Product Overview
The Schubert & Salzer 8049-Ex is a high-precision electro-pneumatic positioner engineered for demanding process control environments. This intrinsically safe (Ex-rated) instrument is designed to accurately position pneumatic control valves, actuators, and final control elements in response to a standard electrical input signal. By continuously comparing the setpoint signal against the actual valve stem position via a mechanical feedback linkage, the 8049-Ex modulates its pneumatic output to eliminate deviation, ensuring precise throttling control. Its robust, explosion-protected housing makes it the ideal choice for hazardous area applications in chemical, petrochemical, and pharmaceutical processing where reliable valve positioning is critical to plant safety and product quality.
