500

• This term is used to identify the process by which a measurement standard is applied to an instrument for the purpose of adjusting the instrument to match the standard.

Calibration

Terms 2

100

• This term is used to identify the function performed in a smart instrument where the user desired measurement ranges are entered.

reranging

200

• This term is used to identify the procedure where an input standard is applied to the transmitter to adjust how the transmitter reads a measurement signal.

Sensor trim

300

• This term is used to identify the procedure where an output standard is connected to a transmitter to adjust the accuracy of the transmitter’s output signal.

400

• This is a device that is used on the sensor side of a transmitter during calibration.

Input Standard

500

• This is a device that is used on the output side of a transmitter during calibration.

Output Standard

Terms 3

100

• What is the term used to identify the value represented by the deviation of a measurement from the desired value?

error

200

• What are the four components of a feedback control loop?

Sensor, transmitter, controller, final control element

300

• What does PID stand for in “PID Control”?

Proportional, integral, derivative

400

Which two level measurement technologies utilize time-of-flight to determine level?

Radar

Ultrasonic

500

Which level technology utilizes a source and a container as components when measuring level?

Gamma, radiometric, radiation

Terms 4

100

Which level technology utilizes the tank wall and the process fluid as a conductor to infer level?

Capacitance or Conductive

200

List the four most common stop valves.

Butterfly, globe, ball, gate

300

Which valve type is designed to allow flow in only one direction?

Check Valve

400

Which stop valve type(s) have a stem?

Gate, globe

500

What keeps the process media from leaking past the stem of a globe valve?

Packing, packing nut

Terms 5

100

List the rotatory type stop valves.

Butterfly, ball

200

List two types of valve operators.

Hand wheel, electro-pneumatic positioner, solenoid,....

300

• This flowmeter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid‘s inertia.

Coriolis

400

• In this type flowmeter, as soon as the electrically charged particles of a fluid cross the artificial magnetic field generated by two field coils, an electric voltage is induced. This voltage, tapped by two measuring electrodes, is directly proportional to the velocity of flow and thus to the flow volume.

Magnetic

500

• In this flowmeter type, ss soon as the fluid in the tube starts to flow, the signals are accelerated in the direction of flow but delayed in the opposite direction. The differential transit time, measured by the two sensors, is directly proportional to the flow rate.
