Bellofram E/P Pressure Transducer 3-15 PSI, 1-9 VDC

The Bellofram 961-085-000 Type 1000 electro-pneumatic E/P transducer converts an electrical input signal to a proportional pressure output. The pneumatic output is both linear and proportional to the analog 1-9 volt DC input command signal. Bellofram's most popular general purpose transducer combines performance, reliability, and value for many precision control applications. Features include a small size, built-in volume booster, external zero & span adjustments, and field reversible operation. All Type 1000 transducers can be mounted inline or use the wall/panel mounting bracket which is included with each unit. The Type 1000 is a force balanced device in which the coil is suspended in the field of a magnet by a flexure. Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves against the end of a nozzle, and creates a back pressure in the nozzle by restricting air flow. The back pressure acts as a pilot pressure to an integral booster relay. Consequently, as the input signal increases (or decreases, for reverse acting), output pressure increases proportionally. Applications include valve actuators & positioners, HVAC systems, clutches & brakes, paper handling, textile processes, and many other industrial applications where precise pneumatic control is required.
