Nex Flow user-friendly PLC flow control
system (PLCFC) for
compressed air is truly advanced and uses the
most modern technology
available today and can be
used as a standalone unit or interfaced with
other automated systems. The PLCFC is a PLC
based system - not just a simple timer. It is
not just a simple, often overpriced sensor and
The PLCFC combines a photo
electric sensor to turn on the air when the
target passes the sensor and to turn off the
air when it leaves the sensor. (The unit is
set to have a 2 second delay after it leaves
the sensor but turns on instantaneously when
it sees the target). We can supply an optional
timer if the customer wants to set the unit
to turn off based on time rather than using
the sensor to turn it off.
Unlike many competitive units, which only offer a simple on-off with timer,
it does not really optimize the air use if the
timer is set wrong and leaves the system running
far longer than necessary.
We can control not only solenoid valves for on-off but can control any electrical
devices such as motors, fans, conveyor motors
that carry the parts, etc.
Also, our systems which come complete with one sensor, can operate with
up to eight sensors (not just optical, but proximity
switches and other kinds of sensing devices)
for a multiple of independent tasks. Each task
can be programmed. Nex Flow can offer
the service of special programming according
to customer needs.
In addition, you have a choice of any one of two types of sensors - a 500
mm sensing range diffuse type (no reflector
needed) or a 3000 mm sensing range reflector
type - all depending on the need. Other special
sensors can be supplied on request such as laser
All this comes in a simple package at almost the same cost as the competition!
The system can be programmed to suit any special application the customer
may have for blow-off systems, other automation
applications or it can be tied into existing
It is easily connected for either 110V or 220V making it suitable for applications
around the world. Designed for use in the industrial
environments including wet ones, this rugged
unit is easy to install in tight places - flexible
and easy to use and adaptable.
Easy to install and hook up - 110V to 220V
Suitable for NEMA 4/IP56 environments
Compact sensor for mounting in tight spaces
Optional timer if desired - unit comes preset for tight on-off control for best results in saving air - a true optimizer
Box has four mounting lugs for easy mounting
Choice of sensors for use up to 3000 mm (10 feet)
Sensors withstand water dust, oil, and coolant.
Sensors have superior immunity to noise and inductive loads
PLC Flow Control System (PLCFC) - The PLCFC
combines a photo electric sensor to turn on
the air when the target passes the sensor and
to turn off the air when it leaves the sensor.
(The unit is set to have a 2 second delay after
it leaves the sensor but turns on instantaneously
when it sees the target). In one example using
an air knife, compressed air enters at point
(A) into the air knife (B) only when the sensor
(C) sees the target. The PLCFC is located at
point (D). The target part (E) passes the sensor
activating a solenoid to turn on the air flow
to the air knife. The target travels on the
conveyor (F). Two seconds after the target has
passed the sensor, the air supply is turned
off conserving energy. Different sensors are
available for different applications and the
units can be programmed for special applications.
