NewTek Gage Head Sensors Avoid Damage Between Inspection Readings

(NewTek: Pennsauken, NJ) — NewTek GAR series spring-loaded gage heads are used in automated dimensional gaging applications as part of inline inspection processes where the sensor probe must move out of the way between readings. The probes of these LVDTs extend when taking dimensional measurements, then retract to their original position to avoid damage to the sensor and prevent damaging the next conveyed product.

Quality Digest


The GAR series gage head sensors check dimensions when their probes contact the measured object. In operation, low-pressure air (10–40 psi) extends the sensor shaft. Probe contact force is regulated by the air pressure. With the removal of air pressure, an internal spring retracts the probe to allow room for automated parts to move along the conveyor without damaging the probe or next product.
