NewTek Hermetically-Sealed, Spring-Loaded LVDTs Provide Precision Data for Online Parts Quality Control in Automated Assembly
Pennsauken, NJ, February 18, 2019… NewTek Sensor Solutions introduces an extended family of Spring-Loaded LVDTs for highly accurate and repeatable dimensional gaging of components as part of manufacturing quality assurance systems. Available in AC- and DC-operated versions, these sensors are used in R&D labs for quality testing, printing operations for roller alignment, and automated production lines for dimensional gaging of parts in go/no go inspection. Data collected by NewTek gaging probes are used for online quality control and post-process statistical analysis.
Featuring a stainless-steel, spring-loaded probe assembly and welded ¾-inch diameter hermetically-sealed housing, NewTek Spring-Loaded LVDT Position Sensors are available in ranges from ±0.050” (1.27mm) to ±2” (50.8mm). With near-infinite resolution and excellent repeatability, these gage heads operate at linearity of ±0.15% over wide operating temperature ranges of -65◦F (-54◦C) to 275◦F (135◦C).
Customized versions of NewTek Spring-Loaded LVDTs operate in higher temperatures up to 400°F (204°C) and environments with radiation up to 30MRad. A high-precision gaging probe, available in .315 in (8 mm) and .375 in (9.5 mm) diameters, offers extremely reliable performance in measurement ranges from ±.040” (±1.0 mm) to ±0.200” (±5 mm).
NewTek offers its Spring-Loaded LVDTs in AC, DC voltage, or 4-20 mA current outputs. The AC-operated LVDT gage heads are ideal for operation in higher temperatures as the sensor is segregated from the electronic circuitry. While the LVDT works in a hostile environment, a signal conditioner - that provides power to the sensor and demodulates output - operates remotely in a benign area. (NewTek offers its NTC-600 Signal Conditioner for this task.) The output is displayed locally or downloaded into a PLC for statistical process control.
Where temperature exposure is not an issue, a DC-operated LVDT gage head can eliminate the installation and cost of signal conditioning equipment. With electronics built into the assembly, the sensor simplifies mechanical set-up into automated machinery.
NewTek offers both standard off-the-shelf and custom units with a choice of probe contact tips, custom spring rates, and an optional pneumatic probe. Check out the video at https://www.youtube.com/watch?v=dU4b_fEEI3c that demonstrates how NewTek Spring-Loaded LVDTs identify when parts in an automated production line are out-of-tolerance. Data is sent to a PLC that provides an alarm to operators. For more information on NewTek Spring-Loaded LVDTs, visit https://www.newteksensors.com/spring-loaded-lvdts/.
