The IFM PL2058 is a flush pressure transmitter designed for accurate measurement of very low relative pressure in industrial and process applications. It provides a measuring range of approximately -0.0125 to 0.25 bar, with a configurable 4 to 20 mA analogue output for connection to industrial control systems. Its compact measuring design supports applications where precise low-pressure detection is required. The transmitter provides parameter adjustment for the zero point and span, allowing the analogue signal range to be adapted to application requirements. Its robust stainless-steel construction, IP67 protection and high pressure-cycle capability make it suitable for demanding continuous measurement applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PL2058 is specifically suited for applications where pressure levels are considerably lower than those handled by conventional high-pressure transmitters. Its measuring range extends from -0.0125 to 0.25 bar, equivalent to -12.5 to 250 mbar or -1.25 to 25 kPa. The analogue starting point can be configured between -12.5 and 100 mbar, while the analogue end point can be configured between 50 and 250 mbar. This flexibility allows the transmitter to be adapted to different low-pressure monitoring requirements.
The PL2058 provides a standard 4 to 20 mA analogue current output and supports adjustment of both zero point and span. The factory configuration is specified as ASP 0.0 mbar and AEP 250.0 mbar, while the adjustable analogue start and end points allow the signal range to be tailored to the application. Its maximum load is specified as 550 Ω at a 24 V supply under the stated conditions. The analogue output has a maximum response time of approximately 3 ms, enabling rapid transmission of pressure changes to connected control equipment.
The PL2058 provides repeatability below ±0.1 % of span under specified temperature conditions. Its characteristic deviation is below ±0.6 % of span, while linearity deviation is below ±0.5 % and hysteresis deviation is below ±0.1 %. Long-term stability is specified below ±0.1 % of span per year under the stated turn-down conditions. These characteristics make the transmitter suitable for applications where stable low-pressure signal transmission is important.
The PL2058 uses a cylindrical housing with a diameter of approximately 34 mm and a length of 87 mm. The housing uses 316L stainless steel, PEI and FKM, while wetted components include ceramic measuring material and stainless steel. The sensor is equipped with an Aseptoflex external process connection and an M12 A-coded connector with gold-plated contacts. It provides IP67 protection and is designed to withstand 50 g shock and 20 g vibration from 10 to 2000 Hz, supporting reliable operation in demanding industrial environments.
