The manufacturing of these precision pressure gauges and calibrators has been relocated from Germany and are now being done in the U.S. by WIKA Instrument Corporation. They are certified to NIST Standards before shipment. The Certificate of Calibration is included at no additional cost

Series 1500 8½;" Dial High Precision Absolute Pressure Gauges

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.

STANDARD FEATURES

Sizes: 8½" dial

Scale length: To 500 psia

Accuracy: 0.066% of full scale

Repeatability: 0.03% of full scale

Sensitivity: 0.01% of full scale

Hysteresis: Below 100 psia, 0.15% of full scale; 100 psia and above, 0.1% of full scale

Maximum temperature effect: Below 100 psia, 0.019% of full scale per 10°C/ 50°F change from 23°C/73.4°F; 100 psia and above, 0.1% of full scale per 10°C/50°F from 23°C/73.4°F.

Case pressure and volume: For gauges with ranges below 100 psia, maximum case pressure is 35 psig, case volume is 3070 cc. For gauges with ranges of 100 psia and above, volume of the pressure Bourdon system is 10 cc and the case is vented to atmosphere.

Maximum case leak rate: Will not exceed 1.03 x 10-3 std cc/sec or 0.018 psi/hr in ranges below 100 psia; 100 psia and above, case is vented to atmosphere.
