Model 1535 2-inch Stainless Steel
Pressure Gauges for Semiconductor
DESCRIPTION
SPECIFICATIONS
U.S. Gauge Model 1535 pressure gauges are designed
and manufactured for ultrahigh-purity gas distribution equipment used in semiconductor manufacturing.
These 2 inch, all stainless steel gauges are clean room
produced, nitrogen purged, and double bagged in 3 mil
nylon bag and 6 mil poly bag.
Size: 2 inch diameter
t These instruments are compatible with many toxic
and corrosive gases. Welded face seal connections provide a threadless pressure seal and virtually eliminate
a major source of contamination. Also available in NPT
connections.
t The Model 1535 is available in pressure ranges from
0 to 30 inches Hg VAC, to 0 to 4000 psi. This precision
gauge incorporates rugged case construction with rear
pressure relief, and a seamless Bourdon tube with welded joints for heavy-duty service.
Case: Drawn stainless steel polished with pressure relief in
back of case
Ring and Window: One piece, threaded polycarbonate, or
optional friction ring with polycarbonate or glass lens
Pointer: Aluminum, adjustable zero, black finish
Dial: Aluminum, white background with black markings
Bourdon Tube: Type 316L seamless stainless steel
Connection: Type 316L stainless steel, low mount or center
back mount, male or female face seal fitting, or 1/4 inch male
NPT – connectors are shipped with protective plastic caps
Surface Finish:
Face seal connections: 10 Ra
1/4 inch NPT connections: 32 Ra
Ranges: 30 inches Hg vacuum to 4000 psi, single or dual scale,
see ordering information
Overpressure: 110% of span maximum
FEATURES
●● Cleaning for UHP gas applications exceeding ANSI
B40.1 specifications
