FOXBORO 43AP-FA42C/PB-AA 气动指示调节器是一款功能丰富的过程控制仪表，以下是对其的详细介绍：

一、品牌与制造商

品牌：FOXBORO（现为法国Schneider电气旗下品牌）
制造商：Schneider Electric（施耐德电气），成立于1836年，是世界能源管理公司、优化解决方案供应商之一，主要产品包括断路器、传感器、控制器等，为各国能源设施、工业、数据中心及网络、楼宇提供整体解决方案。

二、产品特点

多功能性：Foxboro 43AP系列气动指示调节器几乎适用于任何工艺，可用于控制压力、温度、流量和液位。
高精度：该调节器具有高精度，输入指针的精度为合格元素的±0.5%跨度，重复性为跨度的0.2%，死区为跨度的0.1%。
多种操作模式：提供开关、比例、比例加导数、比例加积分(复位)、比例加积分加导数、微分间隙和自动关机操作等多种操作模式。
可靠性：控制单元和测量元件都安装在刚性钢板上，不受安装应力的影响，确保了可靠的精度。断电和供气压力损失不会影响过程驱动指示。
环境适应性：玻璃纤维加固的外壳和带聚碳酸酯防碎窗的密封门符合IEC IP53标准，提供NEMA® 类型3的环境保护。

三、技术规格

输出信号：如所指出的，可以是20至100kPa、3至15psi、或0.2至1.0bar/kg/cm²。
耗气量：在标准条件下为0.5 m³/h（0.3 cfm）。
环境温度影响：在正常工作条件下，每55°C（100°F）变化在中跨处的大控制点位移为输入范围的1%。
供应压力影响：在正常操作条件下，每7 kPa（1 psi）变化在中跨处的大控制点位移为输入跨度的0.2%。
重量：近似质量为4.8千克（10.6磅），不包括元素。

四、安装与操作

安装方式：可安装在面板上、平面上或内部无缓冲自动手动转换站上。
操作简便：内部无缓冲自动-手动转换站允许在自动控制和手动控制之间进行无缓冲平衡转换，避免意外转送。

FOXBORO 43AP-FA42C/PB-AA pneumatic indicating regulator is a feature-rich process control instrument. The following is a detailed introduction to it:

1. Brand and manufacturer

Brand: FOXBORO (now a brand of Schneider Electric of France)

Manufacturer: Schneider Electric, founded in 1836, is one of the world's energy management companies and optimization solution providers. Its main products include circuit breakers, sensors, controllers, etc., providing overall solutions for energy facilities, industries, data centers, networks, and buildings in various countries.

2. Product features

Versatility: Foxboro 43AP series pneumatic indicating regulators are suitable for almost any process and can be used to control pressure, temperature, flow and liquid level.

High precision: The regulator has high precision, the accuracy of the input pointer is ±0.5% of the span of the qualified element, the repeatability is 0.2% of the span, and the dead zone is 0.1% of the span.

Multiple operating modes: Multiple operating modes are available, including switch, proportional, proportional plus derivative, proportional plus integral (reset), proportional plus integral plus derivative, differential gap, and automatic shutdown operation.

Reliability: The control unit and measuring element are mounted on a rigid steel plate, which is not affected by mounting stress, ensuring reliable accuracy. Power failure and loss of air supply pressure will not affect the process drive indication.

Environmental adaptability: The fiberglass reinforced housing and sealed door with polycarbonate shatterproof window meet IEC IP53 standards and provide NEMA® Type 3 environmental protection.

III. Technical Specifications

Output signal: As indicated, it can be 20 to 100 kPa, 3 to 15 psi, or 0.2 to 1.0 bar/kg/cm².

Air consumption: 0.5 m³/h (0.3 cfm) under standard conditions.

Ambient temperature effect: Under normal operating conditions, the maximum control point displacement at mid-span is 1% of the input range for every 55°C (100°F) change.

Supply pressure effect: Under normal operating conditions, the maximum control point displacement at mid-span is 0.2% of the input span for every 7 kPa (1 psi) change.

Weight: Approximate mass is 4.8 kg (10.6 lbs), excluding elements.

IV. Installation and operation

Installation: Can be mounted on a panel, on a flat surface, or on an internal unbuffered automatic-manual transfer station.

Easy operation: The internal unbuffered automatic-manual transfer station allows unbuffered balanced conversion between automatic and manual control to avoid accidental transfer.

V. Application areas

Foxboro 43AP-FA42C/PB-AA pneumatic indicating regulators are widely used in industrial automation, especially in applications where precise control of pressure, temperature, flow and level is required, such as energy, infrastructure, industrial process control, building automation and other fields.
