In the modern world, a reliable, efficient and cost-effective instrumentation and control system is an essential tool for any successful business or project.
Unfortunately, with the sheer number of electronic components and instruments available, it can be confusing, and difficult to understand, when attempting to create the correct instrumentation and control system. This is why having a comprehensive and up-to-date Instrumentation and Control Installation Manual is so important.
The purpose of the Instrumentation and Control Installation Manual is to help reduce the amount of time needed to successfully install the correct system, by providing a comprehensive list of descriptive terms, illustrated drawings, diagrams and other material which can be used as reference during design and implementation.
In this guide, we will provide a list of the most common instrumentation and control installation terms, along with a brief description of each. This includes both English and Chinese terms.
Instrument
Instrumentation 仪器
An instrument is a device used to observe, measure or control the physical or chemical properties of a system.
Instrument Control Panel 仪器控制面板
A control panel is used to monitor and control the processes used by a system, such as a pump or a compressor.
Signal 信号
A signal is a means of communication, often used as an alert or prompt to adjust an instrument.
Controller 控制器
A controller is an electronic device used to achieve an output that matches a desired input.
Sensor 传感器
A sensor is a device used to measure and detect physical or chemical changes in the environment.
Actuator 执行器
An actuator is an electronic device used to physically move a part of a system, such as a valve or a motor.
Transducer 变送器
A transducer is an electronic device used to convert electrical signals into physical ones.
Amplifier 放大器
An amplifier is a device used to increase the strength of an electrical signal.
Analog 模拟
An analog signal is generated by a continuous waveform, rather than a discrete one.
Digital 数字
A digital signal is produced by a discrete waveform, rather than a continuous one.
Manometer 测压表
A manometer is a device used to measure the pressure of a fluid.
Calibration 校准
Calibration is the process of adjusting instruments to accurately measure a particular variable.
Dead Band 死区
A dead band is the range of variable input which will not cause a change in the device’s output.
Feedback 反馈
Feedback is the process of monitoring and adjusting a system based on the response received from a sensor or controller.
Alarm 报警
An alarm is a device that warns the user of abnormal conditions.
Modulation 调制
Modulation is the process of changing a signal, such as for data transmission.
Switch 开关
A switch is a mechanical device used to control the flow of electricity.
Indicator 指示器
An indicator is a device used to display a value or signal.
Timing 定时
Timing is the process of controlling the timing of activities within a system.
Multiplexer 复用器
A multiplexer is a device used to transmit multiple signals over a single line.
Communication 通讯
Communication is the exchange of data between systems.
Encoder 编码器
An encoder is a device used to convert signals into a digital format.
Programmer 程序员
A programmer is a person who writes, tests and debugs computer code.
Testing 测试
Testing is the process of examining instruments and equipment to ensure they are functioning properly.
Validation 确认
Validation is the process of verifying that an instrument or system is accurate, reliable, and-high quality.
Interface 接口
An interface is a device used to connect different components of an instrumentation and control system.
Optimization 优化
Optimization is the process of operating a system in the most efficient manner.
Integration 集成
Integration is the process of connecting different parts of an instrumentation and control system to form a functioning whole.
Utilization 使用
Utilization is the process of using a system to its fullest potential.
