What is a fluid?

Front

A substance that can or will flow (liquid, gas-vapor, solids). Example: -Gasoline - liquid -Steam - gas -Talc powder - solid

Back

Give four examples of pressure sensors

Front

Manometer Bourdon tube Diaphragm Bellows

Back

What is pressure?

Front

Force per unit area (P=F/A).

Back

What are variables?

Front

Variables are physical devices or states that are: - Controlled - Measured -Manipulated Ex.: Pressure, level, flow, temperature and density

Back

What is instrumentation?

Front

Is the science and art of measurement, control and process manipulation

Back

Range

Front

Calibration range is the upper and lower values that the instrument is capable of measuring.

Back

One atmosphere of pressure is defined as:

Front

14.7 psi - 101.3 Kpa - 1 Bar

Back

A reference number that compares the weight of a specific volume of liquid to the same volume of water is called the?

Front

Specific gravity

Back

What is "Measurement"

Front

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.

Back

What is applied to the threads of a fitting prior to attaching it to an instrument?

Front

Teflon tape

Back

Instrumentation does what?

Front

This technology creates, constructs, and maintains the measuring and control devices and systems to allow process plants to optimize their production.

Back

Accuracy

Front

is the ratio of the error to the full score output expressed in percent span or percent reading.

Back

Spam

Front

is define as the algebraic difference between the upper and lower range values

Back

Tolerance

Front

is the permissible deviation from a specific value.

Back

Transducer

Front

A device that converts energy from one form to another. This conversion may be pressure to movement, electric current to pressure, liquid level to a twisting movement on a shaft, or any number of other combinations.

Back

What is a "measurand"

Front

A quantity intended to be measured An object being measured A physical quantity or property being measured So the diameter of the cylinder shaft in its midsection is the measurand in example a. The proportion of chromium in the rolled steel sheet is the measurand for example b. The measurand in example c is the specific weight of silver.

Back

What is the mathematical expression of pressure?

Front

P= F/A

Back

Name three instruments that are used by environment Canada to determine the weather.

Front

Barometer Anemometer Thermometer Ruler Rain gauge Wind sock Doppler radar

Back

Given an example of process loop in your home?

Front

The control of temperature inside your house.

Back

How process loops identified?

Front

Often process loops are colour code: Pressure: blue Level: green Flow: red Temperature: yellow

Back

Zero

Front

is the lower end of the scale

Back

What is a Datum Point

Front

It is a point which serves as a reference or base for the measurement of other quantities.

Back

RESOLUTION

Front

Resolution is defined as the smallest change that can be detected by a sensor

Back

Pressure Units

Front

Pounds per square inch (psi) or N/m2 - Pascal (Pa or kPa)

Back
