AutoQuiz: What is Tree Topology in Fieldbus?
Tree Topology concentrates the connection of several field devices to couplers/junction boxes. Tree topology is also known as "Chickenfoot" or "Star" configuration. -
Feature
AutoQuiz: What P&ID Symbol Is Used to Indicate a Temperature Regulator?
The symbol reflects a temperature regulator, filled thermal system. -
Feature
AutoQuiz: How to Assess the Optimal Alarm Deadband Setting
Learn to assess the alarm deadband setting on a high alarm. -
Feature
AutoQuiz: What Is the Purpose of an Intrinsic Safety Barrier?
An intrinsic safety barrier prevents excess voltage and current from reaching the hazardous area. -
Feature
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. -
Feature
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. -
Feature
AutoQuiz: What Is the Best Tuning Method for a Catalyst Feed Flow Controller?
Only a closed-loop tuning method can be used with an exothermic reaction where the reactor can "run away" (increasing speed of reaction as the reaction progresses, catalyzed by its own heat of reactio -
Feature
AutoQuiz: Plotting Control Valve Characteristics
For an equal percentage valve characteristic, each increment of valve movement provides the same percentage increase in flow. -
Feature
AutoQuiz: What is the Lifecycle Economic Model?
All lifecycle costs should be considered over the entire expected life of a project, with all costs calculated on a net present value basis. -
Feature
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 -
Feature
AutoQuiz: What Is the Cause of Cavitation in a Liquid Flow Stream?
When fluid drops below a liquid's vapor pressure, a gas is formed. As fluid moves downstream to where the fluid pressure is greater than the vapor pressure, it "collapses" back into a liquid. -
Feature
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 -
Feature
AutoQuiz: Failures of Complex Systems in SIS Design and SIL Selection
A fault tree analysis begins with the "top event," which is the result of a number of basic events that contribute to, or initiate, the system failure. -
Feature
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 -
Feature
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. -
Feature
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. -
Feature
AutoQuiz: What Is the Liquid Flow Condition Where Falling Static Pressure Causes Formation of Vapor Bubbles?
The first stage of cavitation is the formation of vapor bubbles within the liquid system because of the fluid's static pressure falling below the fluid vapor pressure -
Feature
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. -
Feature
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. -
Feature
AutoQuiz: How to Diagnose Industrial Pressure Sensor Errors
If a pressure sensor/transmitter is giving a non-linear response, replacement of the sensor and/or the transmitter will be required.
