The IFM PM1104 is a flush pressure sensor designed for reliable pressure measurement in hygienic and demanding process applications. It features a robust stainless-steel housing and a hygienic flush design that helps minimize dead spaces at the measuring point. The sensor measures relative pressure and vacuum across a range of -1 to 10 bar, making it suitable for a wide variety of process conditions. It provides a scalable 4...20 mA analogue output together with IO-Link communication for convenient integration into automation systems. The PM1104 is particularly suitable for food and beverage applications requiring high temperature resistance, reliable measurement and resistance to intensive cleaning processes.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PM1104 is designed for hygienic pressure measurement where a clean and unobstructed process interface is important. Its flush measuring design helps reduce dead spaces around the pressure-sensing surface, supporting applications where process cleanliness is essential. The construction is particularly suitable for food and beverage processing equipment and other sanitary process installations. The sensor is designed to withstand intensive cleaning conditions and aggressive cleaning agents used in industrial environments. This combination of flush construction and robust materials allows dependable pressure monitoring in demanding automated processes.
The PM1104 provides a measuring range of -1...10 bar, corresponding to approximately -14.5...145 psi, -100...1000 kPa or -0.1...1 MPa. This range allows the sensor to monitor both vacuum conditions and positive process pressure within a single device. The analogue start and end points can be configured within specified limits to adapt the output signal to different process requirements. The analogue output is scalable in fine increments, allowing suitable measurement spans to be selected during commissioning. This flexibility makes the sensor useful for different pressure monitoring and control applications.
The PM1104 incorporates a robust stainless-steel housing intended for demanding food and beverage and process environments. Its construction is designed to tolerate high-pressure cleaning and aggressive cleaning agents, helping maintain reliable operation during regular sanitation procedures. The sensor also offers high temperature resistance, with the specified medium temperature range extending up to 150 °C. High protection ratings of IP67, IP68 and IP69K support reliable operation in environments exposed to moisture, water jets and intensive cleaning. These characteristics make the sensor well suited for hygienic industrial installations.
The PM1104 combines a scalable 4...20 mA analogue output with IO-Link communication for flexible industrial integration. The analogue signal can be configured according to the required pressure measurement span, while IO-Link provides digital communication for parameterization and process data exchange. The sensor includes one analogue output and one digital output, with the digital channel supporting IO-Link. It operates from 18...30 V DC and incorporates reverse-polarity, short-circuit and overload protection. This makes the PM1104 suitable for modern automation architectures where both conventional analogue signals and digital sensor communication are required.
