Skip to the content At Comptus, we design barometric pressure sensors that deliver precise and reliable readings in even the toughest environments. Whether you’re monitoring weather conditions, controlling ventilation systems, or tracking elevation changes, our barometric sensors provide dependable performance you can trust.
In simple terms, an atmospheric pressure sensor measures barometric pressure, which is the measure of air pressure in the atmosphere. More specifically, this measures the degree of weight that air molecules exert anywhere in the world. Tracking rising or dropping barometric pressure is a reliable indicator of changing weather.
By monitoring pressure differential, control systems can automatically regulate ventilation for improved building performance. Comptus barometric sensors are engineered for consistent accuracy, helping technicians, engineers, and researchers make informed decisions based on real-time data.
The Comptus A70-P Barometric Pressure transmitter utilizes a 4-20mA signal to integrate with all common control systems. Also available are A70H series combined humidity, temperature and pressure sensors utilizing a RS485 protocol. Call us for more information on our barometric pressure sensors, barometric pressure measurement instruments, and instruments for measuring atmospheric pressure. We also offer a range of wind and industrial environmental sensors, atmospheric pressure sensors, barometric pressure gauges, transmitters and controls.

With Comptus, you’re not just buying a sensor — you’re investing in long-term accuracy and quality craftsmanship.
Our barometric pressure measurement instruments are used in a wide variety of industries and research settings:
Wherever accurate atmospheric data matters, Comptus barometric sensors deliver consistent performance.
When choosing a barometric pressure sensor, keep these factors in mind:
If you’re unsure which model fits your setup, our technical team is happy to guide you through the selection process.
For over three decades, Comptus has been a trusted manufacturer of precision weather and environmental instrumentation. Our barometric pressure sensors reflect that commitment to quality designed, built, and tested in the USA for dependable, professional use.
Contact us today to learn more or request a quote for your barometric pressure gauge. Our experts will help you choose the ideal configuration for your specific application.
When choosing a barometric pressure sensor, check for a range around 900–1100 mbar (27–31 inHg), high accuracy with minimal drift, and compatible outputs such as 4–20 mA or RS-485 for easy integration with monitoring or control systems.
They’re commonly used in weather stations, HVAC and ventilation systems, industrial process control, and altitude tracking applications, anywhere accurate atmospheric data is essential for safety, performance, or research.
Most sensors come factory-calibrated and need recalibration only once a year or if you notice drift. For harsh environments or critical applications, more frequent checks may be required to maintain accuracy.
Yes, many models are built for outdoor use. Ensure they are properly vented to the atmosphere but protected from direct rain, wind, and moisture to prevent inaccurate readings or damage.
Both terms often describe the same device - a barometric pressure measurement instrument. “Gauge” refers to the measuring function, while “sensor” emphasizes its ability to output data electronically for integration with systems.
Consider your required pressure range, accuracy, and environmental conditions. Make sure the output type matches your system and choose a reliable manufacturer like Comptus that provides durable, calibrated, and easy-to-integrate barometric pressure instruments.
Comptus is a leading producer of quality wind and industrial environmental sensors, transmitters and controls.
