Pressure, Vacuum & Compound Gauges
Pressure
& Vacuum Gauges:
Pressure gauges
and vacuum gauges
are very commonly
used instruments
for measurement
of pressure in
process in almost
all type of industries.
We have bourdon
type Pressure
Gauges; Diaphragm
sealed pressure
gauges, Shaffer’s
Diaphragm Gauges,
Electrical Contact
type Gauges, Master
Gauges, Test gauges,
Remote Sealed
gauges etc. All
these gauges are
advised for specific
application.
In Pressure &
Vacuum Switches
there are again
two categories:
Fixed Differential
Pressure Switches
and Adjustable
Differential Pressure
Switches.
In any application
when the potential
free contact is
required as soon
as the pressure
in process exceeds
desired pressure
limit (either
on rising side
or on falling
side). Fixed Differential
Pressure switches
are used. Such
switches are available
in Vacuum ranges
also.
In some applications
the pressure in
the vessel has
to be controlled
between two limits
higher and lower.
The switch which
has a facility
to set the gap
between higher
set value and
lower set value,
Such type of pressure
switches are known
as Adjustable
differential type
pressure switches.
We have both the
type of switches
available in pressure
range 15 mmwc
to 600 bar) and
vacuum range (50
mmWc upto 760
mmHg vacuum).
All these switches
are available
in IP 40, IP 54,
IP 65 or flameproof
enclosure. These
pressure switches
and vacuum switches
we can provide
in Aluminium,
Brass and SS pressure
housing and Teflon/Neoprene
diaphragm. Pressure
Switches can be
provided with
contact parts
as per process
requirements.
Pressure Switches
and Vacuum Switches
can be provided
with Diaphragm
Seals and Remote
Diaphragm seals
also. Repeat Accuracy
of our pressure
switches and vacuum
switches is better
than 1% FSR.
Vacuum Switches
are mainly used
for interlocks
inVacuum based
machines like
wrapping, packing
etc.
When output in
terms of mA or
mV if required
in proportion
to the pressure
available in process
vessel, Pressure
Transmitters or
Pressure Transducers
are used. Pressure
Transmitter and
Pressure Transducers
are normally available
with SS 316 wetted
parts for range
from few mmWc
up to 1000 bar
in IP 65 or flameproof
enclosure. These
can be provided

of filtration
systems, HVAC
and for flow measurement
through Orifice
plate.
Normally used
in the applications
where potential
free contact is
required when
DP crosses the
desired DP either
on rising or on
falling side.
We provide this
contact through
Micro Switches
or Reed Switches.
DP Switches are
available in wetted

