The direct drive of lightweight, precision balanced pointer reduces friction and mass, improving responsiveness and accuracy. So well, in fact, that on ASME Grade 2A or 3A models the accuracy is built in for life! Center post bearing carrier ensures precise bearing alignment for nearly friction free operation. Low volume Bourdon tube reduces fluid volume and stored energy, reducing potential for damage if tube ruptures from overpressure or other causes. A large area filter keeps dirt out and restricts flow from damaging the Bourdon tube. The smaller diameter tubing combined with a solid front case and rear blowout plug provides added safety.
Convenience is enhanced by dual bottom and back process connections on panel mount models while Turret housing gages possess a dual 1/4" female NPT and 1/2" male NPT bottom connection. Impact resistant plastic case is sized to conform to ASME B40.1, replacing existing gages without changes in panel cutout or mounting holes. Compound ranges are available in either panel or turret style housings for applications where vacuum is present in the process.
