Endress+Hauser Cerabar-S pressure transmitter

Tuesday, 10 May, 2005 | Supplied by: Endress+Hauser Australia Pty Ltd



Endress+Hauser's Cerabar-S pressure transmitter is for measuring absolute or gauge pressure of gases, steams or liquids in paper and pulp applications.

For low-pressure applications (full vacuum up to 40 bar), the Cerabar-S incorporates the ceramic cell, Ceraphire. With its 99.9% Al2O3 purity, Ceraphire is more resistant to mechanical abrasion and damage in pulp applications and more chemically inert than the original ceramic cell. The material is up to 30 times thicker than metal membranes, oil-free and can be flush mounted in applications up to 150°C.

For higher-pressure applications up to 700 bar, the Cerabar-S incorporates a mono-silicone cell with stainless steel diaphragm which can withstand temperatures up to 180°C. For applications up to 350°C, chemical seals are available. Accuracy is now 0.05% of the measured variable, and stability is 0.05% of the upper range limit/year. All internationally accepted Ex approvals are available, ATEX, FM, CSA, as well as IEC.

The Cerabar-S incorporates a HistoROM/M-DAT, a chip that stores a wide range of data including the last 25 hours of process variables, temperature and pressure the configuration settings of the transmitter (which can be uploaded and downloaded as required) and event recording (with electronic signatures). This enables speedy troubleshooting and retrospective analysis in the event of a problem in the process, and also allows the device to be readily transferred from one process to another together with relevant calibration data.
