Product Overview
The Aplisens PRE-28 is configured per application (DP range, output type 4–20 mA or 0–10 V, process connection, housing style, and approvals such as ATEX/IECEx and SIL). To ensure proper selection and accurate pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com for a custom quote.
The Aplisens PRE-28 is a differential pressure transmitter for measurement of differential pressure of gases, vapours, and liquids. It uses a piezoresistive silicon sensor separated from the process media by a diaphragm and manometric fluid, and is designed to withstand pressure surges/overloads up to 413 bar. :contentReference[oaicite:0]{index=0}
