These transducers are an electro-pneumatic device that reduces supply pressure to a regulated output pressure directly proportional to an electrical input signal. These transducers are also field-reversible by reversing the polarity of the signal leads and recalibrating. After calibration, the transducer will then provide a minimum of it''s full rated output pressure upon input signal failure. These units are typically used in HVAC-R systems, petrochemical processing, and slurry processing.
