AutoQuiz: What Are the Four Key Activities in the Maintenance Cycle of a Control System?
Documentation of the "as left" condition of the control system is a basic requirement for all maintenance, calibration, commissioning, and testing tasks. -
AutoQuiz: What Are Multiple Independent Protection Layers in Relation to Industrial Safety?
A consequence of the concept of multiple independent protection suggests minimization of risk occurs when safety instrumented systems are completely independent from process control systems. -
How the IIoT Puts Factory Electrical Systems at Risk and What You Can Do About It
Factories of the future will demand advanced circuit protection technology to keep everything connected. -
AutoQuiz: How to Determine Cause of the Apparent Discrepancy in Flow
Periodic visual inspection of orifice plates is required to ensure the integrity of measurement with a digital flow transmitter. -
AutoQuiz: Which Flowmeter Type Does Not Operate on the Principle That a Differential Pressure Is Developed Across a Flow Restriction?
A Coriolis flowmeter develops a flow measurement by measuring the degree of deformation (twisting) of a vibrating tube(s) as the fluid moves through the tube. -
AutoQuiz: P&ID Determination for Temperature and Pressure Sensors
Instrument technicians often use P&ID diagrams as a reference to identify what type of instrumentation is installed and how the instrumentation is installed in the process. -
The Past and the Future of Industrial Maintenance Management
What started as the sole responsibility of engineers and technicians has now grown to become a backbone of business operations as organizations realize the impact maintenance can have on their efficie -
How HMI Technologies Enable Greater Remote Access to the Plant Floor
Converging networking and other technologies ease remote access from the plant floor to PCs, tablets, and smartphones. -
AutoQuiz: How to Assess the Optimal Alarm Deadband Setting
Learn to assess the alarm deadband setting on a high alarm. -
AutoQuiz: How to Assess the Hazard/Risk Category for an Industrial Electrical Panel
Work on energized electrical conductors and circuit parts, including voltage testing on panelboards, or other equipment rated 240V and below would be classified as Hazard/Risk Category 1. -
AutoQuiz: How is the Reynolds Number Used in Flow Measurement?
For the Reynold's number, the inertial forces in the numerator are given by the product of mass (density), fluid velocity, and pipe diameter. -
![Neural Network-Based Actuator Fault Diagnosis for a Non-Linear Multi-Tank System [Technical]](/documents/d/acom/neural-network-based-actuator-fault-diagnosis-non-linear-multi-tank-system.jpg)
Neural Network-Based Actuator Fault Diagnosis for a Non-Linear Multi-Tank System [Technical]
Appropriate actuator fault estimation allows for the application of various fault tolerant control strategies enabling compensation of the faulty actuator by increasing performance of the other actuat -
How Industry 4.0 and Digitization Improves Manufacturing Responsiveness, Quality, and Efficiency
Automation is essential to the implementation of Industry 4.0 and IoT strategies as manufacturers realize low labor rates are no longer a winning strategy. -
AutoQuiz: Characteristics of a Full-Wave Bridge Rectifier Circuit
A bridge rectifier consists of diodes in a bridge circuit configuration. It features the same output polarity for either input polarity, and is used for converting an alternating current (AC) input in -
AutoQuiz: How to Read a Gauge Pressure Transmitter
At zero gauge pressure in the steam line, you are essentially suppressing (pushing) the transmitter output back down to zero after the system reaches equilibrium. The transmitter will read that impuls -
AutoQuiz: Loop Tuning Terminology for Change in Amplitude
The common method of judging tuning is known as the "quarter wave decay" method. It has been shown if a loop is tuned so the oscillation decays with each wave being one quarter of the previous wave, i -
AutoQuiz: Industrial Applications for Nonincendive-Rated Field Wiring
Nonincendive is allowed in Class 1, Division 2; Class 1, Zone 2, and Non-hazardous rated areas. Use in higher hazard areas, such as Division 1, Zone 1, or Zone 0 areas, is not allowed. -
AutoQuiz: Standard Wiring Color for Type K Thermocouple
Type K (chromel–alumel) is the most common general purpose thermocouple with a sensitivity of approximately 41 µV/°C. -
AutoQuiz: What are the Advantages and Disadvantages of RTDs?
Resistance temperature detectors require a temperature transmitter to function. This is not a disadvantage of an RTD, since its function does not require a temperature transmitter to be installed. -
AutoQuiz: How to Interpret Relay Logic for a Pump Control Switch
When a pump control switch is in auto, the storage tank low level switch or the pressure tank high level switch can stop the pump.
