Dynamic pressure monitoring on the clamping slides
The quick-change pallet module NSP 140 features dynamic
pressure monitoring on the clamping slides.
It is therefore possible, for example, to monitor the dynamic
pressure on the clamping slides of the quick-change pallet module
using an electronic pressure switch. This means the slide position
can be monitored electronically in order to ensure that the
clamping slides are in an unlocked position. This way, the clamping
system can be protected from any possible damage.
The measurable differential pressure must reach a minimum of
1 bar for assessment via the air gap sensor to be reliable. The
maximum pressure is 2 bar and 15 l/min volumetric flow.
Monitoring requires a pressure gauge, an adjustable throttle and
an air gap sensor.
The air connection is made the standard way via the coupling bore
on the lower face side of the quick-change pallet module. Sealing
the air connection (please refer to chapter "Fastening and
connection"
(

6.2, Page 19) ). Use of the dynamic pressure
monitoring function is not mandatory for the basic operation of
the clamping module.
For slide monitoring for "Module opened", the clamping modules
of a clamping station (connected in parallel) can be monitored via
a pressure switch. For slide monitoring for "Module clamped", the
clamping slides must be monitored individually via their own
pressure switch.
Electrical cylinder piston stroke monitoring
The quick-change pallet system NSP-S 140 features electrical
cylinder piston stroke monitoring.
Here, the cylinder piston stroke is monitored via a magneto-
inductive sensor.
A magnet is fixed in the cylinder piston. The movement of the
magnet causes a change of the magnetic flux in the sensor
element, which is detected by the sensor coil.
The sensor provides a physical output voltage of 2 – 10 V. The
supply voltage is 11.5 – 30 VDC.
The signals are transmitted via spring contact pins in the module
and via rigid contacts in the counterpart (machine table).
