AutoQuiz: When Should Operating Instructions Be Developed for an Industrial Process?
Operating instructions may be included in a functional specification or operating description and may range from a few pages describing how to operate one part of a plant to a complete set of directio -
How ISA’s Certification and Certificate Programs Can Benefit You and Your Employer
ISA certification holders have demonstrated higher levels of technical competence. They earn more than others and have greater employment opportunities. -
AutoQuiz: Cold Junction Compensation Is Required for Which Type of Temperature Measurement Device?
A thermocouple is comprised of two wires of dissimilar metals, connected at one end, which is placed in the process to be measured. This is called the measuring junction. -
AutoQuiz: What Security Property Is Affected If a Hacker Intercepts and Changes Set Point Data?
Data integrity implies that the data received is the same (value, format, quality) as the data sent. -
AutoQuiz: What Is a Schematic Representation of a Complete Hydraulic, Electric, Magnetic, or Pneumatic Circuit Called?
A loop diagram shows complete details of a hydraulic, electric, magnetic, or pneumatic circuit, showing all of the interconnections, components, and devices that participate in that circuit. -
AutoQuiz: What Is the Fastest "Electronic" Method to Bring a DC Motor to a Full Stop?
In regenerative braking, all of the motor's energy is fed directly back into the AC power line. -
AutoQuiz: Unique Feature of a Pneumatic Differential Pressure Sensor/Transmitter
In a pneumatic transmitter, the nozzle faces a baffle, so, as the measured pressure increases, the baffle moves toward the nozzle. -
AutoQuiz: What Is the Definition of Restore Time in Industrial Maintenance?
The restore time includes all activities required to diagnose and repair the device. This includes diagnosing the problem, isolating the device from the system, traveling to the device, and repairing -
AutoQuiz: What Is the Condition When Controller Output Increases in Conjunction With a Controlled Variable Increase?
As pressure increases (controlled variable), the valve output would increase to open the valve in order to relieve the pressure. -
AutoQuiz: How to Program the Correct PLC Equation for a Pressure Transmitter
To scale the analog input, calculate the "% of the raw counts range" that is represented by the analog input, and multiply by the EU100% range, since the EU0% value is 0. -
AutoQuiz: How to Perform PLC Raw Count Calculations for Pressure Transmitters
A pressure transmitter is connected to the analog input card of a PLC. The 4-20mA input value from the transmitter is converted into equivalent raw counts. -
AutoQuiz: What Is the Purpose of an Optical Isolation Circuit on a Digital Input Card in a PLC I/O System?
An optical isolation circuit is used to provide a barrier between the field wiring & associated field wiring issues (shorts, ground loops, transients, etc.) -
