SOS helps accuracy under pressure

New from Omega, the PXM4200 Series pressure transducers bring state-of-the-art silicon-on-sapphire (SOS) sensor technology to the industrial arena.

New from Omega, the PXM4200 Series pressure transducers bring state-of-the-art silicon-on-sapphire (SOS) sensor technology to the industrial arena.

The SOS construction uses very stable silicon strain gauges on a sapphire carrier, which is bonded to a titanium diaphragm.

This combination provides a very durable transducer, which has excellent stability over a wide temperature range of -50 to +120C.

The transducer is loop powered with a 4-20mA output.

Process connection is made via a 0.25in BSP male fitting with all titanium-wetted parts.

The unit has 0.25% accuracy with zero and span adjustment in ranges from 500mbar to 1500bar.

Electrical connection is made via a standard DIN connector with the option of a plug on loop-powered 3.5-digit LED display, available with intrinsically safe version for hazardous areas or set-point with open collector output.
