Your
pressure switch comes with the 0.7mm section stainless steel spring already
fitted. This is the mid-range option.
The red
spring is strong and rated from 14psi onwards. You will also have a 0.6 and a
0.5mm section spring for fine tuning adjustments.
You will be
able to read the strongest spring rating laser etched into the body of the
switch. (in MPa)
Some users
like to run dual stage water injection for example, the lighter springs
accommodate for this, and can be tuned to be activated from around 3 psi
(+-1psi)
Unit thread
size is 1/8 npt.
If exposed
to high temperatures this switch needs to be protected with suitable
insulation.
It can be
mounted anywhere in the line after your compressor outlet (engine inlet), or “divorced”
remotely fed with a tube, again of suitable material, if high temps are going
to be an issue, best mounted to the bulkhead for example.
Switch
adjustment. You will need to either set
up a pre-set rig, with a bike pump, compressed air, etc (use your imagination)
and a basic light bulb circuit, using a pressure gauge and a 12v bulb. Alternatively,
using a boost gauge, set with the light bulb circuit in car using small trial
and error adjustments until your desired switch operating pressure.
When setting the
final adjustment, secure thread using semi-permanent/permanent, anti-vibration
media like Loctite, silicone sealer, mastic, butyl, blue tac, paint, epoxy
resin, chemical metal etc.
