According to IEC 61511-1, embedded software, which is part of the safety device/ controller, should follow software guidelines in IEC 61508-3. -
FeatureAutoQuiz: How to Calculate the Inherent Flow Characteristic of a Valve
The inherent flow characteristic is the relationship between valve capacity and valve travel, and it is usually expressed graphically. -
FeatureAutoQuiz: Industrial Electrical Standards for Emergency Operations
The reset of an emergency stop circuit will not initiate a restart. -
FeatureAutoQuiz: What Are the Characteristics of a Piston Actuator?
An actuator is a device that applies the force necessary to cause a valve's closure member to move. -
FeatureAutoQuiz: What Is the Length Limitation for Fast Ethernet Cable?
Because of the high speed of fast Ethernet, the use of twisted pair cable is limited to 100 meters (330 feet). -
FeatureAutoQuiz: How Is Fluid Velocity Affected When the Pressure Drop Across a Valve Increases?
The pressure drop refers to the change or drop in pressure from the upstream side of the valve to the downstream side. -
FeatureAutoQuiz: What Is the Most Appropriate Technique for Modeling Linear Relationships?
The multivariate statistical-process control excels at modeling unknown linear relationships for a large number of inputs that could be correlated. -
FeatureAutoQuiz: What is the Inherent Flow Characteristic of a Valve?
The "inherent flow characteristic" is the relationship between valve capacity and valve travel, and it is usually expressed graphically. -
FeatureAutoQuiz: How to Minimize the Effect of Feed Upsets to the Top of a Distillation Column
A distillation tower has feed upsets that are measured and used to create a feed forward signal. -
FeatureAutoQuiz: How to Install an Electromagnetic Flowmeter
The magnetic flowmeter conductor (fluid in pipe) moves through a magnetic field; a voltage is produced relative to speed of the conductor & magnetic field. -
FeatureAutoQuiz: How to Calculate the Transfer Function
A transfer function is a mathematical representation of the relationship between the input and output of a system. -
FeatureAutoQuiz: Which Orifice Plate Is Used to Eliminate Damming of Material at the Top or Bottom of a Pipe?
Orifice plates are in a straight run of smooth pipe away from valves and fittings so they do not interfere with the restrictor and readings. -
FeatureAutoQuiz: Which Fuse Has the Quickest Response to Over Currents?
Certain types of fuses have a very high speed of response to over currents. They provide excellent short-circuit component protection. -
FeatureAutoQuiz: Optimal Beveled Orifice Angle for Flow
An orifice plate inserted in the line causes an increase in flow velocity and a corresponding decrease in pressure. -
FeatureAutoQuiz: What Is the Maximum Level of Precision Available Using Modbus?
To achieve more precision special programming or a specialized version of Modus is necessary. -
FeatureAutoQuiz: What is the Most Common Pressure Tap?
The purpose of pressure taps is prevent gas or vapor accumulations in the connections between the pipe and differential-pressure (dP) measuring device. -
FeatureAutoQuiz: Standard NFPA Wire Colors
NFPA's mission is to reduce fire and other hazards via scientifically based consensus codes and standards, research, training, and education. -
FeatureAutoQuiz: Characteristics of a Control Valve
A rotary valve has a flow closure member that rotates in the flow stream to modify the amount of fluid passing through the valve. -
FeatureAutoQuiz: What Type of Electrical Enclosure Resists Corrosion and Provides Protection?
NEC 2002 defines an enclosure Type 4x as ideal for outdoor use and resistant to splashing water, windblown dust, hose directed water, and corrosion. -
FeatureAutoQuiz: What is the Coriolis Effect?
Using the Coriolis effect that causes a laterally vibrating tube to distort, a direct measurement of mass flow is obtainable using a Coriolis flowmeter. -
FeatureAutoQuiz: What Flowmeter Does Not Use an Obstruction?
A magnetic flowmeter is a volumetric flowmeter, which does not have any moving parts and is ideal for wastewater applications or any dirty liquid. -
FeatureAutoQuiz: Best Strategy for Finding Efficient Operating Points with Complex Shifting Process Conditions
Real-time optimization with a detailed process model is the best approach to fining the most efficient operating points. -
FeatureAutoQuiz: What Is the Application for an Impulse Line in Fluid Flow?
Impulse lines connect the process to the pressure transmitter, to reduce the effect of ambient temperature on the transmitter's operability and life span. -
FeatureAutoQuiz: Why Are Gathering Requirements Critical to the Success of an Automation Project?
Gathering requirements are important because they define the objectives, purpose, scope, needs, and other key meters. -
FeatureAutoQuiz: What Is the Process for a Continuity Check of a Field Transmitter?
A continuity check is performed on a length of finished wire or cable to determine if the electrical current flows continuously throughout the length. -
FeatureAutoQuiz: How to Measure and Compensate for Disturbances to Prevent Set Point Deviance
The objective of feedforward control is to measure disturbances and compensate for them before the controlled variable deviates from set point. -
FeatureAutoQuiz: What Is the Dead Band of an Instrument?
The dead band is the range through which an input signal may vary, upon reversal of direction, without initiating an observable change in output signal. -
