The manufacturing of these precision pressure gauges and calibrators has been relocated from Germany and are now being made 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 Differential Pressure Gauge

Series 1500 Differential Pressure Gauges have capsule-type pressure elements. High differential pressure is applied to the capsule; low pressure to the case. Available in 22 standard ranges, they combine aneroid convenience with liquid-column accuracy. And they are rugged enough to maintain their high accuracy in test and process applications.

STANDARD FEATURES

Size: 8½" dial

Scale length: Approx. 45" through 2 pointer revolutions

Range: To 150 psi

Accuracy: 0.066% of full scale

Sensitivity: 0.01% of full scale

Hysteresis: 0.1% of full scale for all ranges except 150 psi or equivalent, which is 0.2% of full scale

Maximum temperature effect: 0.1% of full scale per 10°C/50°F change from 23°C/ 73.4°F

Pressureelement volume: 6.9 cc with pointer at zero; 8.6 cc at full scale.

For the range 0-125” water only: 6.3 cc with pointer at zero; 8.0 cc at full scale

Case volume: 3070 cc

Maximum case pressure: 35 psig

Maximum case leak rate: Will not exceed 1.03 x 10-3 std cc/sec or 0.018

psi/hr

Case connections: 1/8" female NPT pressure and static connections. Stainless steel filters are mounted in the orifice of both units and are located in the bottom of the case.

Case construction: Cast aluminum with tempered-glass dial cover; flush mounted by three screws through the bezel.
