TE Connectivity Macro Sensors’ PR 750 Series of 3/4 inch (19 mm) diameter AC-Operated LVDTs are general purpose contactless linear position sensors for both OEM applications and end user requirements. They are available in full scale measuring ranges from ±0.050 inch (±1.25 mm) to ±10 inches (±250 mm) and offer a core-to-bore radial clearance of 0.031 inches (0.25 mm) with the standard core supplied. PR 750 Series sensors feature the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, as well as the highest sensitivity consistent with good linearity. The maximum linearity error for any of these sensors is ±0.25% of full range output, using a statistically best-fit straight line derived by the least squares method.
The proven reliability of PR Series LVDTs is a direct result of manufacturing processes and assembly techniques developed and optimized by Macro Sensors personnel over many years of making LVDTs. Their environmental robustness stems from the materials of their construction, such as glass-filled polymer coil forms for thermal stability and stainless steel housings that act as magnetic shields to reduce the effects of any external AC magnetic fields. Their external sealing meets IEC standard IP-61.
