in the flow path, you can track changing pressure conditions, detect early signs of blockages, and mitigate risks that could compromise important samples. This kind of visibility supports consistent operation, helps you pinpoint issues before they escalate, and provides a stronger foundation for developing, refining, and maintaining reliable fluidic systems.
Why Real-Time Pressure Monitoring Matters in Fluidic Systems
In fluidic systems, pressure is one of the earliest indicators that something in the flow path is changing. Even small shifts can signal developing blockages, flow instability, or conditions that may affect sample integrity or overall system reliability. Real-time pressure monitoring helps you see these changes as they occur, so you can respond more quickly and keep your process running smoothly.
What pressure monitoring can reveal about system behavior:
- Developing blockages in the flow path
- Early signs of flow instability
- Pressure spikes or drops that indicate changing system conditions
- Situations that may compromise sample integrity
- Unexpected resistance or restrictions within the fluidic pathway
- Shifts that signal the need for maintenance or adjustment
Real-time visibility makes these changes easier to catch before they interrupt your fluidic system. Instead of discovering issues after pressure has already changed or a sample run has been affected, continuous monitoring gives you immediate feedback about how the system is behaving. This helps you make quicker adjustments, maintain stable operation, and keep your fluidic process on track.

How Inline Pressure Sensors Work
Inline pressure sensors measure pressure changes within a fluidic pathway. A fully isolated Micro-Electro-Mechanical Systems (MEMS) sensing element reacts instantly to physical pressure changes in the fluid transmitted through a gel-filled cavity, allowing pressure to be monitored in real time. Onboard electronics provide signal conditioning, analog-to-digital conversion, and I2C communication, enabling pressure data to be integrated directly into system monitoring and diagnostics.
Key elements of the PS200 sensor design include:
- Fully isolated MEMS sensing element
- Gel-filled transmission cavity
- Low internal volume for sensitive fluidic applications
- Onboard signal conditioning, analog-to-digital conversion, and I2C communication
- Real-time monitoring up to 200 psi (13 bar)
How Real-Time Pressure Monitoring Supports Reliable Fluidic Operation
Real-time pressure monitoring plays a critical role in maintaining stable, reliable fluidic operation. By providing continuous visibility into pressure conditions during use, inline pressure sensors help systems respond more effectively to change, reduce the risk of disruption, and support consistent performance across a range of operating conditions. The following capabilities highlight how real-time pressure sensing contributes to reliable fluidic operation at the system level.
High Precision With Continuous Monitoring
Fast response time and stable signal (low drift) performance help maintain predictable operation and make it easier to identify pressure shifts early, before they affect your process. The PS200 can also easily communicate with the I2C (Inter-Integrated Circuit).
Optimize System Reliability
The sensor’s low internal volume, negligible backpressure, and fully isolated MEMS element enable precise pressure measurement. This makes the PS200 well-suited for sensitive or tightly controlled fluidic pathways.
Consistent Operation Across Diverse Fluids
The sensor is compatible with a range of life science reagents in a small form factor. It is compatible with ¼-28 fittings and manifold-mounted configurations. This flexibility allows it to integrate into a broad range of fluidic designs.

How Inline Pressure Sensors Fit into Your Fluidic Design
Inline pressure sensors can be incorporated into fluidic systems in different configurations, depending on how you route fluids, where you need visibility, and how your components are arranged. The PS200 supports both stand-alone and manifold-mounted configurations, allowing it to be placed at key points in the flow path without disrupting operation. This flexibility makes it easier to integrate real-time pressure monitoring into a wide range of fluidic designs.
Stand-Alone Sensors
Stand-alone sensors integrate into a fluidic pathway using standard ¼-28 fittings, making it easy to place them at key points in your system. This configuration is ideal when pressure monitoring is required without altering an existing manifold design or when you need more flexibility for sensor placement.
Manifold-Mounted Sensors
For more compact or integrated builds, you can mount a sensor directly onto a manifold. This configuration supports tight space requirements and cleaner routing, and streamlines your fluidic system.
