Aplisens Smart differential pressure transmitter

 Smart differential pressure transmitter with APRE-2200ALW or APRE-2200

The differential pressure transmitter is applicable to the measurement of pressure differences of: gases, vapours and liquids in cases where it is necessary to use seals and the pressure pulse source points may be several metres apart. Typical applications include the hydrostatic measurement of: levels in closed tanks, densities and phase boundaries, and the measurement of a filter loss, pressure differences between media in pasteurisers etc. The available range of the diaphragm seals allows measurement at great majority of media. The active element is a piezoresistant silicon sensor separated from the medium by a distance sealing system. The special design of the measuring unit means that it can withstand pressure surges and overloads of up to 40 bar. The electronic circuits are enclosed in a casing with a degree of protection IP 65 or IP66.

Technical Data

Nominal measuring range (FSO)	Minimum set range		Vertical spacing of diaphragm seals		Maximum set range width, considering the actual vertical spacing of the diaphragm seals (m)	Static pressure limit
-160…160 mbar	0,1 m H2O		≤ 1,7 m		[1,6 + (vertical spacing of seals × 0,94)] m H2O	40 bar
-0,5…0.5 bar	0,5 m H2O		≤ 6 m		[5 + (vertical spacing of seals × 1,04)] m H2O	40 bar
-1,6…2 bar	1,5 m H2O		≤ 15 m		[20 + (vertical spacing of seals × 1,04)] m H2O	40 bar
-1,6…16 bar	1 bar		≤ 15 m		16 bar	40 bar

CAUTION: The maximum vertical diaphragm seal spacing shown in the table applies to level measurement, ensuring that it is possible to set the zero point of the transmitter when the tank is empty. For measurements of density or phase boundaries (in the sugar, chemical or refinery industries) the vertical spacing of the diaphragm seals can be larger.
