P200 Pneumatic-to-Current P/I Transducers
Reliable, user-oriented performance


ControlAir's Dahl P200 P/I transducer represents outstanding value in pneumatic to current technology. All solid state circuitry converts standard 3-15, 3-27 or 6-30 psig instrument air into 4-20 or 10-50 mA outputs (4-20 mA only for FM and CSA approval) with uncompromising accuracy and durability. Custom pressure ranges are also available. The P200's explosion-proof housing allows it to stand up to the most hazardous and demanding applications. The P200 is FM approved and CSA certified as NEMA 4 (Enc. 4) for all locations and explosion-proof for Class I, Div. 1, Groups A, B, C, D; dust ignition-proof for Class II, Div. 1, Groups E, F, G; and suitable for Class III, Div. 1 locations.
