KROHNE presents new pressure transmitter with ceramic diaphragm

With the new OPTIBAR PC 1010, KROHNE now also offers a version with a ceramic diaphragm in the ultra-compact pressure transmitter range. As a result, users can now also benefit from the advantages of the material in low-cost, small pressure transmitters. Thanks to its measuring cell made of high-performance ceramics, the gauge pressure transmitter offers significantly increased resistance to pressure surges, water hammer, abrasion and corrosion compared to metallic diaphragms. This makes the OPTIBAR PC 1010 particularly suitable for water applications in which the jerky start-up of pumps can severely damage the stainless-steel measuring cell of conventional pressure transmitters.

Robust design with IP68 option
For pump control in manholes prone to flooding, the pressure transmitter is available as an IP68-rated version designed to be waterproof. Thanks to its robust design, the pressure transmitter is also ideal for long-term stable pressure and level measurement in many other industries as well as in factory automation. It offers a cost-effective solution for simple applications with gases, vapours and liquids up to 40 bar and temperatures up to +125°C / +257°F.

High level of safety
The dry capacitive measuring cell of the pressure transmitter ensures increased process reliability. It works without filling oil. Leakage of filling oil into the process is therefore ruled out from the outset by the design. The OPTIBAR PC 1010 is available with both a recessed and a front-flush ceramic diaphragm. The pressure transmitter is extremely temperature and long-term-stable and has excellent accuracy for its device class. It is also available in an intrinsically safe version with ATEX/IECEx approval for use in Zone 0.
