Novotechnik U.S. (Southborough, MA) offers the LWX Series of linear position transducers for harsh operating environments, including equipment exposed to high-pressure washdowns, grease, dust and vibration. The corrosion-resistant, all-metal sensors provide direct, absolute displacement measurement in applications such as mobile machine steering cylinders, construction equipment, and industrial machinery.
Movement of a sensor's actuating rod can create pressure changes inside its housing. The LWX Series uses a differential pressure compensation system with a GORE membrane to address this "pump effect." The transducers are rated IP67, including during rod movement, and are available as Model 003 or as Model 004, which features a protective stainless-steel sleeve over the shaft.
A double-bearing actuating rod and low-backlash pivot-head mounting support position measurement where the linkage moves through an angle. The pivot heads permit up to ±12.5° of angular movement. Independent linearity varies by measurement range, reaching ±0.04% on the 750 mm version. The series also offers 0.01 mm repeatability and resolution better than 0.01 mm.
