Series 1000 6" Dial High Precision Gauge Pressure Indicators

Series 1000 6" Dial High Precision Gauge Pressure Indicators Series 1000 gauges have capsules up to and including the 150 psig range and Bourdon tubes in the higher ranges. Pressure is applied to the capsule or Bourdon tube through a single case connection. Readings are referenced to atmospheric pressure in the case. Available in 26 standard ranges, (including vacuum and compound ranges) Series 1000 Gauges combine aneroid convenience with precision-liquid-column accuracy. They are compact, yet readability is excellent.

STANDARD FEATURES

Ranges:
to 1000 psig
Accuracy:
0.1% of full scale
Repeatability:
0.03% of full scale
Sensitivity:
0.01% of full scale
Hysteresis:
0.1% of full scale for ranges of 150 psi and below;
0.2% of full scale for 200 psi and above
Maximum temperature effect:
0.1% of full scale per 10°C/50°F change from 23°C/73.4°F
Scale length:
30" through two pointer revolutions
Dial diameter:
6"
Pressure element volume:
Ranges 150 psi and below: 6.9 cc with pointer at zero; 8.6 cc, at full scale.
Ranges 200 psi and above: 10 cc. For the range 1-125 inH2O only: 6.3 cc with pointer at zero; 8.0 cc, at full scale
Liquid service:
Gauges with ranges of 200, 300, and 500 psi (Bourdon tubes) can be calibrated for liquid service as an option. The 0-1000 psi range is calibrated for liquid service only.
Case pressure:
Cases are open to atmosphere.
Bleed tube:
Ranges of 200, 300, and 500 psi (Bourdon tubes), when calibrated for liquid service, have bleed tubes to facilitate filling and flushing. On the 1000 psi range, a bleed tube is standard.
Case connections:
150 psi and below, 1/8" female NPT; 200 psi and above, 1/4" female NPT. Both have a built-in stainless steel filter and are located in the bottom of the case.
Case construction:
Anodized aluminum with high-strength, scratch-resistant plastic dial cover. Bezel has no screw holes; the case has special clips, which make flush mounting easy.
Zero adjustment:
A zero adjustment is accessible through the front of the case.
