Relative and differential pressure module type 698 Pressure range -5 ... 5 mbar / 0 ... 1 10000 mbar The pressure modules type 698 are suitable for monitoring pressure and flow in air conditioning systems and in the laboratory sector. The module is optionally available with a 3 digit LED display, two limit value switches (potential free) as well as a square root extraction. Rugged measured value detector, owing to outstanding synergy obtained by combining diaphragm technology with a cermaic element High overpressure safety margin, even in the lowest pressure range Easy to install and commission No maintenance required High Protection standard Huba Control type 698 - Technical data subject to change - Edition 10/2010 1/5 Technical overview Pressure range -1 ... 0 bar 0 ... 10 bar -5 ... 5 mbar 0 ... 500 mbar Relative Differential Operating conditions Medium Temperature Differential pressure Relative pressure Tolerable overload on one side Differential pressure Rupture pressure Relative pressure Medium Ambient Storage 0 ... 50 mbar 0.1 ... 10 bar 0 ... 50 mbar 100 ... 500 mbar 0.1 ... 10 bar Materials in contact with the medium Pressure connections Hose connection Diaphragm Sensor housing Sealing material Sensor Air and neutral gases 0 ... +70 ÀC -10 ... +70 ÀC -40 ... +70 ÀC 100 mbar 3x fs 1) 200 mbar 5x fs 3x fs 1) PVC Silicone / PA Silicone / Al2O3 (96%) / Silicium PA, PC, Ultem NBR Al2O3 (96%) / Silicium Electrical overview Output (Selectable by customer) Power supply Tolerable load Current consumption Extra-low voltage Low voltage Polarity reversal protection 0 ... 10 V 0 ... 20 mA 4 ... 20 mA 17 ... 33 VDC 24 VAC 115 VAC 230 VAC 0 ... 10 V > 2 kOhm 0 ... 20 mA / 4 ... 20 mA < 500 Ohm < 4 VA Each connection is protected against crossover up to max. power supply 230 VAC / 115 VAC only on supply terminals, transformer short-circuit Dynamic response Response time Load cycle < 20 ms < 10 Hz Protection standard IP 65 Limit switches Two potential free change over contacts adjustable over the full range (Adjustment with potentionmeter).
