NewTek Sensor Solutions offers an extended series of spring-loaded LVDTs that provide dimensional feedback for a variety of position measurement and quality assurance applications including go/no-go measurements, automotive part quality testing, roller position/product thickness control, TIR measurements and material testing under stress. Designed with a stainless-steel probe assembly and ¾-in. diameter hermetically-sealed housing, the sensors operate in challenging environments with dirt, water, vibration and temperature ranges of -65° to 220°F while providing highly accurate position measurement with maximum linearity of +0.25% of full-scale output.
The company offers ac/dc operated versions of its gage heads in ranges from ±0.05 in. to ±2 in. (1.27 mm to 50 mm). With electronics built into a spring-loaded assembly, dc-operated units do not require external electronics, reducing installation time and costs. The ac-operated configurations can withstand higher temperatures and provide a variety of analog or digital outputs when connected to an LVDT signal conditioner.
