Add to compare

The PRE-28.MODBUS differential pressure transmitter is a high-precision device designed for measuring differential pressure with an accuracy of up to 0.1%. It supports digital communication via Modbus RTU protocol and is certified for intrinsic safety (ATEX, IECEx) and explosion-proof (ATEX, IECEx) applications. The transmitter is suitable for marine environments with DNV and BV certifications and can operate under static pressure up to 413 bar. It offers various electrical connection types (PM12, PM12S, PKD, SG, SGM, PZ2) with different protection ratings (IP65, IP66, IP67, IP68) and process connection options (GP, PN, C, CH) with specific dimensions and materials. The device supports multiple measuring ranges from 0...0.25 bar to -5...70 mbar, with rangeability up to 25:1. It is powered by 4...28 V DC and can output MODBUS RTU or 4...20 mA, with configurable transmission speeds and parity settings. The transmitter is available with various certifications and options for different applications, including oxygen service, static pressure, and NACE MR-01-75 compliance.
