Specification sheet Deltapi N Series
Pneumatic Transmitters
Model NAE
Differential pressure transmitter
with remote diaphragm seals
The blind type differential pressure transmitter, mod. NAE, is
used to measure a differential pressure and convert it into a
proportional pneumatic signal.
The instrument works on the force-balance principle and
consists of two main units:
the measuring unit is formed by two AISI 316 forged
halfbodies, measuring capsule and two diaphragm separators
completed with capillaries.
A double diaphragm capsule is placed within two halfbodies to
releve the differential pressure transmitted by the two liquid
filled separators and capillaries.
The capsule is available in two versions: 2in or 3in diameter
diaphragms, filled with a special liquid which can withstand the
maximum rated static pressure on either side without damage.
the transmission unit converts the differential force applied to
the measuring element into a proportional output pneumatic
signal.
The output pressure, generated by a flapper nozzle relay, is fed
to a feedback bellows with a rising pressure until the bellows
force balances that of the measuring element.
Span value continuously adjustable by an internal micrometric
screw.
Zero value adjustable by an external screw.
Mounting in a vertical position on 2in diameter pipe by a
special bracket.
OPTIONAL EXTRA FEATURES
A zero elevation or suppression device allows to set as a
zero of the transmitter a measured variable value different from
zero.
Zero suppression value (S) added to the calibrated span must
never exceed the upper range limit (M) of measuring capsule:
S + span M (see table).
GENERAL CHARACTERISTICS
Air filter regulator can be directly mounted on the transmitter,
with or without pressure gauge, and connected with piping and
fittings either in stainless steel or copper.
Special versions of air filter regulator and gauges, in stainless
steel, are available on request.
