Product Overview
The Aplisens PRE-28.SMART is configured per application (DP range, process connection style, casing/IP rating, and approvals like Ex ia / Ex d / marine). For correct selection and accurate pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens PRE-28.SMART is a smart differential pressure transmitter with 4–20 mA output + HART for configuration, diagnostics, and integration into PLC/SCADA systems. It supports intrinsic safety (ATEX/IECEx) and explosion-proof (ATEX/IECEx) versions, with static pressure ratings up to 413 bar (configuration dependent).
- Signal: 4–20 mA + HART
- Accuracy: ±0.1% of calibrated range
- Static pressure limit: up to 413 bar (C-type, option dependent)
- Wetted parts: SS316L (diaphragm options include Au)
- Approvals: Ex ia / Ex d (ATEX, IECEx), marine certificates (DNV, BV)
- Multiple housings: IP65 / IP66 / IP67 / IP68 options (depending on casing)
- Process connections: manifold mount (C / CH) or threaded (GP / PN), plus diaphragm seal option
Tell us your DP range, static pressure requirement, process connection style, and required approvals (Ex ia / Ex d / marine), and we’ll confirm the correct build for your application.
