The IFM PM1103 is a flush pressure sensor designed for reliable pressure measurement in hygienic and demanding process applications. It provides a measuring range of -1 to 25 bar, allowing both vacuum and positive pressure monitoring in industrial process systems. The flush-mounted design helps minimize dead spaces and supports hygienic installation where cleaning performance is important. The sensor provides a scalable 4...20 mA analogue output and IO-Link communication for flexible integration with modern automation systems. Its stainless-steel construction, high temperature capability and IP67, IP68 and IP69K protection make it suitable for demanding food and beverage process environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PM1103 is designed for process applications where hygienic pressure measurement and easy cleaning are essential. Its flush-mounted construction positions the measuring surface directly at the process connection, helping minimize dead spaces where process media could accumulate. This design is especially useful in food and beverage processing equipment and other sanitary installations. The sensor is designed to withstand high-force cleaning and aggressive cleaning chemicals used in industrial sanitation processes. Its robust construction provides dependable pressure monitoring while supporting hygienic process requirements.
The PM1103 provides a measuring range of -1...25 bar, corresponding to approximately -14.6...362.6 psi or -0.1...2.5 MPa. This range allows the sensor to monitor vacuum conditions as well as higher positive pressures in process equipment. The analogue start point can be configured from -1 to 20 bar, while the analogue end point can be configured from 4 to 25 bar. Adjustment can be made in increments of 0.01 bar, providing flexibility when configuring the sensor for different process requirements.
The PM1103 uses a durable stainless-steel construction intended for demanding process environments. Its housing is designed to withstand moisture, cleaning procedures and other challenging industrial conditions. The sensor supports medium temperatures from -25 to 150 °C, while the ambient operating temperature is -25 to 80 °C. Its IP67, IP68 and IP69K protection ratings provide a high level of protection against water and intensive cleaning conditions. The combination of robust construction and hygienic design makes it suitable for continuous operation in automated process systems.
The PM1103 offers both a scalable 4...20 mA analogue output and IO-Link communication, providing flexible connectivity with industrial control systems. The analogue output can be configured according to the required pressure range, while IO-Link allows digital transmission of pressure data, device status and diagnostic information. The IO-Link interface uses COM2 at 38.4 kBaud and conforms to IO-Link revision 1.1. The sensor operates from 18...30 V DC and includes reverse-polarity, short-circuit and overload protection for dependable industrial operation.
