The IFM PM1105 is a flush pressure sensor designed for reliable pressure measurement in hygienic process applications. It features a ceramic-capacitive measuring cell and a flush-mounted construction that helps prevent dead spaces in the process connection. The sensor supports both a scalable 4...20 mA analogue output and IO-Link communication for flexible integration. Its stainless-steel construction provides high resistance to demanding industrial environments and cleaning processes. With a measuring range of -1...4 bar, the PM1105 is suitable for pressure and vacuum monitoring in food and beverage process systems.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PM1105 is specifically designed for applications where hygienic pressure measurement and easy cleaning are important. Its flush-mounted measuring cell creates a smooth measuring surface with no significant dead space around the sensing area. This construction is particularly suitable for food and beverage processing systems where process residues must be minimized. The sensor can handle liquids, gases, viscous media and liquids containing suspended particles. Its process-oriented construction supports reliable pressure monitoring in automated hygienic production equipment.
The sensor uses a ceramic-capacitive pressure measuring cell to provide stable and repeatable pressure measurement. The specified measuring range extends from -1 to 4 bar, allowing the device to monitor both vacuum and positive pressure conditions. The sensor provides a configurable analogue output with a scalable 4...20 mA signal and also supports IO-Link communication. Its repeatability is specified at less than ±0.1% of the span under the stated conditions. The measuring technology makes the PM1105 suitable for continuous pressure monitoring in industrial process applications.
The PM1105 has a robust stainless-steel housing intended for demanding food and beverage environments. Wetted parts include stainless steel 316L, ceramic and PTFE, with the wetted stainless-steel surface specified at Ra < 0.4 µm. The sensor is designed to withstand high-pressure cleaning and aggressive cleaning agents used in industrial hygiene processes. It also provides high temperature resistance, with the medium temperature range extending up to 150 °C. This combination of materials and construction supports dependable operation in demanding process installations.
The PM1105 provides flexible connectivity for modern industrial automation systems through analogue and IO-Link communication. It has one analogue output and one digital output, with the analogue current output configurable from 4...20 mA. IO-Link enables convenient parameterization and communication of sensor information with compatible automation equipment. The sensor operates from 18...30 V DC and includes reverse-polarity, short-circuit and overload protection. Its M12 connection with gold-plated contacts provides a practical interface for industrial installation.
