| DIFFERENTIAL
PRESSURE SWITCHES TYPE D |
| |
 |
Indfos
D Series Differential Pressure Switches
are produced using technology provided
by Dresser Industries USA (ASHCROFT
Division). These are sturdy, robust
and precise devices for use in process
industries. |
| Available
in various ranges covering differential
pressures from 25 mm to 42 kg/cm2
ranges, these switches utilize a dual
diaphragm sealed piston sensor which
is capable of withstanding extremely
high static pressures and at the same
time provides set point repeatability
of ±1%. Diaphragms are available
in Buna-N, Viton, Teflon, Kapton,
Stainless steel & Monel construction
making the switch suitable for virtually
any process fluid. |
| |
| Enclosures
are available in weather proof (IP
66) and explosion proof (II A, B &
C) versions and are die cast aluminium
as a standard. A wide variety of 1
SPDT or 2 SPDT microswitches including
hermetically sealed microswitches
are available to meet different requirements
of electrical ratings and environmental
conditions. |

| DIFFERENTIAL
PRESSURE SWITCH - TYPE IPSD |
| |
 |
IPSD
50 Differential Pressure Switch is
an electromehanical device that senses
changes in pressure difference between
two pressures lines and provides electrical
contact closure at predetermined values.
|
|
The mechanism is enclosed in a
dust proof mild steel casing and
all parts are rust proofed for long
life. It is designed for use with
oil, air, water and steam.
