Notable Product Features: ME 509 Ceramic Pressure Transducer

The ME509 Pressure Sensor is a versatile and reliable device designed to measure pressure with precision. It offers different pressure ranges, including 0.2, 0.5, and 1 bar, or 3, 7, and 14 psi, allowing for various applications. The sensor accommodates both absolute and gauge pressure types, offering flexibility in monitoring different systems. 

Utilising piezoresistive technology, the ME509 ensures accurate and consistent measurements. It’s 32.00.00 mm diameter and flush mount structure make it suitable for integration in compact spaces. The sensor provides a differential mV/V signal output, enabling easy interpretation and integration into compatible systems. With its robust construction and advanced technology, the ME509 Pressure Sensor is a reliable choice for a wide range of pressure measurement tasks.

Features

The high sensitivity, low nominal pressure values of the ME 509 Ceramic Pressure Sensor make it ideal for applications where detecting even the slightest changes in pressure is crucial. This feature is particularly valuable in medical devices, environmental monitoring, and laboratory instrumentation, where precise and accurate pressure readings at low ranges are essential for safety and performance.

Another key advantage is its excellent resistance to corrosion and abrasion. The ceramic diaphragm construction ensures that the sensor can withstand harsh environments, including those with aggressive chemicals or abrasive media. This makes the ME 509 suitable for use in industrial process control, chemical processing, and water treatment plants, where long-term durability and reliability are required despite exposure to challenging substances.

The sensor is also thermally compensated, which means it maintains accurate performance across a wide range of temperatures. This characteristic is especially important in outdoor or industrial settings where temperature fluctuations are common. Applications such as HVAC systems, automotive pressure monitoring, and food processing benefit from this stability, ensuring consistent readings regardless of environmental changes.

Finally, the ME 509 offers extended customisation, allowing it to be tailored to specific application requirements. Whether it’s adapting the sensor for different pressure ranges, electrical outputs, or mechanical fittings, this flexibility enables integration into a wide variety of systems. Customisation is particularly useful for OEMs and system integrators who need a pressure sensor that fits seamlessly into their unique products or processes.
