Diaphragm Pressure Gauges

Diaphragm Pressure Gauges Applications: For measuring points with increased overpressure For gaseous, liquid and aggressive media, also in aggressive ambience With the open connecting flange option also for particulates-containing and viscous media Process industries: chemical/petrochemical, power stations, mining, on- and offshore, environmental technology,machine building and plant construction Nominal size in mm: 100, 160 Scale ranges: 0 ... 16 mbar to 0 ... 250 mbar (flansch-Ø 160 mm) 0 ... 400 mbar to 0 ... 40 bar (flansch-Ø 100 mm) or all other equivalent vacuum or combined pressure and vacuum ranges. Movement: Stainless steel(SS304) Dial: Aluminium, white, black lettering. Pointer. Aluminium, black,Adjustable pointer. window: Generally tempered glass ,Laminated safety glassbe requested Bezel ring: Cam ring (bayonet type), stainless steel(SS304) Diaphragm sealing ring: FPM/FKM Upper diaphragm housing: Chrome steel Case: Stainless steel(SS304), with pressure vent Liquid filling (for Model ASN150): Glycerine accuracy class: 1.6 Ingress protection: IP 54 Pressure element: ≤ 0.25 bar: stainless steels(SS304 OR 316L) > 0.25 bar: NiCrCo-alloy (Duratherm) Overpressure safety; 40, 100 or 400 bar operating temperature: Ambient: -20 ... +60 °C Medium: +100 °C maximum working pressure: steady: 3/4 of full scale rang fluctuating: 2/3 of full scale range short time: full scale range temperature effect: When the temperature of the measuring system deviates from the reference temperature (+20 °C):max. ±0.4 %/10 K of full scale value Pressure limitation: Steady: full scale value Fluctuating: 0.9 x full scale value Process connection with lower diaphragm housing: Stainless steel, G ½ B (male), 27 mm flats Special versions: Gauges for ammonia plants (ASH 100 and 160) With temperature scale for refrigerant R 717 (NH3) in °C, scale ranges: -1 ... 0 ... 15 bar or -1 ... 0 ... 26 bar options: Other process connection Liquid filling (model DA100) Safety pattern version Vacuum safe to -1 bar Medium temperature >100 °C Open connecting flanges per DIN/ASME Wetted parts made of special materials, high overpressure safety up to 10 bar (flange Ø 160 mm) or 40 bar (flange Ø 100 mm): PTFE (Hastelloy B2, Hastelloy C4, Monel, Nickel, Tantalum,Titanium) Alarm contacts Gauge with integrated transmitter Version per ATEX Ex II 2 GD c Special version: Modelhg150 high overpressure safety up to 400 bar Case with blow-out back Scale ranges: 0 ... 25 mbar to 0 ... 250 mbar (flange Ø 190 mm) 0 ... 400 mbar to 0 ... 40 bar (flange Ø 120 mm) Flange connecting screws: steel, corrosion-protected Ordering information: Model / Nominal size / Scale range / Connection size / Connection location / Options Modifications may take place and materials specified may be replaced by others without prior notice.Specifications and dimensions given in this leaflet represent the state of engineering at the time of printing.
