Baumer Pressure Transmitters are high-precision devices designed to measure the pressure of liquids, gases, or vapors in industrial systems. These transmitters convert pressure readings into an electrical signal that can be read and processed by control systems, such as PLCs or DCS (Distributed Control Systems). Baumer pressure transmitters are widely used in applications where accurate and reliable pressure measurement is crucial, such as in process industries, HVAC systems, food and beverage manufacturing, and chemical processing. Key Features of Baumer Pressure Transmitters High Accuracy and Precision: Baumer pressure transmitters are designed for high accuracy, typically in the range of ±0.1% to ±0.5% of full-scale output. This level of precision ensures that measurements are reliable and repeatable, crucial for process control, quality assurance, and safety applications. Wide Pressure Range: Baumer offers a broad selection of pressure transmitters that can measure low to high pressures, with ranges from 0 to 100 mbar up to 0 to 1000 bar or even higher. This variety allows Baumer transmitters to be applied in a wide range of applications, from low-pressure vacuum systems to high-pressure industrial processes. Robust Construction: Baumer pressure transmitters are built to withstand harsh industrial environments. They feature durable housing made from materials such as stainless steel and are often rated for protection against environmental factors, such as dust and water, with IP65, IP67, or higher ingress protection ratings. They are designed to handle extreme conditions like high temperatures, vibrations, and chemicals. Depending on the application, Baumer transmitters can operate in temperature ranges from -40°C to +125°C or even higher. Wide Variety of Measuring Principles: Baumer pressure transmitters use different principles of measurement, including: Strain Gauge Technology: Commonly used for general-purpose applications, offering a good balance between cost, accuracy, and reliability. Capacitive Pressure Sensing: Often used for applications requiring high accuracy and stability over time. Piezoelectric Pressure Sensing: Suitable for dynamic pressure measurements, especially in systems that require fast response times. Analog and Digital Outputs: Baumer pressure transmitters offer both analog (4-20 mA, 0-10 V) and digital (e.g., IO-Link, Modbus, HART) output options. The analog output is commonly used in traditional control systems, while the digital output allows for higher precision and integration with modern automation networks. IO-Link enables advanced features such as remote parameter configuration, diagnostics, and real-time data exchange, making it suitable for Industry 4.0 applications. Stability and Long-Term Reliability: Baumer transmitters are known for their long-term stability, which is essential in applications where maintenance is infrequent or systems run continuously. These transmitters are designed to provide consistent measurements over time, reducing the need for recalibration or replacement. Hygienic and Sanitary Designs: Some Baumer pressure transmitters are specially designed for hygienic applications, particularly in the food, beverage, pharmaceutical, and biotechnological industries. These models are designed with easy-to-clean materials (like stainless steel) and are often compliant with standards like EHEDG (European Hygienic Engineering & Design Group) and 3A for sanitary equipment. Temperature Compensation: Baumer pressure transmitters are equipped with temperature compensation features to ensure accuracy across a wide range of operating temperatures. This helps maintain precise readings even in fluctuating temperature environments, which is important in many industrial processes. Long-Term Stability and Low Drift: Baumer pressure transmitters are designed to maintain their accuracy over long periods with minimal drift. This is particularly useful for applications where continuous monitoring is critical, reducing the need for frequent recalibration. Explosion-Proof and Hazardous Area Versions: For use in hazardous environments (e.g., in the chemical, oil and gas, or mining industries), Baumer offers explosion-proof and intrinsically safe pressure transmitters that comply with international safety standards (such as ATEX, IECEx, CSA). Common Applications of Baumer Pressure Transmitters Process Control: Baumer pressure transmitters are used in industries like oil and gas, chemicals, and power plants to monitor and control pressures in piping systems, vessels, and tanks. These applications include monitoring process pressures, controlling compressors, or ensuring safe operating conditions. Hydraulic and Pneumatic Systems: In applications like hydraulic presses, pneumatic systems, and fluid power systems, Baumer pressure transmitters provide essential feedback to monitor system performance and ensure that pressures remain within safe limits.
