Cerabar-S pressure transmitter

The Cerabar-S measures up to 700 bar, operates in direct contact with the process at temperatures up to 350°C and comes with an extensive range of process connections for various applications, from mining to offshore.

For low-pressure applications (full vacuum up to 40 bar), the Cerabar-S incorporates the ceramic cell - with Ceraphire cell now fitted as standard. Due to its 99.9% Al2O3 purity, Ceraphire is resistant to mechanical abrasion and damage 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 used in applications up to 150°C.

For high-pressure applications up to 700 bar, the Cerabar-S incorporates a mono-silicone cell with stainless steel diaphragm. This version tolerates temperatures up to 280°C without the need for chemical seals. 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.

Both versions feature secondary containment design, in which the sensor compartment is mechanically separated from the electronics compartment in order to eliminate the possibility of harm to the operators in the event of a process accident.
