Compact pressure transmitter with internal diaphragm

• Robust design with internal stainless steel diaphragm
• Vacuum and overpressure resistant versions for absolute and gauge pressure
• Very short response times (< 50 ms)

With its industry standard process connections the OPTIBAR P 3050 C is universally used for general purpose pressure applications. The transmitter features superb accuracy over a wide temperature and pressure range, compact stainless steel housing, rapid response times and outstanding reproducibility and long term stability.

These features are made possible by using sensors which are extremely stable across a wide range of temperatures and pressure ranges. Additional digital compensation reduces the temperature dependence on the pressure measurement. The measuring cell itself is completely isolated from the actual process via a stainless steel (1.4404 / 316L) diaphragm.

The electronics and the optional display are located in a stainless steel housing ventilated through a Gore-Tex® filter. This ensures that the pressure transmitter is resistant to moisture, shocks and vibration.

The protection category IP65 or IP67 depends on the selection of electrical cable glands.

An internally located push button makes it possible to easily adjust the zero point and measuring range for quick start-up
