Pneumatic-to-Current P/I Transducers

P/I transducer is field-mounted, explosion-proof, rack mountable and CSA & FM approved.

Categories: ,

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 explosion-proof housing allows it to stand up to the most hazardous and demanding applications.
