The IFM PL5401 is a compact flush pressure transmitter designed for reliable relative pressure measurement in industrial and mobile applications. It provides a 0 to 250 bar measuring range with a 4 to 20 mA analogue output for continuous pressure transmission to PLCs, controllers and automation systems. Its thin-film measuring cell with diaphragm seal technology supports reliable measurement of liquids, gases, viscous media and liquids containing suspended particles. The robust stainless-steel housing provides excellent resistance to shock and vibration while maintaining stable measurement performance. Its compact construction, IP67/IP69K protection and flush-mountable design make it suitable for demanding pressure measurement installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PL5401 is designed for flush mounting in industrial pressure measurement systems where reliable contact with the process medium is required. It uses a thin-film measuring cell with diaphragm seal technology to detect relative pressure accurately across its measuring range. The sensor covers 0 to 250 bar, equivalent to 0 to 3625 psi or 0 to 25 MPa. Its design is suitable for liquids, gases, viscous media and liquids containing suspended particles. This makes the transmitter appropriate for hydraulic systems, industrial machinery and process equipment where dependable pressure monitoring is required.
The PL5401 provides a continuous 4 to 20 mA analogue current output, allowing the measured pressure value to be transferred directly to industrial controllers and PLC analogue input modules. Its repeatability is better than ±0.05 % of span under specified temperature conditions, while linearity deviation remains below ±0.1 % BFSL or ±0.2 % LS. The device provides a characteristic deviation below ±0.5 % of span and hysteresis deviation below ±0.2 %. Its approximately 2 ms analogue output step response allows pressure changes to be transmitted quickly to connected automation equipment.
The transmitter uses a compact cylindrical stainless-steel housing designed for demanding industrial environments and restricted installation spaces. The housing uses 17-4 PH/630 stainless steel, 316L stainless steel and PEI, while wetted parts use stainless steel and FKM. The PL5401 can withstand shock levels of 50 g for 11 ms and vibration levels of 20 g from 10 to 2000 Hz. Its static pressure rating is 625 bar, with a minimum bursting pressure of 1200 bar, providing strong mechanical resistance for high-pressure applications.
The PL5401 operates from 8.5 to 36 V DC and uses an M12 A-coded connector for industrial electrical integration. Reverse polarity, short-circuit and overload protection help protect the transmitter during operation and installation. The G 1/4 external threaded process connection provides straightforward mechanical integration into compatible pressure systems. IP67 and IP69K protection allows the transmitter to operate reliably in environments exposed to dust, moisture and demanding cleaning conditions.
