How Pressure Transducers Work: Principle, Types & Applications
A pressure transducer converts pressure into an electrical signal, facilitating alarm systems and output control. The focus here is on the Cerabar PMP135 by Endress+Hauser, which employs a metallic diaphragm and fluid to generate electrical signals via an electronic strain gauge. This compact and hygienic sensor supports easy installation and is suitable for various cleaning processes. It functions within a temperature range of -10°C to 100°C and outputs a 4-20 mA current for PLC input, allowing real-time pressure monitoring. The transducer maintains a proportional relationship between current flow and pressure readings, enhancing operational efficiency.
