I to P Transducer Type 1000



The Marsh Bellofram Type 1000 is an electro-pneumatic transducer that reduces a supply pressure to a regulated output pressure directly proportional to a converted electrical input signal. The Type 1000 accepts a wide range of supply pressures, ranging from a minimum of 3 psig (0.2 BAR) above the maximum output up to 100 psig (6.9 BAR). An integral pneumatic volume booster provides high flow capacity (up to 12 SCFM/339 slpm). Model selections include general purpose, NEMA 4X Type, extended range, high relief, intrinsically safe, and explosion proof. The 4-20 mA input, 3-15 PSIG output model can be recalibrated to provide 3-9 PSIG or 9-15 PSIG output for split ranging applications.

I to P Transducer Type 2000

 

The Marsh Bellofram Type 2000 is a highly robust E/P transducer with typical full-scale accuracy of 0.1%, designed to provide precise electronic pressure control of humid (non-condensing) and oil-laden process gases within harsh industrial environments.

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 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 for added durability. The uniquely rugged construction of the Type 2000 facilitates exceptional performance and longevity, making it ideal for use within corrosive environments. This design also eliminates many of the performance issues seen in other industry piezoceramic pressure transducers, such as electronic range of authority, arcing, silver electrode migration, electrode micro cracking, de-poling, and low voltage-to-work density.

Features:

  • ±0.1% of full-scale output typical (0.25% guaranteed); includes effects of hysteresis, dead band, and repeatability

  • Patented, Hermetically Sealed Piezoceramic Dimorph and Isolated Electronics

  • Available Pressures to 120 PSIG (Zero Based)

  • High Immunity to EMI/RFI

  • Insensitivity to Extreme Temperature and Supply Pressure Fluctuations

  • Insensitivity to Extreme Vibration and Orientation

  • NEMA 4X, CE, and FM and ATEX (Intrinsically Safe) Approved Versions (S Model)

  • Explosion-proof and Dust-ignition Proof Versions (EX Model)

Applications:

• Refineries

• Petrochemical Industry

 

I to P Transducer Type 5000

The Type 5000 is a compact, rugged and reliable two-wire pressure transmitter, expressly designed for industrial field service. This precision unit converts a signal pressure input into a precise 4-20 mA or 10-50 mA output. The lightweight housing includes a 1/4 NPT pressure port and 1/2 NPT conduit port for field wiring. Connections are easily accessible via top cover removal. Zero and span adjustments are available within the field wiring compartment for fine, on-site calibration adjustment. The Type 5000 pressure transmitter uses a unique, temperature compensated piezoresistive transducer, suitable for gauge pressure measurement of non-corrosive liquids and gases. The sensor has excellent dynamic response and is virtually insensitive to mounting orientation and ordinary industrial vibration. Mounting holes on the transmitter housing are arranged to permit direct pipe (2″) mounting for minimum installed cost.

Features:

  • 0.1% Accuracy Typical

  • Piezoresistive Pressure Transducer Resists Vibration

  • Mounts at Any Angle

  • Easily Accessible Zero and Span Adjustments

  • NEMA 4X Housing Approved for Explosion-proof Service
