About Digital Differential Pressure Gauges & Controls
Sensocon digital differential pressure gauges and controls are the modern replacement for mechanical differential pressure gauges. They deliver higher accuracy, richer features, and better usability for HVAC, cleanrooms, labs, dust collection, and industrial airflow applications. If your project also requires wireless retrofits or remote monitoring, see our wireless monitoring applications by industry .
Where Digital Differential Pressure Fits Best
- Filter & coil monitoring: track pressure drop and maintenance intervals without guesswork.
- Room pressurization: support containment and cleanliness goals in critical spaces.
- Airflow / velocity measurement: measure flow when paired with an appropriate sensing device.
- Control applications: use programmable relays for alarm, fan control, damper logic, or process interlocks.
Key Features
- Retrofit-friendly mounting: designed to fit the same panel cutout as Dwyer® Magnehelic® and Sensocon® Series S2000 for fast upgrades.
- Optional 4–20 mA output: ideal when you need a transmitter output in addition to local display.
- Wide-range power options: universal power (24–240 VAC/VDC) simplifies specification across facilities.
- Programmable relay outputs: setpoints, delays, and relay action support control and alarming.
- Accuracy options: multiple accuracy grades available to match the application.
Need Wireless Differential Pressure Monitoring?
If running new wire is difficult or you want remote alarms and trends, consider wireless differential pressure options within our wireless monitoring applications by industry . Wireless is often ideal for retrofit projects, distributed assets, and hard-to-reach locations.
Looking for a Mechanical Differential Pressure Gauge?
If your application does not require a digital display or electronic outputs, a traditional mechanical gauge may be a better fit. The Sensocon Series S2000 is commonly used as a Magnehelic replacement with compatible mounting dimensions and similar performance characteristics.
