Differential Pressure Sensors: Precise and Compliant Monitoring of Controlled Environments
In environments with stringent cleanliness and safety requirements – such as cleanrooms, pharmaceutical laboratories or sterile production areas – differential pressure measurement is a critical parameter. It enables air circulation between different areas to be controlled and the risk of cross-contamination to be prevented. To meet these challenges, Dickson offers a range of high-precision differential pressure sensors, perfectly integrated with its OCEAView monitoring solution.
Single Differential Pressure Smart-Sensor
Single differential pressure Smart-Sensor (-500 Pa to +500 Pa), it measures the difference in pressure between two zones, such as a high-pressure cleanroom and “regular” room or hallway.
Dual Differential Pressure Smart-Sensor
Dual differential pressure Smart-Sensor (-500 Pa to +500 Pa), it measures the pressure difference cascading between several different pressure zones, such as a cleanroom and a “regular” room or hallway.
Single Differential Pressure Smart-Sensor Connector
Single differential pressure Smart-Sensor + connector (-500 Pa to +500 Pa), it measures the difference in pressure between two zones, such as a high-pressure cleanroom and “regular” room or hallway. It also features a Binder connector to connect another sensor.

Differential pressure sensors designed for precision, reliability and integration
Dickson differential pressure sensors are designed to measure pressure differences between two adjacent zones with extreme reliability. Whether maintaining a positive pressure in a cleanroom or controlling a negative pressure zone in a confined environment, these sensors ensure :
- Optimum measurement accuracy, even in very low pressure ranges, thanks to intelligent sensor technology and the rigour of our Cofrac ISO/IEC 17025-accredited calibration laboratory.
- Seamless integration within the OCEAView ecosystem, enabling data to be centralized, displayed in real time and analyzed for trends.
- Simple installation with compact modules, flexible mounting options, and connectivity to suit different contexts thanks to compatibility with our Cobalt range of data loggers.
These sensors are ideal for pharmaceutical establishments, hospitals, research laboratories or any installation requiring rigorous control of airflow.
The challenges of differential pressure measurement
Differential pressure is much more than just an environmental indicator: it is an invisible safety barrier. In many regulated sectors, it is used to :
- Ensure the direction of air flows and prevent contaminants from circulating between two controlled cleanliness zones.
- Maintain compliance with regulatory standards such as ISO 14644, FDA 21 CFR Part 11, GxP, etc.
- Immediately detect any operating anomaly: a drop in pressure between two zones may reveal a problem with ventilation, a filter or an uncontrolled opening.
Continuous measurement of differential pressure, combined with defined alert thresholds, enables rapid intervention to correct any deviation and avoid non-compliance or critical product loss.
A complete solution with OCEAView: performance, simplicity, compliance
In addition to the sensors themselves, Dickson offers a complete environmental monitoring solution with OCEAView. This monitoring platform centralises, displays, secures and exploits data from all Dickson data loggers and probes. Its main benefits include :
- Real-time alerts: if thresholds are exceeded, users receive immediate notifications (SMS, e-mail, visual alarms) so they can react without delay.
- Guaranteed regulatory compliance: OCEAView meets the requirements of the most stringent standards (GMP, FDA 21 CFR Part 11, ISO 17025), with event logging, user management and audit trail.
- Scalability: the system adapts easily to your needs. You can add new sensors or extend coverage without having to rethink the entire architecture.
- Simple to use: the intuitive web interface makes it easy to get to grips with the system, with customizable dashboards, automated reports and clear visualisations of critical data.
- Traceability and data security: information is stored securely, with historical data accessible at any time for audits, inspections or internal analysis.
With Dickson and OCEAView, you have full control over your critical environment while simplifying your compliance and quality control processes.
