FISHER定位器i2P-100產(chǎn)品介紹
The Fisher i2P-100 electro-pneumatic transducer, uses a converter module that converts a milliampere input to a proportional pressure output. Both the current input and pressure output range are user-configurable in the field. The converter module uses small parts of minimum mass, which are balanced symmetrically around a pivot point at the center of the mass. This balanced arrangement results in a high performance instrument that reduces sensitivity to vibration.
An integral pneumatic relay provides the high capacity necessary to drive pneumatic control valve/actuator assemblies without additional boosters or positioners. The transducer also provides stable, accurate operation when its output is transmitted to small volume chambers, such as a pneumatic positioner or other pneumatic instrument. Reduced sensitivity to vibration, combined with high capacity and first order lag characteristics, make the i2P-100 transducer suitable for direct mounting on control valve/actuator combinations.
Features
Approved for use with Natural Gas—The i2P-100 is approved for use with natural gas as the pneumatic supply.
Low Pneumatic Supply Consumption—The transducer has low pneumatic supply consumption which lowers operating costs. Maximum steady state consumption is less than the 6 SCFH requirement set for the oil and gas industry by the US Environmental Protection Agency (New Source Performance Standards Subpart OOOO, EPA-HQ-QAR-2010-0505).
Single Sealed Device— The i2P-100 has been tested in accordance with ANSI/ISA Standard 12.27.01 (Requirements for Process Sealing Between Electrical Systems and Flammable or Combustible Process Fluids) as a single sealed device.
High Output Capability and Rangeability— The integral output relay volume of the transducer is adequate to drive valve/actuator combinations without requiring a positioner or volume booster. Selectable user field-configurable dip switch setting for output range of 0.14 to 2.3 bar (2 to 33 psi).
Split Range—Selectable user field-configurable two-way split range, using either half of the standard input signal.
Corrosion Resistant—Separate housing compartments isolate the electronics from the pneumatic process. The electronics module is encased in a rugged plastic shell which helps to prevent damage to the electronics. The printed wiring board and dip switches are conformal coated to help prevent corrosion. Converter module coils have corrosion resistant coating and all flexures are gold plated to provide protection from hostile environments.
Tolerant of Dirty Supply Medium—Free-flow pilot stage design and large internal air passages provide excellent tolerance to dirty pneumatic supply, by reducing the effects of contaminant buildup and erosion. The removable primary orifice and replaceable 5 micrometer filter are easy to remove for service and maintenance.
Fisher i2P-100電動氣動傳感器使用轉(zhuǎn)換器模塊，該轉(zhuǎn)換器模塊將毫安輸入轉(zhuǎn)換為比例壓力輸出。電流輸入范圍和壓力輸出范圍均可在現(xiàn)場由用戶配置。轉(zhuǎn)換器模塊使用最小質(zhì)量的小零件，這些零件圍繞質(zhì)量中心的樞軸點對稱平衡。這種平衡的布置導致了高性能的儀器，降低了對振動的敏感性。
集成的氣動繼電器可提供驅(qū)動氣動控制閥/執(zhí)行器組件所需的高容量，而無需額外的增壓器或定位器。當傳感器的輸出傳輸?shù)叫◇w積的腔室（例如氣動定位器或其他氣動儀器）時，該傳感器還可以提供穩(wěn)定，準確的操作。降低的振動敏感性，加上高容量和一階滯后特性，使i2P-100傳感器適合直接安裝在控制閥/執(zhí)行器組合上。
特征
允許與天然氣一起使用-i2P-100被批準與天然氣一起用作氣動供應。
氣動耗氣量低-變送器的氣動耗氣量低，從而降低了運營成本。最大穩(wěn)態(tài)消耗量小于美國環(huán)境保護局為石油和天然氣行業(yè)設定的6 SCFH要求（新源性能標準子部分OOOO，EPAHQQAR20100505）。
單一密封設備— i2P-100已根據(jù)ANSI / ISA標準12.27.01（電氣系統(tǒng)與易燃或可燃過程流體之間的過程密封要求）進行測試，作為單一密封設備。
