Bellofram 966-753-000 Type 1500 NEMA 4X electro-pneumatic I/P transducer with FM/CSA approvals convert an electrical input signal to a proportional pressure output. The pneumatic output is both linear and proportional to the analog 0-10 VDC input command signal. Standard features include, small compact size, built-in volume booster, external zero & span adjustments, field reversible, low cost. All Type 1500 transducers have CE certification, can be mounted at any angle, and offer high vibration resistance. The Type 1500 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.