It is considered
to be one of the
important parameter
in process industry.
Most of the process
in the industry
like Food, Chemical,
Pharmaceutical,
Petrochemical,
Textile, Tile
manufacturing,
Automobile, Automation
etc. depend upon
the variation
of the flow and
are necessary
to be indicated
or controlled.
Varieties of Instruments
for fluid flow
measurements are
available. For
different type
of liquids and
slurries. For
conductive fluid
(Electromagnetic
Flow Meter), for
clear water (Turbine
Flow Meter, Rota
Meter), for Oil,
Diesel, Petrol
applications (Positive
Displacement Flow
Meter i.e. PD
Meter), Non-contact
type flow measurement,
essential in few
Pharmaceutical
industries (Ultrasonic
Flow Meters).
NK Instruments
has also revolutionized
in the field of
electro-mechanical
flow meters by
introducing Floredo
which is battery
operated, digital
indication of
instantaneous
flow rate as well
as totalized flow
(Rate of Flow
with Totalizer)
without any mounting
restrictions with
better accuracy
compared to Rota
meters or any
of the water meters
used in industries.
For positive detection
of fluid flow,
Flow Switches
are used. Flow
Switches are available
for liquids &
Gases like, water,
kerosene, lubricating
oils, air etc.
Flow Switches
are used to ensure
availability of
desired flow or
no flow in your
system in order
to prevent or
to control any
disaster in the
industry. Magnetically
or Micro Switch
operated flow
switches are available
from 6 mm line
size. Magnetically
operated Flow
Switches (Blind
Flow Switches,
Flow Indicating
Switches) are
normally used
for low flow capacities
max. up to 150
LPM. Micro Switch
operated Paddle
Type Flow Switches
are an ideal solution
for higher flow
rates and bigger
line sizes.
According
to the type of
applications,
varieties of level
switches can be
provided.
For different
types of clear
liquids Float
type Level Switches
or Capacitance
type Level Switches,
for conductive
liquids Conductivity
type Level Switches
are used. For
dry powders and
pallets Rotating
Paddle type Level
Switch or, Vibrating
Fork type Level
Switches are recommended.
RF Admittance
Level Switches
can be used for
dry powders, pallets
as well as slurries
& pastes.
In pharmaceutical
Industries and
Effluent Treatment
plants only Non
Contact type Level
Switches are allowed.
In such applications
Ultrasonic Level
Switches can be
used. Level switches
can be provided
either side mounted
or top mounted.
Wetted parts in
Level Switches
are in Industrial
Plastic, PVDF,
Teflon, SS 316
or any special
as per the customer’s
requirement.
For
different types
of applications,
specific type
of Level Measuring
Instruments is
used. For liquid
Level Indication
by Mechanical
device, Tubular
Glass, Follower
type Level Indicator,
Bi-color Level
Indicators or,
float & board
type level indicators
are used. These
Level Instruments
can also be provided
with preset or,
factory settable
Level Switches.
Float type Level
Transmitter (Float
type Level Indicators)
are used where
4 to 20 mA out
put is essential
or, level indication
is required in
Digital display.
For non contact
type Level measurement
Ultrasonic or,
Radar type Level
Transmitters (Level
Indicators) are
used.
For online detection
and control of
conductivity of
fluid in any process
industry Conductivity
Meters or TDS
meters are used.
Normally the range
required is from
2 to 2000 micro
siemens.
On-line conductivity
indicators with
IP-65 plastic
enclosure for
corrosive or dusty
atmosphere as
well as Panel
mounted controllers

Density is a very critical
parameter in many industrial processes. It can be
measured either manual or, online methods. In manual
measurement systems, each sample has to be put in
the measuring bowl to take the reading of Density.
But in case of On line Density Measurement we can
pass the fluid through the density meter and the density
would be indicated instantaneously. Non contact type
on line Density meters working on gama rays are also
available, which are normally used for slurries, sewage
and liquids with highly sensitive, accurate real time
o-line measurement of Density. The density meters
are mainly used when variations in density of the
products affects the product quality or, its commercial
value. The industries like petrochemicals, Pharmaceutical
and food industries mainly requires the online density
measuring instruments. These instruments are designed
to withstand industrial environments while continuously
monitoring liquid composition in flowing streams,
ranging up to 2.5 kg/m3. Transmitters with accurately
dependable and highly repetitive can also be given
for control purposes.
Temperature is probably the most fundamental parameter
and is widely used to measure the industrial variable.
There are various types of temperature gauges &
Indicators such as Bi-metal temperature gauge, Mercury
filled temperature gauge (Rigid stem type), Mercury
filled temperature gauge (capillary type), Digital
temperature Indicators (using the Pt-100 or, RTD sensor).
The temperature ranges covered here is from -38 degree
C. to 600 degree C. with different mounting styles,
and process connections 3/8”, ½” BSP and NPT threads.
To control the temperature in the process, Temperature
Switches are used. Types of Temperature Switches are
either Mercury Filled blind Temperature Switches or,
Electrical contact type temperature gauges. In Electrical
Contact Temperature Gauges indication of Temperature
as well as switching contacts are provided. Electrical
Contact Gauges are available with capillary (up to
8 meters in copper, PVS and SS 316) also.
In
order to sense the presence of material moving through
a conveyer Proximity switches with electrical signal
through change over contact are used. There are two
types of Proximity Switches, one which works on Light
rays and the another which works on back pressure.
In Pneumatic Proximity Switches the switch actuates
on the back pressure developed by the air jet impact
on the object such as dimensioning, positioning,
and working surfaces. The distance sensed by this
switch is generally dependent on the profile of the
surface. This typically being 0.01 to 0.15mm.
