How a differential pressure transmitter works
The transmitter compares pressure levels at two locations in a system, providing critical data for monitoring airflow, filter status, and system performance.
Using advanced sensor technology, the device translates pressure variations into a readable electrical output that can be transmitted to control systems.
Data is sent instantly to your building management or automation system, allowing for immediate adjustments to maintain optimal performance.
By tracking pressure trends over time, you can identify potential issues before they escalate, reducing downtime and extending equipment lifespan.

Frequently Asked Questions (FAQs)
Our dedicated team is ready to assist you with any questions or specific requirements you may have.
01
01
Differential pressure transmitters are primarily used for flow, level, and pressure measurement in various industries. They are essential for monitoring filter conditions in HVAC systems, measuring fluid levels in tanks, and calculating flow rates in pipelines for both liquids and gases.
02
02
A differential pressure transmitter measures the difference between two pressures applied to opposite sides of a sensing diaphragm. This pressure difference causes the diaphragm to deflect, which is then converted into an electrical output signal, typically 4-20 mA, proportional to the differential pressure.
03
03
Selecting the right sensor depends on factors like the process medium (liquid, gas, or steam), operating temperature and pressure, required accuracy, and environmental conditions. You also need to consider the necessary output signal, such as 4-20mA with HART, for compatibility with your control system.
04
04
A pressure transmitter measures pressure relative to a reference, such as atmospheric pressure (gauge) or a full vacuum (absolute). In contrast, a differential pressure transmitter measures the difference between two separate pressure points, making it ideal for flow and level measurement applications.
05
05
Common failure causes include overpressure, corrosion of wetted parts, vibration, extreme temperatures, and improper installation. Regular maintenance and selecting a transmitter with the appropriate materials and specifications for your application can help prevent these issues.
06
06
Calibration involves applying a known, stable pressure to the high and low ports of the transmitter and adjusting the output signal to match. This process typically requires a pressure calibrator and involves checking the zero point, mid-range, and full span to ensure linearity and accuracy.
07
07
Routine maintenance includes periodic calibration checks, inspecting for leaks or physical damage, and ensuring the impulse lines are clear of blockages or condensation. Keeping the sensor clean and verifying electrical connections are secure will help ensure its long-term reliability and performance.
