Accuracy (acc. to ASME B.40.100)

• ±1.6% of Span

• ±2.5% of Span for pressure ranges 0-600 and 0-1,000 bar (0-10,000 and 0-15,000 psi)

Case Wide bayonet ring, polished (American case type), 1.4301 (304 stainless steel)

Case Protection Type (EN 60 529 / IEC 529)

• IP54

• IP65 for model RChaG (pressure ranges ≥ 2.5 bar and above), for case configuration Fr and closed blow-out plug

Blow-out Device
