Description
Accuracy
0.066% of full scale
Repeatability
0.03% of full scale
Sensitivity
0.01% of full scale
Hysteresis
0.1% of full scale
Readability
0.02% of full scale
Temperature effect
Maximum is 0.1% of full scale per 10°C/18°F change from reference temperature 23°C/73.4°F
Scale length
45 in. (1140 mm) through 2 pointer revolutions
Dial diameter
8 ½ in. (215 mm)
Capsule system volume
6.9 cc with pointer at zero; 8.6 cc, at full scale
Case volume
3070 cc
Case pressure
35 psi (2.5 bar) maximum
Overpressure protection
A pressure relief valve protects the mechanism (capsule); pressure up to 90 psi will not damage the mechanism nor affect accuracy. A built-in relief valve and a flow restrictor rotect the case from pressures up to 10 times the case rating of 35 psi. This valve is an emergency-protective device only.
Maximum case leak rate
Will not exceed 1.03 x 10-7 std cc / sec or 0.018 psi / hr
