Dwyer Instruments 7112-G030-NIST
Direct Drive Pressure Gage Range 0-30 psig
The Series 7000 Spirahelic® Pressure Gages employ a unique triple helix Bourdon tube for
precision measurement of compatible gases and liquids. The direct drive design reduces
friction and mass, resulting in exceptionally good responsiveness, repeatability and accuracy.
Because there are no gears, springs, linkages or other complicated mechanisms, wear is
practically eliminated. Solid brass or 316 stainless steel connection block features convenient
dual 1/4" female NPT ports-one each on back and bottom. Block also includes integral filter
plug to keep dirt out. Safety is assured with solid front case design and rear blowout hole.
Gages fit ASME standard panel cutouts, 4.94" (125 mm) -7100; 6.5" (165.1 mm) -7200; 9.0"
(229 mm) -7300.
