Developed for high wear applications, the ceramic diaphragm is an excellent solution for many applications. Environments include tobacco stock lines, pulp, and paper cleaner systems, wastewater treatment, and other high flow mediums with particulates. This combination of high flow and abrasive materials can, over time, wear down a metallic diaphragm and will permanently lose its zeroing ability as the wear on the diaphragm increases. Not so for ceramic diaphragms; as the process medium wears the ceramic diaphragm down, you re-zero the sensor, and can be done many times over the life of the transmitter. The ceramic diaphragm also gives added stability to the unit. Orientation during calibration does not affect the transmitter.
