Adjustable Pressure Switch simplifies setting
of system pressures in the field.
New from PVL is an adjustable pressure switch that will
simplify the lives of engineers who need to tweak hydraulic,
pneumatic or lubrication systems during set up, or who
need to monitor system pressures on the fly.
The innovative PSK pressure switch provides simple adjustment
of system pressures, with two models covering the key ranges
of 10-1 O0bar and I 00-36Obar.
With its large adjusting knob, easy-to-read graduated pressure
scale and fixed hysteresis, the PSK provides simple yet reliable
adjustment of system pressure, and has been particularly
designed to help engineers monitor and set minimum or
maximum pressure in fluid circuits. Once the correct pressure
has been established, the device can be locked off via a set-point
fastening screw.
Whilst the PSK is not intended to provide absolute accuracy, it
will prove an immensely useful tool for adjustment in the field,
and the accuracy available belies the simplicity of the adjustment
mechanism, comments PVL's Steve Moorey. It would be invaluable
for hydraulics engineers who need to set pressure relief valve
switches, but who don't actually know the required pressures
until they get out in the field.
The PSK features an SPDT contact rated at 3A, 220V AC or 5A,
125V AC. For operation from 10-1 O0bar, the PSKI 00 features
diaphragm execution, with a robust design that will survive
over-pressure to 300bar. For operation from 100-36Obar, the
PSK360 features piston execution, and will survive over-pressure
to 600bar.
Rugged and robust, the PSK adjustable pressure switch is
constructed from anodised aluminium, and features an aluminium
adjusting knob, with the whole construction sealed to 1P65.
Mounting options include CETOP manifold or 1/4in BSP pipe
fitting, affording high levels of mounting flexibility.
Based on proven pressure switch technology, the highly reliable
device offers a mechanical life in excess of one million operations.
