Specification sheet Deltapi N Series Pneumatic Transmitters Model NAE Differential pressure transmitter with remote diaphragm seals GENERAL CHARACTERISTICS 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). 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.
