the portion of the M.S that senses or responds directly to the variable being measured

Stage of MS that receives and modifies the signal to a desired magnitude and for reading/storage

Stage of MS that indicates and records the measured value

Stage of MS that interprets the measured signal and exerts control over the process

rate of change of a variable relative to a change in another variable

FSO input range is defined from xmin to xmax

FSO output range is defined from ymin to ymax

an estimate of probable error in a reported value

Smallest detectible change in measured value (smallest scale increment)

act of applying a known input value to a system to observe the system output value

instrument specification that estimates the expected random uncertainty based on multiple tests of a single unit

random uncertainty estimate based on multiple test performed by different labs on a single unit

Instrument uncertainty is estimated based on the square root of the sums of the squares of all individual uncertainties

an extraneous effect that imposes random variations on the measured signal

extraneous effect that imposes a deterministic trend on the measured signal

=factor from diagram * Fn

permits frequencies below the cutoff frequency and attenuates signals with higher frequencies than the cutoff frequency

permits frequencies above cutoff frequency and attenuates signals with smaller frequencies than cutoff frequency

combination of low cutoff frequency and high cutoff frequency to define a band of frequency information permitted to pass through the filter

F/Fc

Fc/F

a constant that may be a positive or negative value, an amplifier for a signal

is used to convert a high impedance charge q into an output voltage E

passive device, does not produce a signal on its own, temperature is a function of resistance. R=rho*l/A

Pair of wires, requires an electronic ice point, J and K types, generates a very small voltage between the pair of wires at temperature differences, voltage can be measured and amplified

measures infrared radiation intensity, requires good calibration to the material and surface, requires line of sight.

relate resistance to a rotational or distance value to measure a quantity, normally distance or to change a voltage output

high sensitivity, low input range, can take 'static' measurements

low sensitivity high input range

measures the current produced by a change in a magnetic field
