Differential pressure transducers determine the pressure difference between two points. The performance of a filter inside a system can be continuously monitored with a differential pressure transducer. An operator can see the state of the filter in real time by using a differential pressure transducer and the output signal from the pressure transducer. As a result, the system will only need to be shut down periodically for examination. Because it avoids potential compounded inaccuracies and the requirement to calculate the difference between two transducers, using a differential pressure transducer is advised over using two individual pressure transducers.

A piezo-resistive or thin-film pressure sensor serves as the pressure transducer. This gadget features a pressure sensor and a device body connected by an electrical circuit. The pressure sensor converts the physical pressure change it detects into an electronic value that may be used in calculations. The pressure transducer transforms only a physical pressure measurement into an electrically readable value. The transducer does not standardize or compensate for pressure measurements.
Types of Differential Pressure Transducers
Wet-to-Wet Transducers
A wet-to-wet differential pressure transducer is employed when taking the appropriate measurement with a liquid on both the high and low-pressure ports. An electrical signal, often a voltage or current output, is created by linearizing the pressure difference between the high and low-pressure ports. The differential pressure for these sensors can be calculated using two independent sensors or a single diaphragm with fluid pushing on both sides of the transducer.
Application of Wet-to-Wet Transducers
Wet-to-wet transducers are frequently employed in HVAC applications for building management, including filter status, strainer basket monitoring, chiller efficiency, and pump suction and discharge. Additionally, these sensors are utilized in pressure tanks and industrial applications.
Wet-to-Dry Transducers
At the wet port, where fluid can be applied, a wet-to-dry differential pressure transducer has a single metal wet-diaphragm. The dry port exposes the internal circuitry to the medium, and only pure dry gas should be applied to it because it has an open electrode. The quantity of airflow that causes the diaphragm to move against the water flow is used to calculate pressure. It is crucial to remember that water cannot be utilized in the dry port or on both sides.
Dry-to-Dry Transducers
A dry-to-dry differential pressure transducer is used in applications where the key measurement is carried out using air or a non-corrosive gas on both the high and low-pressure ports, similar to a wet-to-wet transducer. The pressure differential between the high and low-pressure ports is linearized to produce an electrical signal, frequently a voltage or current output. These sensors are constructed from a single diaphragm that deflects in one of two directions. The result is linearized to give an electrical output similar to the wet-to-wet differential transducer.
Application of Dry-to-Dry Transducers
For low monitoring pressure of less than 3 PSI, a dry-to-dry transducer is more frequently employed. However, high-pressure Test & Measurement applications can also use the sensor design. Dry-to-dry transducers are frequently utilized in clean rooms, isolation rooms, filter status, leak detection, and stairwell pressurization.
How the Transducer Works
- Line pressure, also known as upstream pressure, travels to the system's filter. The upstream pressure can flow to the high side of the differential pressure transducer thanks to a pipe fitted as a pre-filter.
- The filter allows media to pass through while removing any impurities.
- The system continues to be filled with the post-filter downstream pressure. The downstream pressure can flow to the low side of the differential pressure transducer thanks to a pipe installed post-filter.
- As impurities are eliminated over time, the filter will eventually become clogged. As a result, the downstream pressure will drop, increasing the difference between P1 and P2. The transducer's linear output signal will grow as the difference does.
Advantages of Differential Pressure Transducers
