The IFM PL5402 is a compact flush pressure transmitter designed for reliable relative pressure measurement in industrial and mobile applications. It provides a 0 to 100 bar measuring range with a 4 to 20 mA analogue output for continuous pressure transmission to PLCs and automation controllers. Its thin-film measuring cell with diaphragm seal technology is suitable for liquids, gases, viscous media and liquids containing suspended particles. The robust stainless-steel housing provides high resistance to mechanical shock and vibration while maintaining reliable measurement performance. With IP67 and IP69K protection, the PL5402 is well suited for demanding installations where compact dimensions and dependable pressure monitoring are required.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PL5402 is designed for flush mounting in industrial pressure measurement systems where the sensing element can be positioned close to the process medium. Its thin-film measuring cell with diaphragm seal technology enables reliable detection of relative system pressure in different industrial media. The transmitter offers a measuring range of 0 to 100 bar, equivalent to 0 to 1450 psi or 0 to 10 MPa. Its flush design makes it particularly useful for applications involving viscous media and liquids containing suspended particles. The compact construction also allows installation in systems where mounting space is restricted.
The PL5402 provides a continuous 4 to 20 mA analogue current output, allowing the measured pressure to be transmitted directly to industrial control systems. Its specified repeatability is better than ±0.05 % of span, while the linearity deviation is below ±0.1 % BFSL or ±0.2 % LS. The transmitter has a characteristic deviation below ±0.5 % of span and a hysteresis deviation below ±0.2 %. With a fast analogue output step response time of approximately 2 ms, the sensor can respond rapidly to changes in system pressure.
The PL5402 is built with a compact stainless-steel housing intended for demanding industrial environments. It provides IP67 and IP69K protection and can operate in ambient temperatures from -25 to 90 °C. The permitted medium temperature is -20 to 90 °C, making it suitable for a broad range of industrial processes. The transmitter is tested for shock resistance up to 50 g for 11 ms and vibration resistance up to 20 g from 10 to 2000 Hz. Its pressure rating is 250 bar, with a minimum bursting pressure of 1000 bar, providing strong mechanical resistance for high-pressure applications.
The PL5402 operates from an 8.5 to 36 V DC supply and uses an M12 connector with A coding for electrical connection. The G 1/4 external threaded process connection supports straightforward integration with compatible pressure systems. The housing uses stainless steel 17-4 PH/630, 316L stainless steel and PEI, while wetted parts use stainless steel and FKM materials. The device has a compact approximately 19 mm diameter housing and a length of 73.8 mm, making it suitable for restricted installation spaces. Reverse polarity, short-circuit and overload protection further support reliable operation in industrial automation systems.
