Core Highlights of the ME 751 Ceramic Pressure Transducer

The ME751 Pressure Sensor is a highly versatile and efficient device designed to accurately measure pressure levels across a wide range of applications. With pressure ranges from 1.6 to 400 bar (20 to 5000 psi), it can handle various pressure requirements with ease. The sensor operates on piezoresistive technology with signal conditioning, ensuring precise and reliable readings. Its monolithic structure and 18.00mm diameter make it compact and easily integrated into different systems. 

The ME751 Pressure Sensor is specifically designed as a gauge pressure type, making it ideal for monitoring pressure relative to atmospheric pressure. The sensor provides a current loop 4 – 20 mA signal output, facilitating seamless integration into existing control and data acquisition systems. Whether in industrial processes, automotive applications, or other pressure-sensitive environments, the ME751 excels as a dependable and accurate pressure measurement solution.

Features

The excellent resistance to corrosion and abrasion of the ME 751 Ceramic Pressure Transducer makes it highly suitable for use in harsh environments where aggressive chemicals or abrasive media are present. This property ensures long-term reliability and durability, especially in industries such as chemical processing, water treatment, and food and beverage production, where exposure to corrosive substances is common.

Another key application is signal conditioning, which refers to the transducer’s ability to provide a stable and accurate electrical output that can be easily integrated with various control and monitoring systems. The ME 751 is designed to deliver precise measurements, making it ideal for use in process automation, industrial instrumentation, and any application where accurate pressure data is critical for system performance.

The transducer is also EMC compliant, meaning it is engineered to resist electromagnetic interference. This compliance is essential in environments with high electrical noise, such as manufacturing plants or facilities with heavy machinery, ensuring that the pressure readings remain accurate and unaffected by external electromagnetic fields.

Thermally compensated design is another important feature of the ME 751, allowing it to maintain accuracy across a wide range of temperatures. This makes the transducer suitable for outdoor installations or applications with fluctuating temperatures, such as HVAC systems, automotive testing, and environmental monitoring.

Finally, the ME 751 offers zero stress mounting software, which ensures that the sensor is installed without introducing mechanical stresses that could affect its performance. This feature is particularly valuable in precision applications, such as laboratory instrumentation or high-accuracy industrial processes, where even minor installation stresses could lead to measurement errors.
