SUPCON pressure transmitters deliver high accuracy and stability for industrial measurement. Designed for harsh process environments, they support reliable pressure monitoring and control.
What is a Pressure Transmitter
A pressure transmitter is an industrial instrument designed to measure the pressure of gases or liquids and convert that physical pressure into a standardized electrical signal, typically 4–20 mA or digital communication protocols. This signal can then be transmitted to control systems such as PLCs, DCS, or SCADA platforms for monitoring, automation, and safety control.
SUPCON pressure transmitters are engineered for high accuracy, long-term stability, and reliable performance in demanding industrial environments. They are widely used to measure gauge pressure, absolute pressure, and differential pressure, supporting both direct pressure monitoring and indirect measurements such as flow and level. With multiple mounting options and configurations, SUPCON pressure transmitters provide flexible solutions for process control across chemical, energy, water treatment, and manufacturing industries.
Pressure Transmitter Working Principle
The working principle of a pressure transmitter is based on converting mechanical pressure into an electrical signal. When pressure is applied to the sensing element—such as a diaphragm—the element deforms proportionally to the applied pressure. This deformation is detected by a sensing technology, which then produces an electrical signal corresponding to the pressure value.
Inside SUPCON pressure transmitters, the raw sensor signal is processed through amplification, temperature compensation, and linearization circuits to ensure accurate and stable output under varying operating conditions. The processed signal is then converted into a standardized output that can be reliably transmitted over long distances. This design ensures precise measurement even in harsh environments involving vibration, temperature fluctuations, or corrosive media, making SUPCON transmitters suitable for critical industrial applications.
Types of Pressure Transmitters We Offer
SUPCON offers a comprehensive range of pressure transmitters to meet diverse measurement requirements. Our portfolio includes Differential Pressure Transmitters for flow, filter, and level measurement; Absolute Pressure Transmitters for vacuum and reference-based applications; and Direct Mount Type Pressure Transmitters for compact, inline installations.
We also provide DP Type Pressure Transmitters for combined pressure measurement needs, Level Transmittersbased on hydrostatic pressure principles, and Flange Type Pressure Transmitters for high-temperature, viscous, or corrosive media. For challenging process conditions, Remote Seal Type Pressure Transmitters and Remote Seal Type Differential Pressure Transmitters protect the sensor from extreme temperatures, blockages, or aggressive chemicals. Together, these types ensure full coverage for modern industrial pressure measurement.
