FISHER定位器i2P-100产品介绍
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, EPAHQQAR20100505).
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电动气动传感器使用转换器模块，该转换器模块将毫安输入转换为比例压力输出。电流输入范围和压力输出范围均可在现场由用户配置。转换器模块使用最小质量的小零件，这些零件围绕质量中心的枢轴点对称平衡。这种平衡的布置导致了高性能的仪器，降低了对振动的敏感性。
集成的气动继电器可提供驱动气动控制阀/执行器组件所需的高容量，而无需额外的增压器或定位器。当传感器的输出传输到小体积的腔室（例如气动定位器或其他气动仪器）时，该传感器还可以提供稳定，准确的操作。降低的振动敏感性，加上高容量和一阶滞后特性，使i2P-100传感器适合直接安装在控制阀/执行器组合上。
特征
允许与天然气一起使用-i2P-100被批准与天然气一起用作气动供应。
气动耗气量低-变送器的气动耗气量低，从而降低了运营成本。最大稳态消耗量小于美国环境保护局为石油和天然气行业设定的6 SCFH要求（新源性能标准子部分OOOO，EPAHQQAR20100505）。
单一密封设备— i2P-100已根据ANSI / ISA标准12.27.01（电气系统与易燃或可燃过程流体之间的过程密封要求）进行测试，作为单一密封设备。
高输出能力和可调范围—传感器的整体输出继电器体积足以驱动阀门/执行器组合，而无需定位器或体积增强器。可选的用户现场可配置拨码开关设置，输出范围为0.14至2.3 bar（2至33 psi）。
分割范围-使用标准输入信号的一半，可选择用户现场配置的双向分割范围。
耐腐蚀—分开的外壳将电子设备与气动过程隔离开来。电子模块装在坚固的塑料外壳中，有助于防止损坏电子模块。印刷线路板和DIP开关都经过保形涂层处理，有助于防止腐蚀。换流器模块线圈具有耐腐蚀涂层，所有挠性件均镀金，以提供免受恶劣环境的保护。
耐脏供应介质-自由流动的先导级设计和较大的内部空气通道可通过减少污染物积聚和腐蚀的影响而对较脏的气动供应提供出色的耐受性。可拆卸的主节流孔和可更换的5微米过滤器易于拆卸，以进行维护和保养。
