Vista Engineering has developed a novel (patented) method for measuring pressure inside a stainless steel containment structure with no physical penetrations of any kind. A magnet is attached to a bourdon tube (a pressure sensing device common to typical dial-type pressure gauges). As the pressure changes, the magnet rotates just like a gauge's needle would rotate. An indexed and calibrated compass (another magnet) is placed outside the containment, and the poles of the magnets align with each other.  As the sender magnet rotates, the readout magnet rotates, thus measuring the internal pressure. This coupling technology is not limited to pressure sensing. Any sensing that can cause the rotation of the magnet can be coupled out of a sealed container.

Details

This technique works when the barrier between the sensor and the indicator is non-magnetic or weakly magnetic. Six inches or more of solid stainless steel can be penetrated by the magnetic field lines of the sensor's magnet. The first application of this technique has been to measure pressure inside nested stainless steel canisters that have been welded tightly shut. Running wires or sensor tubes out from the inner container would have severely compromised the containment.

Measurements need not be made exclusively by direct observation of a compass needle outside the sealed containers. Vista Engineering also produces a model that uses solid state sensors producing signals suitable for remote data logging.
