Description

PK200-A73 电流-气动(I/P)转换器

PK200电流-气动(I/P)转换器提供了一种低成本的方法，将毫安输入(4-20或10-50mA模拟信号)转换为比例气动(气压)输出。该装置设计用于广泛的过程控制应用，包括那些具有气动执行设备的应用。PK200内置不锈钢输入/输出仪表。可靠的PK200执行电子反馈控制，同时保持精度的±0.5%的跨度和线性度的±0.2%的跨度。考虑到节能，PK200仅消耗4正常升/分钟(4 NL/分钟)空气，同时提供110 NL/分钟的输出空气容量。PK200补充了横河现有的北美客户质量解决方案系列:压力和温度变送器，流量计，在线分析仪，记录仪，数字回路控制器和整个家族的分布式控制系统。

PK200-A73

PK200-A73 电流-气动(I/P)转换器

The PK200 current-to-pneumatic (I/P) converter offers a low-cost method to convert a milliamp input (4-20 or 10-50mA analog signals) to a proportional pneumatic (air pressure) output. The unit is designed for a broad range of process control applications, including those that feature pneumatic actuating equipment. The PK200 features built-in stainless steel input/output gauges. The reliable PK200 performs electronic feedback control while maintaining accuracy of ±0.5 percent of span and linearity of ±0.2 percent of span. Built with energy savings in mind, the PK200 consumes only 4 normal liters/minute (4 NL/min) air while providing output air capacity of 110 NL/min. PK200 complements Yokogawa’s existing line of Quality Solutions for its North American customers: pressure and temperature transmitters, flowmeters, on-line analyzers, recorders, digital loop controllers and an entire family of distributed control systems.

Features
-Highly accurate signal conversion with minimum effects from process environments
Stainless steel bracket, epoxy coating, and other optional specifications allow the PK200 to be used in a variety of applications.
