NOTE: Product codes are specified in psi based on maximum

capability of the bourdon tube assembly. Full scale pressure

range and units of measure must be specified by special

instructions in addition to the product code. For example 10,000

psi range would be specified and special instructions “Calibrate

0-600 Bar”

NOTE:

1.) Hysteresis may exceed 0.1% of span for ranges of 75,000 psi or

greater. 0.3% is typical, not to exceed 0.4%.
