| RT
Series of Pressure Switches utilize
seamless bellows as the sensing element.
Simplicity of design and ease of installation
has been stressed for reliable use,
even in applications where shock and
vibrations are present. The sensing
element can be used for a variety
of process fluids. |
| For
corrosive media, viscous fluids and
slurries, RT pressure switches perform
well in conjunction with diaphragm
type chemical seals. |
|
|
|
|
| RT Series
of Temperature Switches have a vapour
filled thermostatic element, which
consists of a sensing bulb, capillary
tube and a bellows element. The entire
element contains a charge which reacts
to temperature variations at the sensing
bulb, so that pressure on the bellows
increases on rising temperature. The
bellows movement due to this increase
in pressure is utilised to operate
the switch. |
| |
| Available
in various ranges to control temperature
upto 300°C, with high over temperature
limits. RT temperature switches are
available with a selection of capillary
lengths. The vapour filled system
features small bulb sizes making installation
easy. |
| |
| Wherever,
bulb of temperature switch is exposed
to pressure, corrosive fluid or high
velocity, a thermowell must be used.
Threaded or flanged thermowells, with
length and materials as per application
requirement are available. |
| |
| RT series
switches have an excellent record
backed by our responsive manufacturing
facility. Special application assistance
is always available. |
| |
| Applications
include pumps, compressors, filters,
evaporators, heat exchangers, lubrication
systems, hydraulic systems, marine
equipment, heating and air conditioning
equipment, turbines, generators, circuitbreakers
etc. |

SWITCH - AST SERIES |
| |
 |
Type
AST Temperature switch has been specifically
designed for use on Diesel Locomotives
to safeguard the engine from damage
that could be caused by excessive
heat. However these switches can be
used for other applications also.
These switches are of direct mounting
design. |
| |
| The
thermal sensing element of AST temperature
switch consists of a metallic bellows
and sensing bulb. This thermal element
is filled with a partial vapour charge
, the pressure of which rises with
the increase in temperature at the
bulb. When the temperature exceeds
the preset value , the pressure in
the thermal system increases and overcomes
an opposing spring force to actuate
an electrical microswitch. The entire
assembly is housed in a uniquely designed
die cast aluminium enclosure which
allows ease of installation and wiring
. |
