Ashcroft 251009SW02BXFFSGN1/1.5BR/#
2.5" SS Bourdon Tube Compound Gauge, -30 inHg/+15 psi (≈-1/+1.5 bar), 1/4" NPT Back, Panel Mount, Dry
Ashcroft Type 1009 Duralife, 2.5 in (63 mm) dial, all-stainless construction: 316 stainless steel Bourdon tube with a 316L stainless steel process connection, 304 stainless steel case and removable 304 stainless steel bayonet ring. The configuration 251009SW02BXFFSGN1/1.5BR/# is the dry gauge with a 1/4 in male NPT back connection on the case centreline, a front flange for flush panel mounting, a safety-glass window in place of the standard polycarbonate, and a dual-scale dial reading -1/0/1.5 bar on the inner scale with 30 inHg/0/20 psi on the outer scale. Three differences a buyer should weigh before substituting. Accuracy: the Ashcroft is built to ASME B40.100 Grade 1A at plus or minus 1.0% of span, while the General Instruments gauge listed here is built to EN 837-1 Class 1.6 at plus or minus 1.6% of span. Across this 2.5 bar span that is about plus or minus 0.040 bar against plus or minus 0.025 bar, so the substitute is the looser of the two. Ambient temperature: the Ashcroft dry gauge is rated -40 to +93 C ambient; this gauge is rated -20 to +60 C. Confirm the mounting location before substituting in unshaded outdoor service, in compressor or engine houses, or anywhere else the panel runs hot. Panel mounting: the Ashcroft 2.5 in front flange takes a 64 to 66 mm panel cut-out with three 4.1 mm holes equally spaced on a 79.5 mm bolt circle. This 63 mm gauge uses the metric 63 mm front-flange pattern, so confirm the panel drilling before reusing an existing cut-out. Measuring range, second scale, dial size, connection size and thread form, connection position, dry case prepared for filling, case and wetted materials, and the glass window all correspond.
