Surface Measurement Tools for Quality Control on Automated Assembly Lines
March 1, 2021
NewTek Spring-Loaded LVDTs are used for surface measurement of materials as part of the quality control processes in automotive production plants, among other applications.
Outfitted with precision wheels and other accessories for active monitoring of materials along a line or conveyor, the Spring-Loaded Gage Heads are mounted at different points of the manufacturing line to make multiple contacts of a product surface in precisely measuring its thickness, flatness and other surface parameters. Data collected from the gauging probes enables operators to monitor a product profile for abnormalities or an out-of-tolerance spec.
NewTek Spring-Loaded LVDTs feature a stainless steel probe assembly and hermetically sealed construction that enables operations in harsh industrial conditions such as exposure to water, sawdust and other debris. The gauge heads also perform over wide operating temperature ranges (-65 °F to 185 °F) with linearity of ±0.15% of full range.
The LVDT gauge heads are designed to provide reliable output for over one million cycles with near-zero drift. Available in measurement ranges of ±0.04" to ±2", the Spring-Loaded Gage Heads are available in a variety of custom options including right-angle connectors, temperature ranges up to 400 °F (200 °C), mild radiation resistance to 30 MRad and pneumatic probes.
NewTek Spring-Loaded LVDTs are offered with AC, DC voltage or 4-20 mA current outputs. The AC-operated LVDT gauge heads are suitable for operation in higher temperatures since the sensor is segregated from the electronic circuitry. When paired with a NewTek NTC-6000 LVDT Signal Conditioner, the AC-operated LVDTs deliver position feedback in 4-20mA, 0-5V, 0-10V or RS-485 formats for process control systems requiring digital output.
DC-operated LVDT gauge heads are designed for operation in less hostile environments since they eliminate the installation and cost of signal conditioning equipment. With electronics built into the assembly, the sensor simplifies mechanical set-up into automated machinery.
