Differential Pressure Sensors | Transmitters | DP | ΔP

Applied Measurements offer 2 types of differential pressure sensors, wet/wet and dry/dry. Measuring ranges from 0-0.25mbar up to 0-200bar and line pressure / common mode pressures of up to 200bar can be catered for.  For ATEX applications differential pressure ranges from 0-5mbar up to 0-200bar are available.

Our differential pressure sensors are available with output signals of 4-20mA or 0-10Vdc.

Our PR3202 dry/dry differential pressure sensor is ideal for HVAC and cleanroom monitoring as it measures differential pressure of dry, air and non-corrosive gases. And our PR3200 wet/wet differential pressure sensor is suited for filter condition monitoring, flow measurement and hydraulic applications as it designed for the measurement of liquids and gases.

All models can be supplied with digital displays and indicators, signal digitisers, telemetry systems, data loggers and acquisition equipment from our range of transducer instrumentation.  Calibration traceable to UKAS standards is available on all pressure sensors and systems.

What is a Differential Pressure Sensor?

A differential pressure sensor (or differential pressure transducer) is a transducer that measures the difference in pressure between two points.

What is Differential Pressure?

Differential pressure is the difference in pressure between two measurement points in a system.

Care must be taken to ensure that the line pressure, also known as common mode pressure, is within the specification of the sensor to avoid damage.

Differential Pressure Sensor Applications

• Flow and Filtration Monitoring
• Air Filter Monitoring
• Water Filtration
• Fuel Filter Monitoring
• Exhaust Emissions Monitoring

Differential Pressure Air Filter Application Example

Pressure readings in HVAC units (heating, ventilation and air conditioning) for clean rooms, office environments and industrial units must be continually monitored to maintaining a sterile, clean environment. Air filter monitoring can detect dirty or clogged filters which make your filter inefficient and reduce the life of your HVAC unit.

A differential pressure transducer can be used to measure the pressure before and after the filter in an HVAC system.

A difference in pressure between the 2 points before and after the filter could indicate that the filter has become clogged.
