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.
