The sensors monitor quarter-turn valves and three-way valves, provide continuous 360-degree contactless position measurement and deliver analog or discrete outputs. One includes a stainless steel Minifast connector and the other, using a terminal chamber, provides customers with ATEX and IECEx approvals. Using the inductive resonant circuit measuring principle and introducing an open face sensor design for rotary valve sensing, the units open the door for new potential in valve monitoring on rotary actuators, quarter turn valves and three-way valves, while also detecting the valve position during cleaning cycles. Additionally, the sensors can detecting seal wear, saving downtime from seals that are worn from switching cycles. Featuring a protection rating of IP67 and a compact housing design, the sensors provide a wear-free sensing solution in harsh applications. They operate in temperatures from -25° to +75 °C (EXI version limited to +70 °C), making them suitable for a wide range of applications, including valve automation, steering position feedback and dancer arm control.
