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 -

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 -

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.
