Pressure Transducers

Pressure transducers are precision electronic sensing instruments widely utilized in industrial process control systems to measure and monitor pressure in various process media, including gases, liquids, vapors, and viscous substances. They convert applied pressure into an electrical signal—typically analog outputs such as 4-20 mA, 0-10 V, or digital communication protocols like HART or Foundation Fieldbus—for accurate, real-time monitoring and control.

In industrial settings such as chemical plants, refineries, power generation facilities, pharmaceutical manufacturing, water and wastewater treatment, oil and gas processing, and food and beverage industries, reliable pressure measurement is critical for process efficiency, safety, and product quality. Pressure transducers in these environments must withstand harsh operating conditions, including high temperatures, extreme pressures, vibration, mechanical shock, and exposure to aggressive media.

Pressure transducers can measure absolute, gauge, differential, or vacuum pressures, depending on process requirements. Absolute pressure transducers are referenced to a perfect vacuum and are used for atmospheric, vacuum, and altitude measurements. Gauge pressure transducers reference atmospheric pressure, making them ideal for applications like process lines and tank-level monitoring. Differential transducers measure the difference between two pressure points, essential for filter monitoring, flow measurements, and fluid dynamics analysis.

Robust construction featuring stainless steel, Hastelloy, titanium, ceramic diaphragms, and sealed housings provides superior chemical compatibility, corrosion resistance, and long-term stability. Industrial transducers carry certifications for hazardous environments, such as ATEX, IECEx, and CSA approvals, ensuring safety compliance and reliable performance in potentially explosive atmospheres.
