Standard Digital Displacement Sensors | Gauge Probes

A pneumatic displacement sensor (gauge probe) allows the number of parts in the fixture to be reduced resulting in improved reliability and reduced fixture cost. It also allows for fast automatic loading of the part into the gauge as the displacement probe tip can be in the fully ‘retract position’ when this is occurring.

The benefit of using a pneumatic push displacement sensor (gauge probe) compared to a spring push probe is that there is less need to design mechanisms to bring the contact senor tip onto the part being measured thus simplifying the overall gauge design.

One issue with pneumatic push displacement probes is that the air inflates the probe gaiter to push the contact sensor tip onto the part being measured. If the gaiter becomes damaged it may not inflate and therefore the probe cannot operate. The Pneumatic Piston Push (Jet) probe uses an internal piston so will continue to operate even if the gaiter is damaged. Air is bled out from a small hole near the front of the contact sensor to allow for retraction therefore the sealing (IP50) may not be suitable for all applications.

The pneumatic piston push displacement probes (gauge probes) like all the digital gauge probes have advantages over traditional LVDT sensors.
Combining multiple sensors using the Orbit Digital Measurement network is easy and data can be read using a Solartron readout or the Gauge Computer Software making system integration simple.

Attention to detail in both design and manufacture of the displacement sensor ensures precision measurement throughout the linear displacement transducer's life.

Solartron Metrology offers a large range of displacement sensors to suit multiple applications with different cable outlets (radial or axial), multiple measuring ranges, different cable types like steel braided which provides additional protection for displacement sensors that are being used in harsh environments.
