Electro-pneumatic transducer
Marsh Bellofram
With a unique design that incorporates a patented, hermetically sealed piezoceramic Dimorph and isolated electronics, the Type 2000 pressure transducer regulates an incoming supply pressure down to a precise output that is directly proportional to an electrical control signal, with available pressure ranges (zero-based) to 120 PSIG. In addition, the Type 2000 features a top-mount cover, which provides access to field-configurable inputs and outputs, direct/reverse acting/ranging, which allows the transducer to regulate to maximum output at minimum input; and split/full ranging capabilities. Units also feature IP66 environmental sealing.
The rugged construction of the Type 2000 facilitates exceptional performance and longevity, making it ideal for corrosive environments, while exhibiting high immunity to both EMI/RFI and insensitivity to extreme temperature and supply pressure fluctuations and extreme vibration and orientation. This design eliminates the performance issues seen in other piezoceramic pressure transducers, such as electronic range of authority, arcing, silver electrode migration, electrode micro cracking, de-poling, and low voltage to work density. Type 2000 is offered with NEMA 4X, CE, and FM and ATEX industry approvals. Explosion-proof and dust-ignition proof versions are also available.
