FAQS

What is a pressure sensor used for?

A pressure sensor detects and converts pressure into an electrical signal, allowing accurate measurement of gases or liquids in applications such as HVAC systems, water pumps, hydraulic machinery, and industrial automation.

How do I choose the right pressure sensor?

Choosing the right pressure sensor depends on factors like pressure range, media compatibility, output signal, accuracy requirements, installation environment (e.g., explosive or high-temp), and whether you need absolute, gauge, or differential measurement.

What is the difference between pressure sensors and transmitters?

A pressure sensor measures the pressure and often provides a raw or analog output. A pressure transmitter includes signal conditioning and amplification, providing a standardized output (e.g., 4-20mA or RS485) for easier integration into systems.

What are the types of pressure sensors?

Common types include gauge pressure sensors, absolute pressure sensors, differential pressure sensors, hydraulic pressure sensors, high-temperature sensors, explosion-proof sensors, and miniature or digital sensors.

Where are pressure transmitters commonly used?

Pressure transmitters are widely used in HVAC control systems, water supply and treatment, hydraulics, pneumatic systems, oil & gas, process industries, food processing, and smart building management.
