Now there’s a compact I/P transducer that delivers reliable high performance for the toughest applications in the most hazardous environments: the Type 950XP from ControlAir. The Type 950XP converts an electrical current signal to a stable, pneumatic output to actuate valves. Its NEMA 4X (IP65) housing is designed for both Intrinsically Safe* and Explosion-Proof* operation. Advanced circuitry includes electronic feedback control for superior vibration protection and highly accurate output.
With flow rates up to 12 SCFM (340 Nl/min), the Type 950XP has the muscle to drive large valves and actuators. Yet because it typically consumes only 0.05 scfm (0.11 m3/hr) at mid range, it not only costs less to buy, it costs less to operate as well. And because it takes impure air in stride, downtime is reduced, too.
The Type 950XP gives you big flexibility. Its small footprint can fit into tight spots. Its standard mounting bracket lets you mount it directly on a valve, wall, panel, or pipe. Optional, field-selectable process output ranges reduce downtime and inventory. And since the Type 950XP is position insensitive, it gives you even more freedom in mounting and connecting to valves and instruments. As a result of this flexibility, installation goes faster. Easy access Zero and Span adjustments make bench or field calibration quick and easy. For operating versatility, you may choose direct, reverse, and split range modes.
