1 Specification sheet eltapi N Series Pneumatic Transmitters Model N auge pressure transmitter with remote diaphragm seal ENER HRTERISTIS The blind type pressure transmitter, mod. N, is used to measure a 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 comprises a main body which houses a bellows unit, connected via a capillary pipe through the positive connection port to a separator forming one all-welded system filled with a separating liquid. The negative connection port is open to atmosphere. The bellows unit is clamped in the main body forging by means of a flange and it can withstand the maximum overrange on positive 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 in diameter pipe by a special bracket. OPTION EXTR FETURES 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 of measuring element : S + span M (see table). ir 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.
