The Price RPN provides a means for
measuring the relative pressure between
the pressurized underfloor plenum and
the room. The RPN is designed to fit inside
any style of mounting ring underneath any
Price round floor diffuser. The advantage
to the RPN is that it maintains a uniform
look with other Price underfloor diffusers.
Its ability to be hidden and yet maintain less
than 1% error in its pressure measurements
makes the RPN a very useful product for
UFAD applications with plenum pressure
control. The RPN comes with an integral
pressure transducer that is highly accurate
at the very low static pressures normally
present in pressurized underfloor plenums.
Features
- 1/4" integrated pressure tap.
- Keyed edge to prevent spinning of
diffuser under load.
- Shallow profile allows for use in
underfloor plenums as shallow as 2".
- Black finish allows the RPN to be visually
hidden from the room side.
- Integral 24 VAC pressure transducer with
0-10 VDC output.
- Monitor relative plenum pressure
through a floor diffuser for consistant
look.
Construction
Available Sizes
Installation
The relative pressure node (RPN) uses its
integral pressure transducer to sense the
pressure differential between the plenum
and the room air. The signal is sent to the
underfloor pressure controller (PCU). The
PCU regulates one or more supply air
damper to maintain the pressure set-point,
which may be adjusted via a thermostat
located in the room.
