Sereis 1500 Absolute Pressure Gauge Series 1500 Gauges pressure elements are capsules up to and including the 50 psia range: 100 psia and above use Bourdon tubes. In the former, pressure is applied to the case and is referenced against the evacuated capsule. In the latter, pressure is applied to a Bourdon tube, which is referenced against an evacuated Bourdon. Available in 14 standard ranges, Series 1500 Gauges combine aneroid convenience with liquid-column accuracy. And they are rugged enough to maintain their high accuracy in all kinds of test and process applications.
