Pressure Sensors, Transmitters & Gauges
Pressure sensors, transmitters, and gauges are essential instruments for measuring and monitoring pressure in industrial systems. RSP Supply offers a comprehensive selection of pressure measurement devices designed for use in applications such as pipelines, storage tanks, hydraulic systems, pneumatic systems, and process control environments. These instruments support accurate pressure monitoring to help maintain system safety, performance, and reliability.
Pressure gauges are mechanical, direct-reading devices that display pressure locally in units such as PSI. They are commonly used for basic pressure indication in hydraulic and pneumatic systems where a visual reference is sufficient. Pressure sensors and transmitters, on the other hand, are used when pressure data must be integrated into automated control systems. Gauge pressure sensors measure pressure relative to atmospheric pressure, making them ideal for applications where overpressure or system pressure must be monitored against ambient conditions.
Pressure transmitters are designed for continuous, real-time pressure monitoring in critical industrial processes. They collect signals from the measuring element and convert them into standardized output signals, such as 4–20 mA, that can be transmitted over long distances to PLCs, RTUs, or control systems.
FAQs
Q: What is the difference between a pressure gauge and a pressure transmitter?
A pressure gauge provides a local, mechanical indication of pressure, while a pressure transmitter sends an electrical signal to a control or monitoring system for automation and data processing.
Q: What is a gauge pressure sensor used for?
A gauge pressure sensor measures pressure relative to atmospheric pressure and is commonly used in pipelines, tanks, and industrial systems where overpressure conditions must be monitored.
Q: Can a gauge pressure transmitter measure absolute or differential pressure?
No, gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute and differential pressure measurements require transmitters specifically designed for those measurement types.
Q: What pressure ranges are available for industrial pressure sensors?
Industrial pressure sensors are available in a wide range of positive pressure ratings, from a few millibars up to 10,000 PSI or higher, depending on the application and sensor design.
Q: What is the role of a transmitter in instrumentation systems?
A transmitter collects information from a measuring element, interprets the signal, and sends it to a control system using standardized communication methods such as 4–20 mA or digital protocols.
