Macro Sensors’ HSTAR 750 Series hermetically sealed position sensors offer accuracy and long life in applications such as the position measurement of steam control valves in power generation plants. Constructed from stainless steel, these 19mm diameter ac-operated position sensors tolerate high temperatures (up to 400°F).
Along with its resistance to high temperatures, the HSTAR 750 units feature high resolution, excellent repeatability and low hysteresis as well as high sensitivity consistent with good linearity. This means operators don’t need to change out units frequently and can rely on output to maintain optimum plant operations.
Electrical termination of the HSTAR 750 Series also is made through a sealed radial connector located near one end. The radial connector results in a through-bore design that permits access to either or both ends of the unit’s core for better mechanical support and core guidance, and easier cleanout in dusty or dirty locations. As the radial connector has a shorter installed length, the length of the HSTAR 750 Series sensors are at least 2” shorter than comparable units with an axially mounted connector for easier installation in tight spaces.
Available in ranges of ±0.050 inch (±1.25 mm) to ±10.0 inches (±250 mm), HSTAR 750 sensors are offered in several standard options including metric threaded cores, smaller diameters and low mass cores.
