burners. Ideal for compressors, turbines, filters, blowers, etc. |
 |
Single Setpoint Explosionproof Enclosures
Ashcroft 700 series
has been developed for most applications found in process plants U.L. or
CSA LISTED. All models have similar performance characteristics to the
popular Ashcroft B400 Series switch line, which has been used throughout
the world’s plants and mills for over 25 years. They feature rugged,
reliable diaphragm-sealed piston actuators, snap-acting contacts and
all-popular wetted materials and process connections. Dual Seal Rating
models available. Optional hermetically sealed contacts, Monel or
fire-safe actuators and scores of options allow you to choose a model
for any application. |
|
 |
Dual Setpoint Watertight Enclosures
Easy to use L-Series
switches are specifically suited for the OEM seeking more features in a
snap-acting switch. Single or dual setpoints and fixed or adjustable
dead-band models with many wetted materials and electrical ratings are
offered. This snap-acting switch also replaces older mercury models and
is cost effective. L-Series switches are ideal for blowers, generators,
scrubbers, precipitators, compressors and turbines. |

suitable for OEM configuration. |
 |
Electronic Pressure Switches
The Ashcroft
N-Series electronic pressure switch combines the popular K-Series
poly-silicon thin film pressure transducer sensor and rugged,
epoxy-coated enclosures. The result is a highly reliable pressure switch
that is ideal for high cycle, high pressure, or difficult deadband
applications. Typical applications include: machine tools, injection
molding machines, presses, pumps, hydraulic systems, turbines, and
compressors. |
|
|
Standard Differential Pressure Switch
Small size and high
overpressure capability make our differential pressure switch ideal for
most process and industrial applications. Minimum static working
pressures of 500 psi allow use on the most difficult filter
applications. We use a unique combination of diaphragm-sealed piston
actuators to get our high static pressure performance in 12 ranges. For
inches of water ranges, we use a large diaphragm for sensitivity which
results in lower, more conventional working pressure. Consult the
factory for application assistance on differential pressure switch
selection. |
|
ATEX Approval for Hazardous Locations
ATEX is a European
designation that deals with standards for equipment and protective
systems intended for use in potentially explosive atmospheres. This
approval is required for switches intended for use in hazardous
locations, especially important to OEMs who export to Europe and
contractors specifying or purchasing products for European applications.
XCN option adds special features to Ashcroft 700-Series switch
enclosures that meet the requirements for the highest levels of security
and danger. |
|
|
U.L. Listed Steam Limit Control
The Ashcroft
steam-limit control switch is designed for use on boilers equipped with
electrically operated burners. The limit control is an adjustable
pressure-operated switch set to stop burner operation when the
recommended safe boiler working pressure is exceeded. We recommend a
stainless steel diaphragm for steam service. A pigtail siphon should
also be used to reduce the possibility of high temperature affecting
switch performance. This listing is available for setpoints up to 300
psi. |
|
U.L. Listed Pressure Limit Control
The Ashcroft
medium-pressure gas and oil limit control switch is designed for use
with air, LP gas, natural gas, #1 and #2 fuel oil and #6 oil preheated
to 240°F. This limit control is an adjustable pressure-operated switch
with a secondary chamber to prevent fuel from entering the switch
enclosure in the unlikely event that the diaphragm develops a leak. The
control shuts down a fuel pump in high or low pressure conditions. |
