Digital pneumatic positioners safeguards productivity
This company’s specialist actuation brand, IMI STI, has recently developed a high-capacity and high-precision digital pneumatic positioner. The Smart High-Performance (SHP) positioner (photo), which supersedes the existing FasTrak (FT) positioner, uses a control-algorithm system and patented logic to ensure very low stroking times with high dynamic control, mitigating issues from all applications. The solution’s unique design also provides dynamic, high-speed performance in large-volume actuators, minimizing the need for accompanying flow-amplification devices. It also features a vibration-resistant, contactless feedback sensor, providing high-quality, valuable information detailing valve performance. — IMI Critical Engineering, Birmingham, U.K.
