1.0.1

Product

Overview:

The

CC-10

is

a

self-contained,

compact

wide

range

vacuum

gauge

and

controller

employing

the latest

sensor

technology.

The

CC-10

is

able

to

replace

multiple

traditional

gauges

and

provides the

user

with

measurement

capability

from

atmospheric

pressure

to

10

-9

Torr.

The

gauge

requires

22-26

VDC

input

power

and

provides

the

user

with

a

digital

pressure

indication,

analog

output and

RS485

digital

communications.

Three

independent

set

points

can

be

addressed

from

the instrument‟s

control

panel,

from

a

tethered

remote

display

module

or

via

RS485.

1.2

Sensor

Technology:

The

CC-10

uses

two

sensor

types

to

seamlessly

measure

a

pressure

range

of

12

decades.

An crystal

sensor

is

used

to

measure

from

atmospheric

pressure

to

10

-4

Torr

and

a

double

inverted magnetron

cold

cathode

is

used

to

measure

from

10

-2

to

10

-9

Torr.

1.2.1

Crystal

Sensor

Operating

Principle

The

crystal

sensor

is

a

simple

tuning-folk

shaped

quartz

oscillator

that‟s

similar

to

the

oscillators commonly

used

in

wrist

watches.

The

electrical

impedance

of

the

oscillation

depends

upon

the pressure

of

the

gas

that

surrounds

the

quartz

oscillator,

because

the

resistance

to

the

oscillation

(as

caused

by

friction

between

the

quartz

surface

and

gas

molecule),

varies

as

the

pressure changes.

The

crystal

sensor

measures

the

electrical

impedance

of

the

quartz

oscillator

and

its circuitry

converts

it

to

the

pressure

value.

Crystal

Sensor

1.2.2

Cold

Cathode

Operating

Principle

The

double

inverted

magnetron

cold

cathode

sensor

measures

pressure

by

ionizing

the

residual gases

in

a

magnetron

discharge.

The

body

of

the

sensor

serves

as

the

cathode

ands

is

at

ground potential.

The

anode

operates

at

as

much

as

4000

volts.

A

permanent

magnet

traps

electrons

in the

sensor

to

sustain

the

discharge

at

a

very

low

pressure.

This

type

of

sensor;

like

all

ionization sensors,

is

sensitive

to

gas

type,

but

unlike

conventional

ionization

gauges,

has

no

filaments

to burn

out,

can

operate

continuously

at

higher

pressure

and

is

considerably

more

rugged

and reliable.
