Type 2000 T2000 I/P & E/P Transducer

Brand: Marsh Bellofram Group of Companies

The Marsh Bellofram Type 2000 is a robust electronic instrument that regulates an incoming supply pressure down to a precise output pressure which is directly proportional to an electrical control signal.

The secret to the Type 2000’s precise, reliable performance under a variety of demanding environmental conditions is a patented piezoceramic actuator with many industry-wide firsts.
